Sony televisions rely on advanced motherboards to power smart features, 4K processing, and seamless connectivity. When these boards fail—showing no power, audio issues, or display glitches—downtime disrupts entertainment. Luthuli Avenue in Nairobi stands as the go-to electronics repair strip, packed with skilled technicians. Prologic-Technologies leads here, offering targeted Sony motherboard repairs that revive TVs without full replacements.
Common failures stem from power surges, overheating, or capacitor wear. Symptoms include dead screens, frozen interfaces, or HDMI port failures. Prologic’s team uses oscilloscopes and multimeters to trace issues from T-Con boards to main logic units.
Diagnostic Process
Technicians start with visual inspections for burnt components or swollen capacitors. Power-on tests check voltage rails. Signal generators isolate HDMI or tuner faults.
Firmware analysis via USB tools rules out software glitches. Disassemblies reveal hidden cracks from mishandling. Reports detail findings before approval.
This methodical approach avoids guesswork, saving clients unnecessary expenses.
Repair Techniques
Reflow soldering fixes cold joints on BGA chips. Hot air stations replace faulty ICs like main processors or audio amps. Precision microsoldering handles fine-pitch connectors.
Electrolytic capacitors swap for high-grade equivalents rated for Kenyan voltage fluctuations. Buffer boards rebuild with anti-static protocols.
Prologic stocks parts for models from Bravia series to older LCDs, minimizing delays.
Common Sony Motherboard Issues
Power supply sections fail first in surge-prone areas. Vertical lines signal T-Con problems. No sound points to audio DSP chips.
Smart TV freezes trace to RAM or eMMC storage degradation. Backlight inverters cause dark screens despite power.
Prologic handles all, from entry-level W series to premium OLEDs.
