All prices are estimates based on current listings from Nairobi retailers, repair shops, and electronics suppliers as of mid-2026, including platforms such as Jiji, Jumia, Universal Tech Electronics, Nerokas, Prologic Technologies, Refitec Kenya, and GossTech. Prices are subject to change. Always confirm with your supplier before purchasing. Labour/installation costs are listed separately where relevant.
1. LED Backlight Strip
Television LED Backlight Strip: Estimated Prices in Nairobi for Different Sizes and Brands
The LED backlight strip is one of the most frequently replaced components in modern flat-screen televisions. It sits behind the LCD panel and provides the light that makes the image visible. When a strip fails, the screen goes dark or develops dim patches — often while sound continues normally. In Nairobi, backlight strips are widely available through TV repair shops and electronics suppliers, making this one of the more accessible repairs.
What affects the price? Strip prices depend primarily on screen size — a 32-inch strip costs far less than one designed for a 65-inch set. The brand and model of the TV also matter, since strips are not universal; a Samsung-specific strip differs from an LG or Hisense equivalent. Generic compatible strips are cheaper than OEM-branded versions.
| Screen Size | Generic Compatible Strip | OEM / Brand-Specific Strip | Estimated Labour |
|---|---|---|---|
| 32 inch | KSh 1,500 – 3,000 | KSh 3,000 – 5,000 | KSh 1,500 – 2,500 |
| 40–43 inch | KSh 2,500 – 4,500 | KSh 4,500 – 7,000 | KSh 1,500 – 3,000 |
| 50–55 inch | KSh 4,000 – 7,000 | KSh 7,000 – 12,000 | KSh 2,000 – 4,000 |
| 65 inch | KSh 6,000 – 10,000 | KSh 10,000 – 18,000 | KSh 2,500 – 5,000 |
Note: Total backlight repair costs (part + labour) typically range from KSh 3,000 to KSh 20,000 depending on screen size and brand. Shops on Luthuli Avenue and in Kirinyaga Road are common sources for strips in Nairobi.
2. OLED Panel (for OLED TVs)
Television OLED Panel: Estimated Prices in Nairobi for Different Sizes and Brands
OLED (Organic Light-Emitting Diode) panels represent the premium tier of television display technology. Unlike LCD/LED sets, each pixel in an OLED screen produces its own light, delivering perfect blacks, infinite contrast, and wide viewing angles. Brands offering OLED TVs in Kenya include LG, Samsung (under the QD-OLED branding), and Sony. Panel replacement is the most expensive repair in the TV industry — in some cases costing more than the TV itself.
Why are OLED panels so expensive? The manufacturing process is complex and yield rates are lower than for standard LCD panels. Additionally, few local suppliers stock OLED panels; most must be sourced from overseas, adding import costs and delays. For this reason, Nairobi repair shops often advise customers to assess whether replacement is economically justified before proceeding.
| Screen Size | Replacement OLED Panel (Part Only) | Estimated Labour |
|---|---|---|
| 48 inch | KSh 60,000 – 100,000 | KSh 5,000 – 10,000 |
| 55 inch | KSh 80,000 – 130,000 | KSh 5,000 – 10,000 |
| 65 inch | KSh 120,000 – 200,000 | KSh 8,000 – 15,000 |
| 77 inch | KSh 180,000 – 300,000+ | KSh 10,000 – 20,000 |
Note: OLED panel prices are highly variable depending on import costs and exchange rates. Most Nairobi shops will source on order — expect 1–3 weeks. For cheaper OLED TVs, panel replacement often exceeds 70% of a new TV’s cost, making replacement questionable.
3. T-Con Board (Timing Controller Board)
Television T-Con Board: Estimated Prices in Nairobi for Different Sizes and Brands
The Timing Controller board — universally called the T-Con board — manages the timing signals between the TV’s main processing board and the display panel. It ensures that pixels refresh correctly and in sync, producing a clear, stable image. When the T-Con board fails, the symptoms are often dramatic: horizontal or vertical coloured lines running across the screen, a half-bright/half-dark display, or a completely blank screen despite the TV powering on. T-Con failures are frequently mistaken for panel damage, but a board swap is far cheaper.
Sourcing in Nairobi: T-Con boards are board-specific; you need the correct part number for your TV model. Shops like Prologic Technologies on Luthuli Avenue and GossTech stock a range of boards for popular brands including Samsung, LG, Hisense, and TCL. If your board is uncommon, it may need to be ordered, typically taking 3–7 days.
| Brand | Estimated T-Con Board Price | Estimated Labour |
|---|---|---|
| Samsung | KSh 5,000 – 12,000 | KSh 1,500 – 3,000 |
| LG | KSh 4,500 – 11,000 | KSh 1,500 – 3,000 |
| Hisense | KSh 4,000 – 9,000 | KSh 1,500 – 2,500 |
| TCL | KSh 3,500 – 8,000 | KSh 1,500 – 2,500 |
| Sony | KSh 6,000 – 15,000 | KSh 2,000 – 4,000 |
Note: T-Con boards typically cost KSh 5,000–12,000 in Nairobi depending on model and brand. Always verify the board part number before purchasing — an incorrect board will not work.
4. Main Board (Motherboard / Main Control Board)
Television Main Board: Estimated Prices in Nairobi for Different Sizes and Brands
The main board (also called the motherboard or main control board) is the brain of the television. It houses the CPU, GPU, and memory, and coordinates every function — processing video signals, running the smart TV operating system, managing HDMI inputs, and driving the audio output. A failed main board can cause a wide range of symptoms: the TV may fail to power on, display a distorted image, lose smart TV functionality, or show an unresponsive menu.
