Introduction

Sony Bravia TVs are synonymous with crisp picture quality, excellent color rendering, and reliable performance. However, like any complex electronic device, they can experience faults — and one of the most serious is a motherboard (main board) failure. The motherboard is the TV’s central nervous system: it handles power management, video processing, input/output control, firmware, and communication with the display panel and power supply. When it fails, symptoms can vary from no power to audio-only, distorted picture, or recurring boot loops.

At Refitec, we specialise in diagnosing, repairing, and where necessary replacing Sony Bravia motherboards for owners across Nairobi and the wider Kenyan market. This document explains in practical detail how we diagnose faults, our step-by-step replacement process, parts sourcing and warranties, what to expect in terms of cost and turnaround, and how customers can avoid future issues. If you own a Sony Bravia TV and suspect a motherboard problem, this guide will help you understand the process and why Refitec is a trusted choice.

How to tell if the motherboard is at fault — common symptoms

Not every TV problem is a motherboard issue. But these signs commonly point to mainboard failure:

1. No power / dead TV — no LEDs, no response when pressing power. (Confirm power outlet and power board first.)
2. Power LED on but no picture — sound may work but screen stays black or the backlight turns on briefly and off.
3. Boot loops / reboots — TV powers on then shuts down or reboots repeatedly.
4. No signal from HDMI / inputs — inputs show ‘no signal’ even with a working source.
5. Strange artifacts / corrupted picture — lines, blocks, or scrambled video despite a good panel.
6. Remote control commands ignored, or features like Wi‑Fi / Smart hub not functioning.
7. Burnt smell or visible damage around the mainboard area — once observed, power down the set and seek professional help.

Many of these symptoms can overlap with power supply board or T-Con (timing controller) problems. A careful diagnostic flow helps identify the true faulty module.

Our diagnostic process (what we do, step-by-step)

1. Initial customer history & remote troubleshooting: We start with a detailed history — model of TV, serial number, when the fault began, recent incidents (power surges, lightning, physical shock), and any prior repairs. We also guide simple tests the customer can run (different outlet, different HDMI cable) to rule out user-level issues.
2. On-site checks (if requested): For customers who prefer not to move the TV, we send a technician for an on-site inspection. The tech will verify power integrity, LED/panel behavior, and basic signal tests.
3. Workshop diagnostics (recommended for motherboard faults): For full diagnostics we bring the TV to our workshop or accept collection/courier delivery. In the workshop:
   • We perform a power rail check to ensure the power supply board outputs correct voltages to the mainboard. Many ‘dead TV’ issues are power-related rather than mainboard failures.
   • We use a serial debug procedure where applicable — watching boot logs (if available) to locate firmware or processor hang points.
   • We test peripheral interfaces — HDMI, USB, Wi‑Fi module, Ethernet — to isolate the failing domain.
   • We inspect the board under a microscope for blown capacitors, cracked solder joints, cold solder joints, and burn marks.
   • If the TV boots partially, we run software/firmware verification to confirm the OS and firmware checksums.
4. Report & quotation: After diagnostics (normally within a few hours to 48 hours depending on backlog and complexity), we provide a clear report: what’s faulty, whether a repair (component-level rework) is possible, or whether replacement of the mainboard is the recommended option. We include a transparent quotation for parts, labour, and estimated lead time.

Repair vs replacement — when we replace the motherboard

Not all mainboard faults require full replacement. Our approach is conservative and value-driven:

• Component-level repair: When the fault is due to discrete components (damaged capacitors, MOSFETs, power regulators, burnt resistors, failed eMMC chips that can be reprogrammed), we favour repairing the board. Component-level repairs are cheaper and preserve the original firmware and serial-linked credentials.
• Rework & reballing: In some cases, CPU or memory BGA chips require reflow or reballing. We only undertake such micro-soldering when the prognosis is good and the cost is justified compared to replacement.
• Replacement: We recommend full mainboard replacement when the board has catastrophic damage (severe burn, multiple failed ICs), when required components are unobtainable, or when the client prefers a guaranteed factory-equivalent assembly. Replacement is also faster when a compatible and reliable spare is available.

Sourcing parts — genuine vs high-quality equivalents

Parts sourcing is crucial. Refitec aims to use genuine Sony replacement boards where available, or high-quality equivalent boards from reputable suppliers when genuine boards are unavailable or excessively costly.

• Genuine Sony mainboards: These are ideal because they carry the original firmware and compatibility assurance. However, genuine boards for older models can be scarce and expensive.
• Tested aftermarket boards / refurbished boards: We source these from known suppliers, test them thoroughly in our workshop, and reflash firmware where necessary to match the TV’s region and model.
• New aftermarket boards: Many third-party boards are technically compatible, but we only use those that pass our compatibility and quality checks.

We always disclose what type of board we will use and the associated warranty.

