Television Repair Services in Nairobi by Silicon Electronics: The Complete Guide
If your television has stopped working, the last thing you want is to spend weeks without it — or worse, pay for a brand-new set when a professional repair would cost a fraction of the price. Silicon Electronics, located at Kang’ari Building on Luthuli Avenue in Nairobi, offers one of the most comprehensive television repair services in Kenya. From cracked screens and power failures to smart TV software issues and full motherboard diagnostics, their certified technicians handle every fault across every brand.
This guide walks through each service category in detail, so you know exactly what to expect — and what it is likely to cost — before you pick up the phone.
1. Screen and Display Repair
The screen is the most expensive component in any modern television, and it is also the most exposed to damage. Silicon Electronics offers the full spectrum of screen and display repairs for LED, LCD, OLED, and QLED panels.
Cracked or physically damaged screen replacement is the most common screen repair request. A fallen remote, a knock from a child’s toy, or accidental impact can shatter the panel entirely. The team sources matching replacement panels for all major brands and sizes.
Dead pixels and pixel line correction addresses the frustrating rows or isolated dots of fixed colour that appear on the display. These can result from manufacturing defects, physical pressure, or age-related degradation.
Flickering, dim, or fading picture repair is typically caused by ageing backlight strips, failing capacitors, or unstable power supply to the display driver circuits — all addressable without replacing the entire panel.
Vertical or horizontal lines on screen are one of the most recognisable faults on LCD and LED televisions. They are usually caused by a damaged T-Con board connection, a failing panel ribbon cable, or a faulty display driver IC.
Backlight failure and LED strip replacement handles the scenario where the TV appears to power on — sound is present, the standby light functions — but the picture is completely dark or barely visible when a torch is shone at the screen. This is nearly always a backlight fault.
Colour distortion, tint, and picture calibration corrects problems such as a pink, green, or yellow cast over the image, often the result of a failing main board, damaged ribbon cables, or incorrect settings drifted over time.
Image retention and burn-in mitigation (OLED/Plasma) addresses the ghost images that can persist on OLED and plasma screens after prolonged static content display. Silicon Electronics applies pixel refresh cycles and software-level mitigation techniques to reduce visible burn-in.
2. Power and Startup Repair
Power faults are the second most common television complaint in Nairobi, particularly due to the region’s unstable electricity supply and frequent power surges.
TV not turning on (no power) can range from a blown fuse to a completely failed power supply board. The technicians perform a systematic diagnosis before recommending replacement parts.
TV turns on then off (power cycling) — a television that powers on and immediately shuts off is typically suffering from a failing capacitor on the power board, an overheating protection circuit triggering, or a fault on the main board.
Standby light on but no response suggests the power board is delivering low-voltage standby current but cannot initiate a full power-on sequence, pointing to either the main board, firmware, or the T-Con board.
Power board and PSU replacement is carried out when the power supply unit is beyond economical component-level repair, requiring a full board swap.
Fuse, relay, and capacitor replacement is a cost-effective, component-level repair that resolves many power faults without the expense of a complete board replacement.
Power surge and lightning damage repair is especially relevant in Nairobi where power spikes are common. Surge damage can destroy multiple boards simultaneously, and Silicon Electronics carries out multi-board assessment and repair.
3. Audio and Sound Repair
A television with a perfect picture but no sound — or poor audio quality — is hardly usable. The audio repair service covers both internal speaker faults and output-related issues.
No sound with picture present is diagnosed at the main board, audio amplifier circuit, or speaker level. The cause is often a failed audio IC or a disconnected speaker harness.
Distorted, crackling, or intermittent audio typically points to blown speaker cones, failing audio capacitors on the amplifier board, or loose internal connections that worsen with heat.
Low volume or one-side speaker failure indicates either a failed individual speaker driver or a channel-specific fault on the audio amplifier circuit.
Internal speaker replacement involves sourcing and fitting matching speakers for the specific television model, restoring full stereo output.
Audio output and earphone jack issues repair the physical 3.5mm jack or optical audio output port, which can develop faults from regular use or accidental stress on connected cables.
ARC/eARC and soundbar connection problems address compatibility and handshake issues between the television’s HDMI ARC port and external soundbars or audio systems — increasingly common on newer smart televisions.
4. Signal, Input, and Connectivity Repair
With more devices connected to televisions than ever before — decoders, gaming consoles, streaming sticks, DVD players — input and connectivity faults have become one of the most frequently reported issues.
HDMI port repair or replacement addresses bent pins, broken solder joints, or physically damaged HDMI sockets. This is one of the most requested physical repairs at Silicon Electronics.
AV, component, and antenna port issues repair older connection types that are still widely used in Nairobi with legacy decoders and home cinema equipment.
“No signal” or input not detected problems involve diagnosing whether the fault lies in the input hardware, the main board’s signal processing circuit, or a configuration issue within the TV’s menu system.
TV not detecting external devices — a decoder or console that a television refuses to recognise — is solved through port-level repair, firmware updates, or main board diagnosis.
Loose or damaged input sockets are repaired by resoldering or replacing the physical connectors on the main board, preventing further damage from repeated cable insertion.
5. Smart TV and Software Repair
Modern smart televisions run complex operating systems, and software faults are increasingly common — particularly after failed firmware updates or prolonged use.
Firmware upgrade and reinstallation involves loading the correct, verified firmware for the specific television model to resolve software-layer faults without replacing hardware.
Boot loop, stuck on logo, or freezing issues are resolved through firmware reinstallation, flash memory repair, or — in severe cases — eMMC chip replacement at component level.
Smart TV apps not working or crashing can result from insufficient internal storage, corrupted app data, or outdated firmware incompatible with current app versions.