Why main boards fail: Kenya’s inconsistent power supply is a leading cause — voltage spikes and surges destroy sensitive ICs on the main board. This is why surge protectors are strongly recommended for all TVs in Nairobi. Main board replacement is a mid-range repair — cheaper than a screen but more involved than a backlight or T-Con swap.
| Brand | Estimated Main Board Price | Estimated Labour |
|---|---|---|
| Samsung | KSh 8,000 – 20,000 | KSh 2,000 – 4,000 |
| LG | KSh 7,500 – 18,000 | KSh 2,000 – 4,000 |
| Hisense | KSh 6,000 – 15,000 | KSh 1,500 – 3,500 |
| TCL | KSh 5,500 – 13,000 | KSh 1,500 – 3,000 |
| Sony | KSh 10,000 – 22,000 | KSh 2,500 – 5,000 |
Note: Prices depend heavily on whether the board is a Smart TV model (with embedded Android/Google TV) or a basic digital TV board. Smart TV main boards carry a premium of 30–50% over standard boards.
5. Power Supply Board (SMPS)
Television Power Supply Board: Estimated Prices in Nairobi for Different Sizes and Brands
The power supply board (also known as the SMPS — Switched-Mode Power Supply) converts mains alternating current (AC) from the wall socket into the various direct current (DC) voltages needed by the TV’s internal components. It is the component most commonly damaged by unstable electricity — a frequent challenge in many parts of Nairobi. Symptoms of a bad power supply board include the TV failing to turn on, a blinking standby light, random shut-offs, or a clicking sound on startup.
Good news for consumers: Power supply boards are among the more standardised TV components. Compatible replacements are often available even for older or less common models. Capacitor bulging on the PSU board is a tell-tale sign of failure that technicians can often spot visually.
| Brand / Screen Size | Estimated PSU Board Price | Estimated Labour |
|---|---|---|
| 32 inch (any brand) | KSh 3,500 – 7,000 | KSh 1,500 – 2,500 |
| 43 inch (any brand) | KSh 5,000 – 10,000 | KSh 1,500 – 3,000 |
| 55 inch (any brand) | KSh 6,000 – 13,000 | KSh 2,000 – 3,500 |
| 65 inch (any brand) | KSh 8,000 – 15,000 | KSh 2,000 – 4,000 |
Note: Power supply repairs are among the most common TV repairs in Nairobi due to unstable mains electricity. Using a quality surge protector or UPS significantly reduces PSU failure rates.
6. Inverter Board (in Older LED/LCD Sets)
Television Inverter Board: Estimated Prices in Nairobi for Different Sizes and Brands
The inverter board was a critical component in older LCD televisions that used CCFL (Cold Cathode Fluorescent Lamp) backlights rather than LEDs. The inverter converted low DC voltage into the high-frequency AC voltage needed to power those fluorescent tubes. While modern LED TVs do not use inverter boards (they use LED driver boards instead), a large number of older LCD sets from 2008–2015 are still in use across Nairobi households and offices. For these sets, inverter boards remain a relevant spare part.
When does an inverter fail? Symptoms include a dim screen that improves when a torch is shone on it, flickering at startup, or a screen that turns off shortly after switching on. Prologic Technologies and other Luthuli Avenue shops often stock inverters for common older models.
| Screen Size / Model Era | Estimated Inverter Board Price | Estimated Labour |
|---|---|---|
| 32 inch CCFL (pre-2014) | KSh 2,000 – 5,000 | KSh 1,500 – 2,500 |
| 40–42 inch CCFL | KSh 3,000 – 7,000 | KSh 1,500 – 3,000 |
| 46–50 inch CCFL | KSh 4,500 – 9,000 | KSh 2,000 – 3,500 |
| Dual-lamp inverter boards | KSh 5,000 – 12,000 | KSh 2,000 – 4,000 |
Note: As the stock of old CCFL TVs shrinks, inverter boards for rare or obscure models may be difficult to find locally. Technicians may source them from online suppliers, with import lead times of 1–2 weeks.
7. Backlight Driver Board
Television Backlight Driver Board: Estimated Prices in Nairobi for Different Sizes and Brands
The backlight driver board (also called the LED driver board) is found in modern LED-backlit LCD televisions. Its role is to regulate the current and voltage supplied to the LED backlight strips, controlling their brightness and ensuring even illumination across the screen. It is distinct from the power supply board: the PSU converts mains power, while the backlight driver specifically conditions that power for the LED strips. A failed driver board can cause the backlight to be too dim, too bright, unevenly lit, or completely off.
How common is this failure? Backlight driver failures are particularly common in older sets or those used in dusty environments (dust accumulates and causes overheating). It is a moderately priced repair compared to panel or main board replacement.
| Brand | Estimated Driver Board Price | Estimated Labour |
|---|---|---|
| Samsung | KSh 4,000 – 10,000 | KSh 1,500 – 3,000 |
| LG | KSh 3,500 – 9,000 | KSh 1,500 – 3,000 |
| Hisense | KSh 3,000 – 7,000 | KSh 1,500 – 2,500 |
| TCL | KSh 2,500 – 6,500 | KSh 1,500 – 2,500 |
| Sony | KSh 5,000 – 12,000 | KSh 2,000 – 3,500 |
Note: In many TVs the backlight driver circuitry is integrated into the power supply board, meaning both are replaced together. Always have a technician diagnose whether the fault is the driver or the PSU before ordering parts.
