Motherboard Replacement for Sony TVs: Fast Nairobi Repair Service

Motherboard Replacement for Sony TVs: Fast Nairobi Repair Service

The motherboard is the largest and most important circuit board inside any Sony television, and when it fails, the entire set appears dead or deranged. If you are searching for a dependable Sony TV motherboard replacement in Nairobi, Pro-Logic Technologies on Luthuli Avenue offers fast diagnostics, genuine and compatible replacement boards, and component-level repairs that often save the original board entirely.

Understanding the Sony TV Motherboard

In television repair terminology, the motherboard is the central board on which the main processor, memory, tuner, input ports, and control circuits are mounted. In Sony service literature it is often called the A-board or the main board, but technicians and customers alike refer to it as the motherboard because every other subsystem connects to it. The motherboard receives power from the power supply, takes in signals from HDMI, USB, and broadcast tuners, processes them into video and audio streams, and sends the finished picture data to the T-con board for display on the panel. It also runs the Android TV or Google TV operating system found on modern Sony BRAVIA models. A fault anywhere on this board can therefore present as an almost unlimited variety of symptoms.

Common Sony Motherboard Failure Symptoms

1. Television will not boot or is stuck on the Sony logo. Boot memory or processor faults prevent the operating system from starting.
2. Black screen with sound, or no picture and no sound. The board stops processing or outputting signal entirely.
3. HDMI ports dead or intermittent. Damaged HDMI receiver chips or physically worn ports are common after power surges.
4. No Wi-Fi, no Bluetooth, or missing apps. Wireless modules and smart functions are managed by the motherboard.
5. Remote and buttons unresponsive. The infrared receiver and control circuitry have failed.
6. Random freezing, rebooting, or shutdowns. Degraded components and cracked solder joints cause intermittent faults.

Our Motherboard Repair and Replacement Process

At Pro-Logic Technologies, Kangari Building, we never replace a board on guesswork. Every television first undergoes a full diagnostic that tests the power supply, motherboard, T-con board, and panel to confirm the exact cause of the fault. You then receive a written quotation with a plain-language explanation. Our first preference is always component-level motherboard repair: our technicians replace failed regulators, eMMC memory chips, HDMI receiver ICs, and damaged ports using precision soldering equipment, preserving your original firmware and settings. Where the board is beyond repair, we supply a matched genuine or compatible Sony motherboard, transfer and configure the firmware where required, and fully test the television before it leaves our workshop. Most repairs are completed within one working day, and every job carries our service warranty.

FAQs

1. How much does a Sony TV motherboard replacement cost in Nairobi?
Costs vary by model and screen size because motherboards differ widely across the BRAVIA range. Component-level repairs are usually the most economical route. We give a written quotation after diagnosis, with the diagnostic fee waived when you proceed.

2. How long does a Sony motherboard replacement take?
Most component repairs are completed within one working day. Full replacements are usually same-day or next-day when the board is in stock; special-order boards for rarer models may take two to three days.

3. How do I know if my Sony TV motherboard is faulty?
Common signs include boot loops, logo freezes, black screens with sound, dead HDMI ports, missing smart functions, and ignored remote commands. However, these symptoms overlap with power supply and T-con faults, so professional diagnosis is essential.

4. Can a motherboard be repaired instead of replaced?
In most cases, yes. Our technicians routinely replace individual failed components such as regulators, memory chips, and HDMI ports, which is cheaper than a full board replacement and preserves your firmware and settings.

5. Do you offer a warranty on Sony TV motherboard repairs?
Yes. Every motherboard repair and replacement at Pro-Logic Technologies is covered by a service warranty on both workmanship and installed parts. Bring your television to Kangari Building, Luthuli Avenue, or call 0723 763 173.
