Sony Motherboard Repairs and Replacement

Sony Motherboard Repairs and Replacement

The motherboard, or mainboard, is the central processing hub of every Sony television, controlling everything from image processing and HDMI input handling to smart TV functionality and power regulation. When a Sony television fails to power on, displays no picture despite audible sound, or behaves erratically, a motherboard fault is often the underlying cause. TV Repair Kenya provides expert Sony motherboard diagnosis, repair, and replacement services across Nairobi.

Common Signs of Sony Motherboard Failure

  • Television will not power on at all, despite a functioning power supply and outlet.
  • Standby light on but no picture or sound, suggesting the mainboard is failing to initialize the panel and audio system.
  • Random restarts or shutting down during use, often linked to a failing processor or damaged circuit traces.
  • HDMI inputs not detected, even when connected devices function correctly elsewhere.
  • Distorted or garbled on-screen menus, indicating a graphics processing fault on the mainboard.
  • Burn marks or a burning smell near the mainboard, typically following a power surge — a common risk during Nairobi's occasional electrical fluctuations.

Component-Level Repair vs. Full Replacement

Where possible, our technicians perform component-level repair — replacing individual capacitors, fuses, or ICs on the motherboard — rather than defaulting to a full board replacement. This approach is significantly more affordable and is successful in a large percentage of Sony motherboard faults, particularly those caused by power surge damage rather than physical or liquid damage.
