Introduction

If your TV has suddenly gone black, shows distorted images, refuses to power on, or presents repeated errors, the problem may lie with the motherboard. Refitec — Nairobi’s trusted electronics repair brand (0704843613, refitec.co.ke) — offers professional motherboard replacement services for all major TV brands in Lavington and surrounding suburbs. This guide explains what a TV motherboard does, common failure modes, how Refitec diagnoses and replaces motherboards, what to expect during the service, spare parts availability, and a handy list of roads and estates we commonly serve in Lavington.

This page is written for homeowners, landlords, property managers and estate agents in Lavington who want clear, practical information about motherboard replacement: the causes, the process, cost factors, spare parts, and how to get reliable service without losing data or functionality.

What the TV motherboard does (a simple explanation)

The motherboard (also called the main board, logic board or T-con board for some models) is the TV’s central control unit. It manages power distribution, video processing, audio decoding, the smart TV operating system, HDMI/signal inputs, and communication between display components and user interfaces (remote control, buttons, Wi‑Fi, etc.). Consider it the TV’s brain: when it fails many key functions stop working.

Motherboards are responsible for:

• Power sequencing and regulation to other boards (power supply, T-con, LED driver).
• Processing video signals (scaling, deinterlacing, color corrections).
• Running the smart TV OS and apps (on smart sets).
• Managing ports (HDMI, USB, Ethernet) and peripheral control.
• Responding to remote control and front-panel buttons.

Because the motherboard interacts with so many subsystems, a failure can present as many different symptoms — which is why proper diagnostics are important.

Common symptoms that point to motherboard failure

Not every TV fault means the motherboard is dead. But these problems commonly indicate motherboard issues:

1. TV won’t power on but standby light blinks or shows unusual behaviour — often motherboard or power regulation faults.
2. No picture but you have sound — video processing or backlight control signals from the main board may be failing.
3. Black screen with a faint image visible under bright light — often T-con or mainboard video processing failure.
4. TV boots but freezes on manufacturer logo or Android/Smart TV splash screen — firmware or OS corruption on the main board.
5. Random reboots, crashes or freezing — overheating, failing capacitors, or damaged flash memory on the motherboard.
6. No HDMI or USB detection — port controller or firmware on the main board.
7. Smart features not loading, Wi-Fi/Bluetooth not working — integrated network modules on the main board.
8. Error codes on screen (E01, E02 etc.) — many codes point to mainboard issues depending on the brand.

What causes motherboard failure?

Motherboard problems arise from a mix of electrical, environmental, mechanical and software factors:

• Power surges and unstable electricity: sudden spikes can blow voltage regulators, MOSFETs or corrupt firmware.
• Age and component wear: electrolytic capacitors dry out, solder joints crack (especially on regularly heated components), and ICs can fail over time.
• Overheating: poor ventilation or blocked vents cause thermal stress leading to failure.
• Water or moisture ingress: humidity or accidental spills corrode traces and connectors.
• Physical shock: dropping the TV or impact to the chassis can fracture solder joints or damage components.
• Manufacturing defects or firmware bugs: occasionally a design flaw causes recurring failures in a particular model.
• Incompatible firmware updates or interrupted updates: firmware corruption can render the board unbootable.

Understanding the root cause helps Refitec advise whether repair (component-level) or replacement (swap the entire motherboard) is the most reliable and cost‑effective option.

Diagnosis: how Refitec tests the problem

Refitec follows a structured diagnostic process to identify whether the motherboard is the fault and whether a component-level repair is possible:

1. History & symptom checklist: we ask what happened, when it started, and whether the set was moved or exposed to moisture.
2. Visual inspection: open the unit (safely, with anti-static precautions) to inspect capacitors, burnt components, connectors, and signs of corrosion.
3. Power rail checks: measure voltages to confirm regulators and supply rails are stable.
4. Boot tracing: trace boot sequences using LEDs and test points to determine where boot fails.
5. Software checks: attempt to reload or reflash firmware if corruption is suspected (only when supported by the manufacturer or with tested recovery images).
6. Component-level testing: where possible, test and replace failed capacitors, diodes, or regulators to see if the set returns to normal.
7. Cross-testing with known-good boards: If available, we may test the panel and power section with a working main board to isolate the failure.