8. Tuner Board (RF Tuner)
Television Tuner Board: Estimated Prices in Nairobi for Different Sizes and Brands
The tuner board (also called the RF tuner or demodulator board) is the component responsible for receiving over-the-air broadcast signals — either analogue (in very old sets) or digital (DVB-T2 in Kenya’s current broadcasting standard). It tunes into the transmitted frequency and decodes the signal into audio and video that the TV can display. In smart TVs, the tuner is typically integrated into the main board rather than being a separate module, but in older and mid-range sets it is a standalone replaceable board.
When does a tuner fail? Symptoms include inability to scan channels, poor signal quality even with a functioning aerial, or complete loss of broadcast reception while other inputs (HDMI, USB) work fine. Given Kenya’s full transition to digital terrestrial television, DVB-T2 compatible tuners are the ones now in demand.
| Type | Estimated Tuner Board Price | Estimated Labour |
|---|---|---|
| DVB-T2 standalone tuner board | KSh 2,000 – 6,000 | KSh 1,000 – 2,500 |
| Integrated (brand-specific module) | KSh 4,000 – 10,000 | KSh 1,500 – 3,000 |
| External set-top box (alternative) | KSh 2,500 – 5,000 | — |
Note: In many cases, a faulty TV tuner is more economically replaced by pairing the TV with an affordable external DVB-T2 set-top box rather than sourcing a specific internal tuner board. This is often the faster and cheaper solution in Nairobi.
9. Wi-Fi / Bluetooth Module
Television Wi-Fi / Bluetooth Module: Estimated Prices in Nairobi for Different Sizes and Brands
The Wi-Fi/Bluetooth module is a small daughter board or integrated chip that enables a smart TV to connect wirelessly to home networks, stream online content, and pair with Bluetooth accessories such as soundbars, headphones, or game controllers. In most modern smart TVs this module is either soldered to the main board or connected via a small internal antenna cable. Failure manifests as inability to detect Wi-Fi networks, frequent disconnection, or Bluetooth pairing problems.
Sourcing in Nairobi: Wi-Fi modules are highly model-specific. Generic modules exist but may require firmware modification to work correctly. Brand-specific modules ordered via Luthuli Avenue shops or online (Jiji, Jumia) typically give more reliable results.
| Brand | Estimated Wi-Fi / BT Module Price | Estimated Labour |
|---|---|---|
| Samsung | KSh 3,000 – 8,000 | KSh 1,000 – 2,500 |
| LG | KSh 2,500 – 7,000 | KSh 1,000 – 2,500 |
| Hisense | KSh 2,000 – 5,500 | KSh 1,000 – 2,000 |
| TCL | KSh 1,500 – 5,000 | KSh 1,000 – 2,000 |
| Generic compatible module | KSh 1,000 – 3,000 | KSh 1,000 – 2,000 |
Note: Before replacing a Wi-Fi module, try a factory reset and software update — some connectivity issues are software-related and do not require a hardware fix.
10. Sound / Audio Board
Television Sound / Audio Board: Estimated Prices in Nairobi for Different Sizes and Brands
The audio board (or sound board) processes and amplifies audio signals before sending them to the TV’s built-in speakers. In many TV designs the audio amplification circuitry is built into the main board, but in larger or premium models it is a dedicated board — sometimes called an audio amp board or speaker amplifier board. When this board fails, symptoms include no sound, distorted or crackling audio, intermittent sound loss, or an imbalance between left and right channels.
Diagnosis first: Audio problems can also originate from blown speakers, faulty cables, or software/settings issues — technicians should rule these out before replacing the audio board, which saves unnecessary expense.
| Brand | Estimated Audio Board Price | Estimated Labour |
|---|---|---|
| Samsung | KSh 3,500 – 9,000 | KSh 1,500 – 3,000 |
| LG | KSh 3,000 – 8,000 | KSh 1,500 – 3,000 |
| Hisense | KSh 2,500 – 6,500 | KSh 1,000 – 2,500 |
| TCL | KSh 2,000 – 6,000 | KSh 1,000 – 2,500 |
| Sony | KSh 4,000 – 10,000 | KSh 1,500 – 3,500 |
Note: Many TV speakers (sold as a pair) are available separately for KSh 2,000–6,000. If the audio board is fine but speakers are blown, replacing speakers alone is the more economical solution.
11. HDMI Board / HDMI Input Board
Television HDMI Board: Estimated Prices in Nairobi for Different Sizes and Brands
The HDMI board (or HDMI input board) manages the TV’s High-Definition Multimedia Interface ports — the connections used for gaming consoles, streaming devices, laptops, Blu-ray players, and decoders. In many TVs the HDMI ports are soldered directly onto the main board, meaning damage to a port can affect the entire board. In some designs, especially larger or higher-end models, HDMI connectivity is on a dedicated sub-board that can be replaced independently.
Common causes of HDMI failure: Physical damage from frequent plug/unplug cycles, a bent pin inside the port, or lightning-induced power surges through connected devices. Nairobi’s variable power supply means surge protection is especially important for HDMI-connected devices.
| Repair Type | Estimated Cost (Part) | Estimated Labour |
|---|---|---|
| Single HDMI port re-soldering | KSh 500 – 1,500 | KSh 1,000 – 2,000 |
| HDMI port replacement (hardware) | KSh 1,000 – 3,500 | KSh 1,000 – 2,500 |
| Dedicated HDMI sub-board (where applicable) | KSh 3,000 – 8,000 | KSh 1,500 – 3,000 |
| Main board replacement (if HDMI is integrated) | KSh 7,000 – 20,000 | KSh 2,000 – 4,000 |
Note: Minor repairs such as replacing a single HDMI port typically range from KSh 1,500 to KSh 4,000 inclusive of labour, making it one of the more affordable TV repairs in Nairobi.
