It also lists the major roads, estates and residential areas in Nairobi that we service. This is a practical, SEO-friendly resource for homeowners, landlords, lodges, and small businesses looking for reliable LG TV motherboard replacement and repair.

Why the motherboard matters (and why people call it the “brain” of the TV)

The motherboard (also called the main board, logic board, or main PCB) is the electronic hub of your LG TV. It handles:

• Power distribution to other boards (with help from the power board).
• Video processing and signal routing (HDMI, USB, tuner).
• Smart TV functions: apps, Wi-Fi, Ethernet, software/firmware.
• Audio controls and input/output switching.
• Communication between other boards (T-con, power, backlight drivers).

When a motherboard fails, symptoms vary widely — from no power at all, to sound without picture, to no smart features, to odd on-screen artifacts and random reboots. Because the motherboard interfaces with almost every subsystem, replacing it often resolves a broad class of issues that are otherwise time-consuming to diagnose.

Common symptoms that point to motherboard failure

Here’s a checklist of symptoms that commonly mean the LG TV main board is faulty (or VERY likely to be):

1. TV doesn’t turn on at all — press power, no LED, no sound, black screen (confirm power board and power supply first).
2. TV has power LED but no picture — standby/LED on but blank screen; sound may be present.
3. Image is distorted — horizontal/vertical lines, artifacts, corrupted colors that appear regardless of source (HDMI, tuner, USB).
4. Frequent random reboots or boot loops — TV restarts by itself or shows LG logo repeatedly.
5. No HDMI inputs recognized — “no signal” across sources, or HDMI devices not detected.
6. Smart TV functions fail — Wi-Fi won’t connect, apps crash, firmware updates fail.
7. No audio from speakers but menu sound present — sometimes audio IC on motherboard damaged.
8. IR remote not working / front buttons unresponsive — remote receiver or main MCU issue.
9. Burnt electronics smell, visible damage or bulging capacitors on the main board.
10. TV was struck by a power surge — symptoms may show days later as intermittent faults.

Before deciding on a replacement, skilled diagnostics are essential — sometimes the root cause is a failed capacitor, a shorted component, or a faulty connector rather than the entire board.

Diagnostic steps Refitec follows (what we do when you bring an LG TV)

Refitec’s technicians follow a structured diagnostic roadmap to confirm the motherboard is at fault:

1. History & symptom interview — when did the problem start, was there a surge, any physical damage, does it happen across sources?
2. Visual inspection — look for bulging/leaking capacitors, burn marks, cold solder joints, corroded connectors, or liquid damage.
3. Power checks — test standby voltage rails, power board outputs, and confirm correct voltages reach the main board.
4. Signal route verification — test T-con, LVDS/eDP cables, screen backlight and panel functionality to rule out display panel/T-con issues.
5. Peripheral tests — verify HDMI/USB devices on another TV; test Wi-Fi module connectivity.
6. Firmware & software checks — try safe boot, firmware recovery, or factory reset (if accessible).
7. Motherboard swap or bench test — when safe, swap with a known-good board (or test suspected board on bench) to confirm failure.
8. Detailed component tests — check for short circuits on power rails, measure key ICs if necessary.

Only after these checks will Refitec recommend a replacement. If the motherboard is economically repairable (e.g., a few damaged components), we offer repair as an alternative to replacement.

Replacement vs repair: which is right?

• Repair (component-level)
  • Pros: cheaper, keeps original parts, can be fast if parts available.
  • Cons: not always possible (severe IC failure or BGA IC faults), may not be reliable long-term after repeated failures.
• Replacement (swap main board for a good one)
  • Pros: more reliable, returns TV to original functionality, faster when donor/new board is available.
  • Cons: cost can be higher than small-component repair; requires matching board firmware/part number.

Refitec evaluates the long-term cost and the user’s preference. For older sets where the main board cost approaches new TV price, we’ll advise accordingly.

How we source LG motherboards and spare parts

Refitec maintains a network for sourcing LG main boards and compatible spares: official OEM parts when available, high-quality refurbished boards, and quality-tested aftermarket options. We stock common boards for popular LG series (e.g., 4K smart LED/LCD, OLED models, midrange 32–55″ mainstream sets).

When an exact OEM board for your model is unavailable, we look for compatible boards with the correct part number, firmware version range, and connector layout. Our technicians confirm compatibility in-house before fitting.

Important notes:

• Matching board part number and firmware revision is critical for display and smart feature compatibility.
• Serial/data stickers, connectors (LVDS/eDP), and IR/Wi-Fi module placements must match.
• For OLED panels and modern LG sets, software/firmware pairing is sometimes required.

