Introduction

If your TV turns on but shows no picture, reboots randomly, has no sound, or refuses to load apps, the problem can often be the TV motherboard (also called the main board or logic board). Replacing a TV motherboard is a sensitive repair that requires diagnostics, sourcing an exact or compatible replacement, board-level testing, and careful installation. Refitec — servicing Kilimani and surrounding Nairobi neighbourhoods — provides professional motherboard replacement for LCD, LED, OLED, QLED and older plasma TVs. Call Refitec on 0704843613 or visit refitec.co.ke for booking and enquiries.

This guide explains what a motherboard replacement involves, common symptoms that point to the motherboard, the step-by-step replacement process used by professionals, cost drivers, risks and warranty considerations, tips to preserve your new board, and a compiled list of Lavington estates and roads for readers who may be referencing nearby areas.

What is a TV motherboard and why it fails

The TV motherboard is the central circuit board that coordinates everything: it runs the user interface and apps (in smart TVs), decodes incoming signals, drives the audio/video processor, negotiates HDMI/USB inputs, and hosts the firmware that makes the TV work. Common components on the board include the CPU/system-on-chip (SoC), memory chips, HDMI controllers, power sequencing circuits, voltage regulators, and various I/O connectors.

Motherboards fail for several reasons:

• Power surges and unstable mains can damage chips or voltage regulators.
• Electrolytic capacitor failure (bulging or dried capacitors) — common in older sets.
• Overheating from blocked ventilation or faulty cooling, causing ICs to degrade.
• Firmware corruption — sometimes fixable with re-flash but often needing board replacement.
• Physical damage (liquid spills, drops) that cracks traces or damages components.
• Manufacturing defects or age-related degradation in solder joints (cold/ cracked joints).

Many of these causes are preventable with a good surge protector, proper ventilation, and regular cleaning.

Symptoms that strongly suggest a motherboard issue

If you see one or more of the following, the motherboard is a prime suspect:

• TV powers on (standby LED changes) but no picture.
• Sound plays but screen is black (or vice-versa).
• TV reboots or loops on logo/start screen.
• HDMI inputs not detected, or all inputs fail simultaneously.
• Smart TV apps freeze, crash, or don’t launch while the rest of the TV hardware seems OK.
• TV shows “No Signal” on all inputs while the tuner and cabling are known good.
• Random pixels, distorted menus, or firmware update failures.

A proper technician performs methodical diagnostics to rule out PSU (power supply board), T-con board (for localized panel issues), cables, and panel faults before declaring a motherboard replacement necessary.

How Refitec diagnoses and decides on replacement (professional workflow)

1. Initial remote triage: You’ll be asked a set of symptoms — LED behavior, sounds, whether the unit shows any menu, and the model number. This helps prioritize tests.
2. Physical inspection & safety checks: The technician inspects for physical damage, signs of water ingress, or burnt components. Power is disconnected and the TV opened in a static-safe environment.
3. Measure power rails: Using a multimeter, the tech checks voltages from the PSU to the motherboard. If power rails are absent or incorrect, the PSU might be the problem.
4. Swap/minimal substitution tests: When possible, the tech will swap parts (e.g., a spare PSU) to isolate the failing module.
5. Firmware checks and re-flash attempts: If the TV shows signs of corrupt firmware but hardware seems fine, a firmware re-flash might recover it.
6. Board-level inspection under magnification: Look for bulging capacitors, cracked solder joints, burnt ICs, or torn traces.
7. Decision & estimate: If the motherboard is irreversibly damaged or repair is uneconomical, Refitec will present options: source original replacement board, use a compatible used board, attempt component-level repair (reflow / replace ICs / recaps) or replace with a refurbished OEM board.

Refitec documents all findings and shares an itemized estimate before proceeding.

The replacement process (step-by-step)

1. Model verification & sourcing: The exact model and part number are identified. Refitec will source either a new OEM board, an equivalent compatible board, or a quality refurbished board depending on availability and budget.
2. Power down and component disconnection: TV is unplugged; screws, connectors (LVDS, ribbon cables, HDMI, audio) and the board are carefully removed. Photos are taken to ensure correct reassembly.
3. Static precautions: The tech uses anti-static wrist straps and mats to avoid ESD damage.
4. Install replacement board: Connectors and cables plug in carefully, ensuring no bent pins and correct seating.
5. Initial power test (bench test): With the TV back panel open, the tech powers the TV to verify POST (power-on self-test), menu appearance, HDMI detection and audio.
6. Firmware compatibility check: If the replacement board firmware version differs, the tech ensures compatibility or performs an update.
7. Functional tests: Run through tuners, HDMI inputs, streaming apps (if smart TV), sound, and image quality checks.
8. Final assembly: After full verification, the TV is reassembled and a final burn-in (short stress run) is performed to ensure stability.
9. Customer handover: Refitec explains the repair, warranty terms, preventive tips, and any changes (e.g., if replaced with refurbished board).