12. USB Board
Television USB Board: Estimated Prices in Nairobi for Different Sizes and Brands
The USB board houses the TV’s USB ports, which are used for connecting flash drives, external hard drives, keyboards, and — in some models — for charging mobile devices. Like HDMI ports, USB ports can be mounted on the main board or on a separate sub-board. Physical damage (bent ports, broken solder joints), or detection failures (the TV not recognising connected devices) are the most common complaints.
Practical tip for Nairobi users: USB failure is sometimes caused by power fluctuations damaging the USB controller chip rather than the port itself. This is a common scenario in areas with unstable power. A technician should test with a known-good flash drive before dismantling the set.
| Repair Type | Estimated Cost (Part) | Estimated Labour |
|---|---|---|
| USB port re-soldering | KSh 300 – 1,000 | KSh 800 – 1,500 |
| USB port replacement (hardware) | KSh 500 – 2,000 | KSh 1,000 – 2,000 |
| Dedicated USB sub-board | KSh 2,000 – 6,000 | KSh 1,000 – 2,500 |
| Main board (if USB is integrated) | KSh 7,000 – 20,000 | KSh 2,000 – 4,000 |
Note: USB board repairs are among the minor, more affordable TV repairs — typically KSh 1,500 to KSh 4,000 inclusive of labour in most Nairobi workshops.
13. Display Port / Video Input Board
Television Display Port / Video Input Board: Estimated Prices in Nairobi
The video input board (sometimes called the AV board, display port board, or signal input board) manages the various video input connections on a TV beyond HDMI — including composite AV (red/white/yellow RCA), component video (YPbPr), VGA, and in professional/commercial TV installations, DisplayPort. While newer consumer TVs have largely standardised on HDMI and dropped legacy video inputs, many older sets in Nairobi households and offices still use RCA or VGA connections for connecting DVD players, satellite decoders, or computers.
| Repair / Part Type | Estimated Cost (Part) | Estimated Labour |
|---|---|---|
| AV (RCA) port re-soldering | KSh 300 – 1,200 | KSh 800 – 1,500 |
| Dedicated AV input board | KSh 2,500 – 7,000 | KSh 1,000 – 2,500 |
| VGA input board/module | KSh 2,000 – 6,000 | KSh 1,000 – 2,500 |
| Combined input sub-board (HDMI/AV/USB) | KSh 4,000 – 10,000 | KSh 1,500 – 3,500 |
Note: For TVs lacking a VGA or composite input, an affordable HDMI-to-VGA adapter (KSh 500–1,500) is often a simpler workaround than replacing an internal board.
14. Remote Control Receiver (IR Receiver / IR Sensor)
Television IR Receiver / Remote Control Sensor: Estimated Prices in Nairobi
The infrared (IR) receiver — sometimes called the IR sensor board or remote control receiver — is the small component that detects signals from the TV remote control. It typically sits behind a small window in the TV’s front bezel. When it fails, the remote stops working even with fresh batteries. In some cases the entire front panel board (which includes the sensor, standby LED, and manual control buttons) needs replacement.
Quick diagnosis: Before replacing the IR sensor, test the remote by pointing it at a smartphone camera — if you see a faint purple/white flash on the camera screen when pressing remote buttons, the remote is fine and the sensor is the likely culprit. If there is no flash, replace the remote first (KSh 500–2,000) — it’s cheaper.
| Component | Estimated Price | Estimated Labour |
|---|---|---|
| IR sensor (discrete component) | KSh 150 – 500 | KSh 800 – 1,500 |
| IR receiver / front panel board | KSh 1,500 – 5,000 | KSh 1,000 – 2,000 |
| Universal replacement remote | KSh 500 – 1,500 | — |
| Brand OEM remote control | KSh 1,500 – 4,000 | — |
Note: The IR sensor itself is one of the cheapest TV components, priced as low as KSh 150 for the discrete part. The front panel board that carries it costs more — KSh 1,500 to 5,000 — but is still a modest repair.
15. Microprocessor / CPU Chip
Television Microprocessor / CPU Chip: Estimated Prices in Nairobi
The microprocessor (CPU) is the central processing unit of the television’s main board — it runs the smart TV operating system, processes video and audio decoding, manages app execution, and coordinates all functions. In modern smart TVs it is a highly integrated System-on-Chip (SoC) that also includes a GPU and media processing engine. CPU chips are surface-mount components soldered directly onto the main board, meaning they cannot be replaced individually in most Nairobi repair scenarios — a failing CPU effectively means main board replacement.
When is chip-level repair possible? A small number of specialised electronics repair workshops in Nairobi (mainly around Luthuli Avenue and River Road) offer BGA (Ball Grid Array) reballing and chip-level repair services for main boards. This is skilled work requiring hot air rework stations and is priced accordingly.
| Service / Component | Estimated Price |
|---|---|
| BGA chip reballing / reflowing (service) | KSh 3,000 – 8,000 |
| CPU SoC replacement (chip sourced separately, if available) | KSh 5,000 – 20,000 |
| Full main board replacement (more common solution) | KSh 7,000 – 22,000 |
| Chip-level diagnostic fee | KSh 1,500 – 3,500 |
Note: CPU replacement as a discrete operation is rare in the Nairobi market. Most technicians recommend main board replacement as the more reliable and cost-predictable solution when the CPU is confirmed faulty.