The replacement process — step by step (what to expect at Refitec)

1. Initial assessment & quotation
   • We diagnose, confirm main board fault, and give a written quote (parts + labour). No surprises.
2. Order/allocate a compatible board
   • If we have a board in stock, we proceed. If not, we order and notify you.
3. Pre-replacement backup & firmware check
   • We note the current firmware and settings. If required, we download the matching firmware to avoid compatibility issues.
4. Safe disassembly
   • We unplug and remove the back cover, disconnect cables, and carefully remove the old board. We document cable positions and connectors.
5. Visual & cleaning prep
   • Clean connectors and mating surfaces, remove any debris or corrosion, and inspect other boards (power, T-con).
6. Install replacement board
   • Fit the replacement board, ensuring proper seating and connectors. We avoid undue force on delicate ribbon cables.
7. Initial power-on & smoke test
   • Power on with a current-limited supply if necessary; check for smoke, odd sounds, or abnormal heat.
8. Functional testing
   • Verify picture, sound, HDMI inputs, USB, Wi-Fi/Ethernet, apps, remote control, and other features. We cycle through multiple inputs and run stress checks.
9. Firmware updates & calibration
   • Flash or update firmware if needed, and run display calibration if requested (basic color/tint/brightness adjustments).
10. Final checks & warranty
    • We test for 24–72 hours (where feasible) to ensure stability. Refitec provides a workmanship warranty on the replacement and installation.

What you’ll pay (cost considerations)

Costs vary widely depending on model, board availability, and whether we use OEM, refurbished, or aftermarket parts. Price factors:

• TV model and series — high-end OLED/mainstream smart TVs often have more expensive boards.
• OEM vs refurbished — OEM new boards cost more; refurbished are cheaper but tested.
• Labour — complexity of disassembly, size of TV, and troubleshooting time.
• Firmware pairing or special calibration — may add time/cost.
• Additional parts — if we find failed capacitors, connectors, or auxiliary boards that must be replaced.

Refitec provides transparent, itemized quotes before any work begins.

Warranty and post-repair support

Refitec stands behind our work. Typical warranty terms:

• Workmanship warranty — covers installation faults for a specified period (e.g., 30–90 days).
• Part warranty — depending on part source: OEM boards usually carry longer warranties; refurbished parts come with a shorter warranty window.

If the same fault reappears within the warranty period and it’s related to the replaced board, we repair or replace at no extra labour cost (subject to warranty terms). We also offer paid maintenance and preventive checks.

Safety & data considerations

• Power safety: Boards are tested using proper ESD protection and current-limited power supplies where needed. Don’t open the TV yourself unless you are trained — there are lethal voltages present in some power sections.
• Smart TV accounts: If your LG TV uses personalized accounts or app logins, consider signing out before handing over the TV (we can help clear any account or reset safely).
• Data privacy: Refitec will not access personal account credentials. If we need to factory reset the TV, we’ll tell you in advance.

Preventive measures to extend motherboard life

1. Use a good surge protector or UPS — power surges are a leading cause of board damage.
2. Stable ventilation — keep the TV in a ventilated area; heat shortens component life.
3. Avoid moisture — never mount the TV where condensation or splashes can reach vents.
4. Clean dust periodically — dust can trap heat and cause thermal problems.
5. Proper cabling — avoid tugging HDMI or antenna cables; faulty connectors can introduce shorts.
6. Firmware updates — install only official LG updates from trusted sources.

Typical FAQs about LG motherboard replacement

Q: Can Refitec repair my LG TV motherboard instead of replacing it?
A: Often yes — if the fault is component-level (leaky capacitors, blown diodes, bad solder joints). We recommend repair when it’s cost-effective and reliable; otherwise, we advise replacement.

Q: Do you need the original remote or can you use a universal remote?
A: Original remote makes testing easier (some LG functions require factory remotes), but we can use a universal remote or the TV buttons for many checks.

Q: Will firmware be lost after board replacement?
A: If the new board has a different firmware version, we may update/flash it to match the TV panel. Refitec will document any changes.

Q: What if my TV is under manufacturer warranty?
A: If it’s under valid LG warranty, we advise contacting LG support first — opening the TV or using third-party parts may void the warranty. We can coordinate authorized repairs if needed.

Q: Do you offer on-site board replacement (home visit)?
A: For larger TVs or customers who prefer not to move the TV, we provide on-site replacement in many Nairobi areas. Extra callout fees may apply.

Aftercare — what to monitor after replacement

• Watch for stability: ensure no reboots, no HDMI dropouts, apps run normally.
• Check for heat: normal warmth is expected, but not excessive hot spots.
• Observe for intermittent issues: sometimes intermittent problems surface later; contact us if issues reappear within the warranty period.