The replacement procedure (workshop standard)

1. Pre-replacement backup & checks: If the TV stores user settings or calibration, we back up where possible (some Sony smart TVs tie user profiles to specific hardware — we document this and advise customers of potential data loss).
2. Safe disassembly: We discharge capacitors and follow ESD-safe procedures. Front panel, back cover, and internal modules are removed carefully to avoid damage to the display panel.
3. Labeling & photography: Each connector and screw is labelled and photographed to ensure correct reassembly.
4. Removal of faulty board: The faulty motherboard is unplugged from harnesses, HDMI, LVDS/eDP connectors, speakers, and power connectors. If there are fixed heatsinks or shields, these are removed as per Sony service manuals.
5. Pre-test replacement board: The replacement board is tested outside the chassis where possible to verify basic power-up and boot behavior before permanent installation.
6. Installation & final testing: After installation, we run a full test suite:
   • Boot test for prolonged periods to ensure stability.
   • HDMI and input tests across multiple ports.
   • Audio and video quality checks, including color calibration checks where relevant.
   • Smart TV functions and network connectivity tests.
7. Firmware update & calibration: We match or update firmware for regional compatibility and load any necessary calibration files.
8. Clean up & delivery: The TV is reassembled, surfaces cleaned, and returned to the customer with a test report and warranty card.

Typical turnaround time and logistics

• Diagnostics: same day to 48 hours (workshop) depending on complexity.
• Repair (component-level): 1–5 working days on average.
• Replacement with in-stock board: 1–3 working days.
• Replacement with ordered board: 7–21 days depending on part availability and shipping.

For customers outside Nairobi, we accept couriered units and ship back repaired TVs or ship boards and provide remote guidance for trusted technicians to install locally.

Costs and pricing guidance (estimates)

Costs vary by model and the chosen repair path. Below are ballpark figures to help customers plan (all figures in Kenyan Shillings, KES):

• Diagnostic fee: small fixed fee (often waived or rolled into repair cost if you proceed).
• Component-level repairs: KES 3,000–15,000 depending on parts and labour.
• Mainboard replacement (aftermarket/refurbished): KES 8,000–35,000 depending on model year and board availability.
• Genuine Sony mainboard replacement: often KES 20,000–70,000 or higher for premium/large models.
• BGA rework or eMMC reprogramming: KES 7,000–25,000 depending on the complexity.

These are estimates. Refitec provides a written quotation after diagnostics. We prioritise transparency — no hidden fees.

Warranty, quality assurance & post-repair support

Refitec stands behind our work. Warranties depend on parts used:

• Genuine boards: warranty typically 6–12 months (parts & labour negotiable per case).
• Refurbished/tested boards: warranty typically 90 days to 6 months depending on source and condition.
• Component-level repairs: warranty typically 90 days to 12 months depending on the work performed.

All repaired units undergo a burn-in test and our technicians provide a test report and care tips. If the issue reoccurs within the warranty, we prioritise corrective action.

Safety advice for customers

• Power down and unplug a TV immediately if you smell burning or see smoke. Do not attempt to continue using it.
• Avoid DIY motherboard replacement if you lack ESD-safe tools and soldering experience. Motherboard work often requires microsoldering, firmware flashing, and BGA rework.
• Keep firmware updated where Sony provides updates, but coordinate with a technician for firmware changes when a board swap occurs because region and model-specific firmware differences can cause issues.
• Use surge protectors and, where feasible, uninterruptible power supplies (UPS) to protect TVs from brownouts and spikes.

Common Sony Bravia models & specific notes

Different Sony Bravia series (e.g., KDL, KD, XBR, OLED/A8/HDR models) have different common faults and board architectures. For instance:

• Older LCD/LED models: common issues include blown capacitors, failed power regulators, and aging eMMC memory.
• Smart TV models: more likely to face firmware corruption, Wi‑Fi module failure, or software-level boot loops.
• OLED / high-end models: boards are sometimes unique and more costly; sourcing genuine boards is recommended.

Frequently asked questions (FAQ)

Q: My TV has sound but no picture. Is it the motherboard?
A: Possibly. It may be the T-Con board, backlight inverter (on older CCFL TVs), or mainboard video output section. We run tests to isolate the exact module.

Q: Can you program my TV’s serial or MAC address after a board swap?
A: Some boards require reprogramming/EEPROM adjustments to match the original set. We handle this where legally and technically feasible; some changes may affect warranty or platform features.

Q: Will replacing the motherboard erase my apps and settings?
A: Often yes. Some Smart TV profiles are tied to internal storage. We advise backing up credentials and informing the technician of important settings.

Q: Is it worth repairing an old Sony Bravia?
A: It depends on model age, repair cost, and availability of spare parts. We provide a cost-benefit analysis after diagnostics.

Maintenance tips to avoid mainboard failure

1. Keep vents clear — overheating shortens component life.
2. Use surge protection — protect against grid spikes and lightning.
3. Avoid long continuous runtimes at max brightness — this stresses power circuitry over time.
4. Annual dust cleaning — dust buildup can cause overheating and shorts.
5. Install updates when stable — avoid installing beta or unofficial firmware builds.

Real case examples (anonymised)

1. Case A — Boot loop on 2016 Sony 43-inch: Symptoms were repeated reboots. Diagnostics traced the issue to corrupted eMMC storage on the mainboard. We performed BGA-level rework and eMMC reprogramming; TV returned with data intact and stable operation.
2. Case B — No power on 2014 model: Visible bulging capacitors on the mainboard. Component-level repair with high-quality capacitors restored function at a fraction of the cost of a full replacement.
3. Case C — Smart functions dead after power surge: Mainboard had multiple burnt ICs. We sourced a tested refurbished board, matched firmware, and returned the TV fully functional. Customer opted for genuine-board warranty upgrade later.