We document the findings and provide a clear recommendation: component repair if durable and cost-effective, or motherboard replacement if repair is risky or parts aren’t available.

Repair vs. replacement: choosing the best route

Component-level repair (replacing capacitors, regulators, damaged ICs):

• Pros: cheaper when the issue is limited (e.g., bulging capacitors), maintains original firmware and OEM configuration.
• Cons: sometimes a short-term fix if there is widespread PCB damage or multiple failing components; requires high skill.

Motherboard replacement (swap the entire main board):

• Pros: faster, more reliable for complex or multiple-fault failures, restores factory firmware and features, and often comes with a parts warranty.
• Cons: usually higher cost than a single-component fix and requires sourcing the correct board for model and firmware version.

Refitec advises honestly — where component repair offers reliable long-term operation we prefer that; where replacement is safer or cheaper in the long run we recommend a motherboard swap.

Sourcing spare motherboards and parts in Nairobi (availability)

Refitec maintains an extensive stock of spare parts for popular brands (Samsung, LG, Sony, Hisense, TCL, Panasonic, Philips and more). We also source parts through trusted suppliers to ensure authenticity and compatibility. For older or rarer models we can sometimes rework or repair the existing motherboard when identical replacements are unavailable.

Key points on availability:

• Popular contemporary models: high availability of mainboards and firmware-matched boards.
• Older sets (5+ years): supply depends on model popularity — sometimes we recommend component-level repair.
• Branded vs aftermarket boards: Refitec prefers OEM or high-quality equivalent boards and will inform you when an aftermarket board is proposed.

All spares are tested before fitting and carry a warranty term which will be communicated on the job sheet.

The replacement process (step-by-step)

1. Booking & inspection: call Refitec (0704843613) to book a diagnostic. We can either collect the TV or conduct a home visit in Lavington.
2. Detailed diagnosis & quote: we diagnose and provide a written estimate — parts, labour, and warranty.
3. Approval & parts ordering: after you approve, we source the correct mainboard (match by model, chassis, and firmware version).
4. Fitment & testing: the board is fitted, connectors rechecked, firmware updated if necessary and the set undergoes a full burn-in (several hours of testing) to confirm stability.
5. Customer handover & warranty: we explain the work performed, return any replaced parts where appropriate, and provide a warranty card for the replaced board.

Turnaround times vary by parts availability, but we aim to complete most local jobs within a reasonable timeframe and keep customers updated throughout.

Pricing factors (what affects the cost)

• Brand & model: premium brands and large models tend to have costlier boards.
• Board availability: in-stock parts cost less than special orders.
• Labour complexity: some boards require panel removal or complex reassembly.
• Repair vs replacement: component repair is usually cheaper, full board swap is costlier.
• Warranty coverage: boards with extended warranties may cost more but offer long-term protection.

Refitec provides transparent quotes — no hidden fees.

FAQs

Q: Will I lose my smart TV apps and settings when you replace the motherboard?
A: If a motherboard replacement is performed with a matching OEM board (same firmware family), apps and settings often transfer or can be reinstalled quickly. If the firmware differs, some settings may need reconfiguration — we’ll advise beforehand.

Q: Is it safe to travel with a TV that has a suspected motherboard fault?
A: Transport can worsen loose solder joints or cracked components. If the set is suspected of motherboard issues, it’s best to secure the TV and inform the technician; in-home diagnostics are safer.

Q: Do you offer on-site repairs in Lavington?
A: Yes — Refitec offers in-home diagnostics and repairs for Lavington residents when the job can safely be completed on-site.