16. Memory (RAM / DDR Memory)
Television RAM / DDR Memory: Estimated Prices in Nairobi
Smart televisions contain onboard RAM (Random Access Memory) — typically DDR3 or DDR4 — that supports the CPU in running the operating system, apps, and video buffering. In most TVs this RAM is soldered directly onto the main board (unlike PC RAM which is removable). Standalone TV RAM replacement is therefore not a common retail service; instead, it is addressed through main board replacement or, in chip-level repair shops, through BGA-level rework.
For reference, computer DDR RAM (sold separately for PCs and laptops in Nairobi) provides a useful price benchmark for the component value.
| Memory Type | Capacity | Estimated Price in Nairobi (PC/standalone module) |
|---|---|---|
| DDR3 SO-DIMM (laptop/reference) | 4 GB | KSh 1,500 – 3,000 |
| DDR4 SO-DIMM (laptop/reference) | 8 GB | KSh 2,500 – 5,000 |
| DDR4 DIMM (desktop/reference) | 8 GB | KSh 2,000 – 4,000 |
| TV onboard RAM (chip-level replacement, service) | As fitted | KSh 4,000 – 12,000 |
Note: Retailers including Glantix (Moi Avenue), Almiria Techstore, and Lansotech Solutions in Nairobi stock PC RAM. For TV-specific memory repairs, a chip-level technician is required — this is a niche service not widely available.
17. Flash Memory / eMMC Storage
Television Flash Memory / eMMC Storage: Estimated Prices in Nairobi
Smart televisions store their operating system, apps, and user settings in onboard flash memory — typically eMMC (Embedded MultiMediaCard) chips soldered onto the main board. When eMMC memory fails or becomes corrupted, the TV may fail to boot, get stuck on the startup screen, show error messages, or repeatedly restart. This is a less common but frustrating failure mode.
Repair options in Nairobi: A small number of board-level repair specialists can rework eMMC chips — reading the corrupted chip, reflashing firmware, or replacing the chip entirely. This is highly skilled work. The more common solution is main board replacement. Standalone eMMC chips (for repair purposes) are available from component dealers.
| Component / Service | Estimated Price |
|---|---|
| eMMC chip (generic, 8–32 GB, sourced from component dealer) | KSh 500 – 2,500 |
| eMMC reflashing / firmware service | KSh 2,000 – 6,000 |
| eMMC chip replacement (component + BGA labour) | KSh 5,000 – 12,000 |
| Full main board replacement (alternative) | KSh 7,000 – 22,000 |
Note: eMMC failure sometimes mimics software problems. Before committing to hardware repair, a factory reset or firmware re-flash (if the TV allows it via USB) should be attempted first — this is free.
18. Oscillator / Crystal
Television Oscillator / Crystal: Estimated Prices in Nairobi
Oscillators and crystal resonators are tiny components that generate precise clock frequencies used by the TV’s circuits for timing and synchronisation. Every digital circuit in a television — the main processor, the T-Con board, the tuner — relies on clock signals derived from oscillators. They are passive, highly reliable components that rarely fail under normal conditions. When they do fail (often after a lightning strike or severe power surge), they cause the TV to malfunction at a fundamental level — freezing, failing to boot, or producing garbled output.
Where to buy in Nairobi: Oscillators and crystals are stocked by electronics component suppliers including Nerokas (online, based in Nairobi), Ktechnics, and shops on River Road. They are very low-cost components.
| Component Type | Frequency Range | Estimated Price (per unit) |
|---|---|---|
| Crystal resonator (through-hole) | 4 MHz – 50 MHz | KSh 30 – 150 |
| SMD crystal oscillator | 8 MHz – 100 MHz | KSh 50 – 300 |
| TCXO (Temperature-compensated) | Various | KSh 200 – 800 |
| Crystal replacement service (labour) | — | KSh 500 – 2,000 |
Note: The component itself is inexpensive, but identifying which oscillator has failed requires an oscilloscope and skilled diagnostics. Labour dominates the total cost of this repair.
19. Capacitors
Television Capacitors: Estimated Prices in Nairobi for TV Repair
Capacitors are among the most common failure points in television electronics — particularly electrolytic capacitors on the power supply board, which are stressed by heat and voltage fluctuations. A swollen, leaking, or open capacitor causes a wide range of TV symptoms: failure to power on, shutdowns, screen flickering, or audio distortion. Capacitor replacement (called “recapping”) is one of the most cost-effective TV repairs available and is offered by most electronics technicians in Nairobi.
Where to buy: Capacitors are stocked by Nerokas, Ktechnics, Universal Tech Electronics, and numerous component shops along River Road and Kirinyaga Road. They are sold individually or in packs.
| Capacitor Type | Typical Value / Rating | Estimated Price (per unit) |
|---|---|---|
| Electrolytic (general purpose) | 10 µF – 1000 µF / 6.3V–50V | KSh 10 – 80 |
| High-voltage electrolytic (PSU) | 100 µF – 470 µF / 200V–450V | KSh 50 – 250 |
| Ceramic disc capacitor | 10 pF – 100 nF | KSh 5 – 30 |
| Film / polyester capacitor | 100 nF – 10 µF | KSh 20 – 100 |
| SMD capacitor (pack of 10) | Various | KSh 50 – 300 |
| Full PSU recapping service (labour + parts) | — | KSh 1,500 – 5,000 |
Note: Capacitor failure — particularly bulging electrolytics — is visible to the naked eye. If a technician spots bulged caps on a PSU board, recapping the entire board (not just the faulty ones) is advisable, as the others will likely follow.