Parts sourcing: original vs compatible vs refurbished

• Original OEM board: Best fit — guarantees compatibility and long-term support but is usually the most expensive.
• Compatible aftermarket board: Less expensive but can have quirks (firmware differences, missing features). Suitable when OEM is unavailable.
• Refurbished OEM board: Economical and often reliable if tested. Good middle ground, especially for older models.

Refitec works to source the best option balancing reliability and cost. If an exact OEM board is unavailable, they explain tradeoffs and obtain your approval before using alternatives.

Typical costs and timeframes (estimates)

Costs depend on brand, model, and availability:

• Diagnostics fee: small fixed fee (often deducted from the repair price if you proceed).
• Refurbished motherboard replacement (common models): typically lower cost than OEM — varies widely (ask Refitec for current pricing).
• OEM board replacement (new): highest cost — depends on TV size and brand.
• Labour & testing: included in the quoted price.
• Turnaround time: many commonly stocked boards can be replaced the same day or within 48 hours if in stock; sourcing special parts may take longer.

Because prices and stock vary, call 0704843613 for an exact written quote. Refitec always provides an itemized invoice and warranty on parts and labour.

Risks, when to consider replacing the TV instead

• High cost of motherboard nearing replacement TV price: For older or budget TVs, the cost of a new motherboard (or multiple parts) can approach the price of a good new TV — in such cases replacement may be more sensible.
• Panel damage: If both panel and motherboard have problems, a full replacement is often cheaper.
• Obsolete parts: Very old models may have scarce spares; cost and time to source might be prohibitive.

Refitec will present a cost-benefit analysis so you can make an informed choice.

Warranties and guarantees

Professional workshops typically offer:

• Parts warranty: Usually 30–90 days for used/refurbished parts; longer for new OEM parts depending on supplier.
• Labour warranty: Typically a period during which installation defects are fixed free of charge.

Ask Refitec for written warranty details before authorizing work.

Preventative care to extend motherboard life

• Use a good surge protector or UPS.
• Keep ventilation clear — avoid enclosing the TV in tight cabinets without airflow.
• Dust the TV vents and back panel periodically (power off and unplug first).
• Avoid leaving the TV on for excessively long periods; use screen savers/auto-off where possible.
• Keep firmware up to date using manufacturer updates through the TV menu or USB when provided.

Why choose a professional (like Refitec) over DIY or informal services

• Correct diagnostics: What looks like a motherboard failure can be a PSU, backlight, or panel issue. Professionals identify root causes.
• ESD and safety: Removing and installing boards requires ESD precautions and safe handling of high-voltage capacitors.
• Sourcing & compatibility: Professionals can source tested replacement boards and ensure firmware compatibility.
• Warranty & accountability: Reputable services provide warranty and documented work.

Refitec provides documented diagnostics, tested parts, and post-repair support — contact 0704843613 for details.

Spare parts availability in Nairobi (what to expect)

Nairobi has a robust market for TV spare parts. Many workshops hold stocks of common boards, and there are suppliers that import OEM and aftermarket boards. Refitec maintains relationships with suppliers to quickly source parts for popular brands (Samsung, LG, Sony, Hisense, TCL, etc.). For rare or older models, sourcing may take longer but is often possible.

Pricing transparency & what to ask before authorizing work

Before approving a repair, request:

• Itemised quote (parts + labour + tax).
• Exact part numbers and whether parts are new, refurbished, or compatible.
• Warranty length and scope.
• Expected turnaround time.
• Whether the TV will be tested in-store (recommended) and whether on-site service is available.

Refitec provides clear written estimates and communicates any changes before proceeding.

Frequently asked questions (FAQ)

Q: Can a motherboard always be repaired instead of replaced?
A: Sometimes component-level repairs (replacing capacitors, ICs, reflowing solder) can revive a board. Success depends on the type and extent of damage. Refitec will attempt economical board-level repair when safe and cost-effective; otherwise replacement is recommended.

Q: Will replacing the board affect my TV’s picture quality?
A: With a correct, compatible board and proper firmware, picture quality should be the same. Using incompatible boards or mismatched firmware can cause menu differences or missing features.

Q: Do you transfer my apps/configuration?
A: If the TV stores settings on the board, a board replacement can erase saved Wi-Fi credentials and app logins. Refitec can help reconfigure the TV after replacement but you may need to re-login to streaming apps.

Q: Is data on my smart TV saved anywhere else?
A: Most smart TVs save user profiles and app credentials on the motherboard, so a replacement typically clears them. Take note of user accounts before service if possible.