Network and Wi-Fi connection problems are diagnosed at both the hardware level (Wi-Fi module replacement) and the software level (network configuration and firmware repair).
Smart features not working (screen mirroring, casting) are resolved through protocol-level configuration, firmware updates, or Wi-Fi module replacement.
OS corruption and factory reset services restore the television to a clean operating state when software corruption has made the system unstable or unusable.
6. Picture Quality and Colour Calibration
Beyond hardware faults, a television can produce a technically functional but visually poor image. Silicon Electronics offers professional calibration services for viewers who demand the best from their display.
Washed-out or overly dark picture is corrected through backlight intensity adjustment and picture settings optimisation tuned to the specific panel’s characteristics.
Incorrect colour balance or white balance is addressed using calibration instruments and software tools to bring the display in line with the sRGB or DCI-P3 colour standards.
Contrast, brightness, and gamma calibration fine-tunes the tonal response of the display for accurate, pleasing images across a wide range of content types.
Motion blur and judder optimisation adjusts the motion smoothing, backlight scanning, and refresh rate settings to deliver clean, natural motion — particularly important for sports and action content.
Professional ISF/THX-style picture calibration is offered for clients who want a cinema-grade viewing experience, with detailed measurement and verification of the final result.
7. Main Board and Component-Level Repair
Main board repair is where the technical depth of Silicon Electronics’ team is most apparent. Rather than replacing entire boards unnecessarily, the technicians work at component level wherever economically viable.
Main board diagnostics and repair involves systematic fault tracing on the primary control board that coordinates all television functions.
T-Con board repair or replacement addresses display output faults — lines, blank screens, and distorted images — that originate in the timing control board between the main board and the panel.
LVDS cable and connector issues repair the fragile ribbon cables carrying video data from the main board to the panel, which can develop faults from vibration, heat cycling, or physical stress.
BGA reflow and reball on critical ICs uses specialist hot-air rework equipment to address failed solder joints beneath large integrated circuits — a common fault on older Samsung and LG main boards.
Replacement of faulty ICs, resistors, and capacitors resolves specific component failures without the cost of a complete board replacement.
8. Backlight and Inverter Repair
Backlight faults are among the most common reasons a television displays no picture despite being powered on.
LED backlight strip replacement involves opening the panel assembly and replacing the LED strips that illuminate the display from behind, restoring full picture brightness.
CCFL tube and inverter board repair applies to older LCD televisions that used fluorescent tubes rather than LEDs for backlighting — a technology still present in many households across Nairobi.
Uneven lighting, bright spots, or patches are caused by failed individual LEDs within the backlight array and are resolved through strip-level replacement or spot repair.
TV has sound but no picture is the classic backlight failure presentation, and Silicon Electronics resolves this without unnecessary panel replacement in most cases.
9. Remote Control and Control System Repair
A television that cannot be controlled is as frustrating as one that does not work at all.
Remote control repair or replacement covers button failures, IR emitter faults, and battery contact corrosion — as well as full remote replacement where repair is not viable.
IR sensor repair on the TV addresses the infrared receiver built into the television frame, which can fail due to physical damage or component ageing.
Button and control panel faults on the TV frame repair the physical controls on the television’s bezel when they become unresponsive or stuck.
Pairing issues with smart remotes and voice remotes resolve Bluetooth and RF pairing failures with modern remotes that use wireless protocols rather than infrared.
10. Mounting, Installation, and Setup Services
Silicon Electronics goes beyond repair, offering end-to-end installation and setup services across Nairobi.
Wall mounting and bracket installation provides professional fitting of wall brackets for all television sizes, with correct cable management and safety verification.
TV relocation and device reconnection handles the careful disconnection, transportation assistance, and reconnection of your television and all connected devices when moving within Nairobi.
Initial setup and channel tuning configures the television from scratch — channel scanning, input labelling, network connection, and app setup.
Cable management and power protection setup includes surge protector installation and tidy cable routing for a professional finish.
11. Brand- and Technology-Specific Repair
Silicon Electronics services all major television brands available in Kenya, with technicians trained on the specific architecture of each manufacturer’s products.
Supported technologies include LED, LCD, OLED, QLED, Mini-LED, and Plasma. Supported brands include Samsung, LG, Sony, TCL, Hisense, Vitron, Skyworth, Syinix, Itel, and more. Curved and ultra-slim panel handling is also offered, along with legacy 3D TV feature repair where applicable.
12. Preventive Maintenance and Inspection
Prevention is more affordable than cure. Silicon Electronics offers periodic health checks for televisions, particularly useful for older sets or those in dusty environments.
Internal cleaning and dust removal clears accumulated dust from cooling vents, boards, and the panel assembly — a significant cause of overheating faults.
Ventilation and cooling system checks verify that all internal airflow paths are unobstructed and that any cooling fans are functioning correctly.
Surge protection and power conditioning advice helps clients choose the right protection equipment for Nairobi’s power grid conditions.
Periodic health checks and performance testing provide peace of mind that your television is operating within normal parameters.
13. On-Site and Workshop-Based Services
Flexibility is a key part of the Silicon Electronics offer. Not every television can easily be transported to Luthuli Avenue.
In-home diagnosis and repair is offered for large televisions (55 inches and above) where transportation risk outweighs the inconvenience of a home visit.
Carry-in and workshop repairs are available for smaller televisions, with the workshop’s full equipment available for complex component-level work.
Pickup and delivery services collect the television from your home across Nairobi — including Westlands, Kilimani, Karen, Parklands, Gikambura, and surrounding areas — and return it after repair.
Express and same-day repair options are available for common faults such as power board replacement, HDMI port repair, and software resets, subject to parts availability.