20. Resistors
Television Resistors: Estimated Prices in Nairobi for TV Repair
Resistors are passive components that limit or regulate electrical current flow within a circuit. In television electronics, they appear throughout the power supply, audio amplifier, and signal processing sections of the board. While individual resistors are extremely reliable and rarely fail on their own, they can burn open or change value when subjected to overcurrent conditions — usually following a more catastrophic failure event such as a power surge. Identifying a failed resistor requires a multimeter and some electronics knowledge.
Where to buy in Nairobi: Resistors are widely available at Nerokas, Ktechnics, Universal Tech Electronics, and component stalls in River Road and Kirinyaga Road markets. They are sold per piece or in assorted packs.
| Resistor Type | Power Rating | Estimated Price (per unit / per pack) |
|---|---|---|
| Carbon film resistor (1/4 W) | 0.25 W | KSh 5 – 15 per piece |
| Metal film resistor (1/4 W, 1% tolerance) | 0.25 W | KSh 10 – 30 per piece |
| Carbon film (1/2 W) | 0.5 W | KSh 10 – 25 per piece |
| Wirewound resistor (power) | 2 W – 10 W | KSh 30 – 150 per piece |
| SMD resistor (0805, pack of 10) | 0.125 W | KSh 20 – 80 per pack |
| Assorted resistor kit (100–500 pcs) | Various | KSh 300 – 1,200 |
Note: Resistors are among the cheapest electronic components available in Nairobi. The cost of resistor repair is dominated entirely by the technician’s diagnostic and labour time rather than the component price.
21. Diodes
Television Diodes: Estimated Prices in Nairobi for TV Repair
Diodes are semiconductor components that allow electrical current to flow in one direction only. In television circuitry they serve several critical roles: rectifier diodes convert AC to DC in the power supply, zener diodes regulate voltage levels, and Schottky diodes provide fast switching in power circuits. Diode failure — usually a short circuit caused by overcurrent — is a common consequence of power surge damage and typically causes the power supply board to fail. Replacement is a straightforward but skilled repair.
Identification tip: Diode types are marked with a part number on the component body. Common TV rectifier diodes (e.g. 1N4007, FR107, UF4007) are inexpensive and widely available. High-voltage diodes used in flyback circuits are more specialised.
| Diode Type | Application | Estimated Price (per unit) |
|---|---|---|
| 1N4007 rectifier diode | PSU rectification | KSh 10 – 30 |
| 1N5408 (3A rectifier) | Higher current PSU | KSh 15 – 50 |
| Zener diode (various voltage) | Voltage regulation | KSh 15 – 60 |
| Schottky diode (1N5819, SR540) | Fast switching PSU | KSh 20 – 80 |
| High-voltage diode (HER308, UF4007) | SMPS circuits | KSh 20 – 100 |
| Bridge rectifier module | PSU AC rectification | KSh 50 – 300 |
Note: Diodes are very cheap components — typically KSh 10–100 each. As with resistors, the diagnostic and labour cost far exceeds the part cost.
22. Transistors
Television Transistors: Estimated Prices in Nairobi for TV Repair
Transistors are semiconductor devices used for switching and amplification in television circuits. In TV power supply boards, power transistors (including MOSFETs and bipolar junction transistors) handle high-current switching in the SMPS circuit. In audio sections, transistors amplify audio signals. When a power transistor fails (commonly a short-circuit failure caused by a power surge), it often takes out other nearby components — including fuses and resistors — making diagnosis important before ordering parts.
Types found in TVs: The most common are NPN/PNP BJTs (e.g. 2SC, 2SA series), N-channel and P-channel MOSFETs, and IGBT transistors in larger high-power circuits. Nairobi’s Nerokas and River Road component shops stock a range of common types.
| Transistor Type | Common Part Numbers | Estimated Price (per unit) |
|---|---|---|
| Small-signal BJT (NPN/PNP) | BC547, 2N2222, 2N3904 | KSh 15 – 50 |
| Medium-power BJT | TIP31, TIP41, MJE340 | KSh 30 – 120 |
| Power MOSFET (N-channel) | IRF840, FQP8N60, K2961 | KSh 80 – 350 |
| Power MOSFET (P-channel, switching) | IRF9540, FQP17P06 | KSh 80 – 300 |
| Darlington transistor | TIP122, TIP142 | KSh 50 – 150 |
| SMD transistor pack (assorted) | Various | KSh 150 – 600 |
Note: Power transistors in the SMPS section are among the most surge-vulnerable components in a TV. When a power transistor fails, always check the gate resistor and fuse — they often fail together.
23. Inductors / Coils
Television Inductors / Coils: Estimated Prices in Nairobi for TV Repair
Inductors (also called coils or chokes) are passive electronic components that store energy in a magnetic field and filter electrical signals. In television power supply boards, inductors play a key role in the SMPS circuit — filtering output voltages, reducing electrical noise, and regulating energy delivery to downstream components. Common failure modes include open-circuit winding (often caused by overcurrent) or core saturation. A failed inductor in the PSU often causes the TV to fail to start or to output incorrect voltages.
Identification: Inductors are typically cylindrical or toroidal (donut-shaped) components wound with copper wire. Their value is measured in henries (H) or millihenries (mH) and is usually printed or stamped on the component body. Nerokas in Nairobi stocks a range of inductors for electronics repair.
| Inductor Type | Inductance Range | Estimated Price (per unit) |
|---|---|---|
| Axial lead inductor (through-hole) | 1 µH – 100 µH | KSh 20 – 80 |
| Toroidal ferrite core inductor | 10 µH – 10 mH | KSh 50 – 300 |
| SMD power inductor | 1 µH – 220 µH | KSh 30 – 200 |
| Common-mode choke (filter coil) | Various | KSh 100 – 500 |
| Custom wound replacement coil (service) | — | KSh 500 – 2,000 |
Note: Inductors are low-cost components available from electronics component suppliers in Nairobi. As with most passive components, the technician’s diagnostic and rework time is the primary cost driver.
24. Fuses
Television Fuses: Estimated Prices in Nairobi for TV Repair
Fuses are the first line of defence in a television’s electrical circuit — they are designed to break the circuit and sacrifice themselves when current exceeds a safe level, protecting more expensive downstream components. In TVs, fuses are found on the power supply board (main board fuse), inside the mains inlet section, and sometimes on the backlight driver. A blown fuse is often the first sign of a power surge event. Fuses are among the cheapest TV components to replace but require exact specification matching.
Important: Never replace a fuse with a higher-rated one or bypass it with wire. A fuse rated for your TV’s circuit is a safety critical component — using the wrong rating risks fire or permanent damage to expensive boards.
| Fuse Type | Common Ratings for TVs | Estimated Price (per unit) |
|---|---|---|
| Glass tube fuse (5 × 20 mm) | 1A, 2A, 3.15A, 5A / 250V | KSh 20 – 80 |
| Ceramic tube fuse (6.3 × 32 mm) | 5A – 20A / 250V | KSh 30 – 120 |
| SMD fuse (surface mount) | 0.5A – 5A | KSh 30 – 100 |
| Fuse holder (panel mount) | — | KSh 50 – 200 |
| Assorted fuse pack (10–20 pcs) | Mixed ratings | KSh 100 – 400 |
Note: Fuses are available from virtually every electronics shop in Nairobi including Nerokas, Universal Tech Electronics, and component dealers in River Road. Always bring the blown fuse for exact matching.
25. Rectifiers
Television Rectifiers: Estimated Prices in Nairobi for TV Repair
Rectifiers — specifically bridge rectifiers or full-wave rectifier diode modules — convert the incoming alternating current (AC) from the mains supply into direct current (DC) within the TV’s power supply board. This is the very first stage of power conversion inside the TV. Rectifier failure is typically caused by overvoltage events, lightning surges, or long-term thermal stress. A faulty rectifier causes the TV to be completely dead (no power at all) or to blow fuses repeatedly.
Bridge rectifier modules package four diodes in a single block, simplifying replacement compared to replacing individual diodes. They are widely available in Nairobi’s electronics component shops.
| Rectifier Type | Current / Voltage Rating | Estimated Price (per unit) |
|---|---|---|
| Bridge rectifier module (GBU/GBL series) | 4A–10A / 400V–600V | KSh 50 – 250 |
| High-current bridge rectifier | 15A–35A / 400V–800V | KSh 150 – 600 |
| Single rectifier diode (1N4007, 1N5408) | 1A–3A / 1000V | KSh 10 – 50 |
| Fast recovery rectifier (FR107, UF4007) | 1A / 1000V | KSh 20 – 80 |
| Schottky rectifier (SR540, MBR1545) | 5A–15A / 40V–45V | KSh 30 – 150 |
Note: Rectifiers are inexpensive and widely available. Labour for rectifier replacement (including desoldering from the PSU board and resoldering the new component) is typically KSh 500–2,000.
26. Heat Sinks
Television Heat Sinks: Estimated Prices in Nairobi for TV Repair
Heat sinks are passive metal components — usually made from aluminium or copper — that absorb and dissipate heat away from power-generating components such as transistors, voltage regulators, and MOSFET switches on the power supply board. Without adequate heat sinking, these components overheat and fail prematurely. In Nairobi’s warm climate, effective heat dissipation is especially important for TV longevity. Heat sink failure is usually evident as overheating-related TV shutdowns.
When are heat sinks replaced? Heat sinks themselves rarely fail — more commonly, the thermal interface material (thermal paste or thermal pad) between the heat sink and the component dries out and loses effectiveness. Re-applying fresh thermal paste is a cheap preventive measure.
| Component | Estimated Price |
|---|---|
| Small aluminium heat sink (TO-220 transistor size) | KSh 50 – 200 |
| Medium heat sink (for SMPS MOSFETs) | KSh 150 – 600 |
| Thermal paste (per tube / syringe) | KSh 100 – 500 |
| Thermal pad (sheet, 10 × 10 cm) | KSh 100 – 400 |
| Heat sink compound application (service) | KSh 500 – 1,500 |
| Custom/large heat sink assembly | KSh 500 – 2,000 |
Note: Thermal paste and small heat sinks are available from electronics component dealers in Nairobi including Nerokas and suppliers in River Road. For common transistor packages (TO-220, TO-247), stock heat sinks are readily available.
27. Cooling Fans (in Some Models)
Television Cooling Fan: Estimated Prices in Nairobi for TV Repair
While most LCD/LED televisions are passively cooled (relying on convection through ventilation slots), some models — particularly larger high-brightness sets, OLED TVs, and commercial displays — include internal DC cooling fans to manage heat from the power supply or panel driver circuits. When a fan fails or becomes noisy, the TV may display a warning, reduce brightness, or shut down automatically as a thermal protection measure.
Where to source in Nairobi: DC cooling fans for electronics (5V, 12V, and 24V variants) are available from Nerokas, electronics suppliers in Kirinyaga Road, and computer hardware shops. Fan size (typically 40 mm, 60 mm, or 80 mm for TVs) and voltage rating must be matched exactly.
| Fan Size / Type | Voltage | Estimated Price |
|---|---|---|
| 40 mm DC fan | 5V or 12V | KSh 200 – 600 |
| 60 mm DC fan | 12V | KSh 300 – 900 |
| 80 mm DC fan | 12V | KSh 400 – 1,200 |
| Fan connector / wiring harness | — | KSh 100 – 400 |
| Fan installation (labour) | — | KSh 500 – 1,500 |
Note: TV cooling fans are relatively uncommon parts in the Nairobi repair market (since most consumer TVs don’t use them), but 12V DC fans sold for computer cooling are often compatible and widely available.
28. Shielding Covers / Metal Shields
Television Shielding Covers / Metal Shields: Estimated Prices in Nairobi
Metal shielding covers (also called EMI shields or RF shields) are pressed metal enclosures fitted over sensitive circuit sections on the main board and tuner board to prevent electromagnetic interference (EMI) from corrupting signal processing. They are not components that typically fail but may be damaged during a poorly executed repair, physically bent, or lost during disassembly. Missing or damaged shields can lead to picture noise, interference, or RF reception problems.
Availability in Nairobi: Specific OEM metal shields for a given TV model are rarely stocked as standalone spares in Nairobi. They are more commonly sourced from donor boards (damaged TVs of the same model) or ordered online. Generic EMI shielding tape and aluminium foil tape are available as workarounds.
| Item | Estimated Price |
|---|---|
| EMI shielding tape (copper or aluminium, per roll) | KSh 300 – 1,000 |
| Generic press-fit EMI shield (assorted) | KSh 200 – 800 |
| OEM-specific shield (sourced from donor board) | KSh 500 – 2,500 |
| Conductive foam gasket / strip | KSh 150 – 600 |
Note: Shielding covers are rarely replaced as a standalone service. They more commonly need attention after another repair is performed. If you suspect missing shielding is causing interference, an experienced technician can fabricate a replacement from sheet metal.
29. Screen and Mechanical Parts
Television Screen and Mechanical Parts: Estimated Prices in Nairobi
Beyond the electronic boards, televisions contain a range of mechanical parts — stands, hinges, back covers, cable management clips, internal frames, speaker grilles, and mounting brackets — that may need replacement after physical damage, accidental drops, or rough handling during transport. These are often overlooked but important for safe TV operation and presentation.
The most significant mechanical part is the display panel itself (the screen), which is the single most expensive TV component and is discussed in earlier articles. Other mechanical parts are generally more affordable and easier to source.
| Mechanical Part | Estimated Price |
|---|---|
| TV stand / base (compatible replacement) | KSh 1,000 – 5,000 |
| VESA wall mount bracket (universal, 14″–55″) | KSh 1,500 – 4,000 |
| VESA wall mount bracket (heavy-duty, 55″–85″) | KSh 3,000 – 8,000 |
| Back cover / rear housing (OEM or compatible) | KSh 2,000 – 8,000 |
| Internal chassis / frame (model-specific) | KSh 3,000 – 12,000 |
| Cable management clips / ribbon cables | KSh 100 – 800 |
| Speaker grille cover (clip-on) | KSh 300 – 1,500 |
Note: TV stands and wall mounts are readily available at electronics shops and hardware stores across Nairobi. OEM rear covers and internal frames are harder to source and may need to be ordered from overseas suppliers.
30. Front Glass / Bezel
Television Front Glass / Bezel: Estimated Prices in Nairobi
The front glass (also called the protective glass panel or cover glass) is a clear protective layer that sits in front of the actual LCD/LED display panel. The bezel is the plastic or metal frame that surrounds the screen and holds the front glass in place. Both are primarily cosmetic/protective components but damaged bezels can expose internal components to dust and moisture, while a cracked cover glass can make the screen difficult to view (though the panel underneath may remain functional).
Important distinction: The cover glass is separate from the actual display panel. A cracked cover glass does not necessarily mean the LCD panel is damaged. In some cases, replacing only the cover glass is sufficient and significantly cheaper than a full panel replacement.
| Component | Screen Size | Estimated Price |
|---|---|---|
| Replacement bezel (plastic front frame) | 32 inch | KSh 1,500 – 4,000 |
| Replacement bezel (plastic front frame) | 43–55 inch | KSh 2,500 – 7,000 |
| Replacement bezel (plastic front frame) | 65 inch+ | KSh 4,000 – 12,000 |
| Cover / protective glass panel | 32–43 inch | KSh 2,000 – 6,000 |
| Cover / protective glass panel | 50–65 inch | KSh 4,000 – 12,000 |
| Bezel / glass installation (labour) | Any size | KSh 1,000 – 3,000 |
| TV protective guard / shield (alternative) | 32–65 inch | KSh 2,000 – 8,000 |
Note: OEM bezels for specific TV models are not commonly stocked in Nairobi. Compatible or donor-board bezels are more readily available. Prologic Technologies on Luthuli Avenue and TV Repair Kenya are among the shops where bezel replacements can be sourced or ordered.
