Prologic-Technologies: Trusted leaders at Luthuli Avenue for electronics repair.
TCL televisions rely on robust motherboards to process signals, control displays, and manage audio. Faults like no power, dead pixels, or sound failure often trace back to this core component. At Luthuli Avenue, Nairobi’s electronics hub, Prologic-Technologies specializes in TCL motherboard repair. Technicians handle models from 32-inch budget sets to 75-inch QLED units.
Motherboards integrate CPUs, RAM, HDMI controllers, and power circuits. Overheating from dust buildup, power surges, or capacitor failures cause most issues. Prologic starts with visual inspections for burnt traces or swollen components.
Common Motherboard Failures
Power supply sections fail first in Kenya’s unstable grid. Symptoms include intermittent startups or total blackouts. Technicians test fuses, diodes, and MOSFETs with multimeters.
Tuner malfunctions block channels; signal processing chips glitch colors. HDMI ports die from frequent plugging, needing IC replacements. Backlight inverters overload, dimming screens unevenly.
Software corruption mimics hardware faults—firmware flashes resolve these. Prologic uses JTAG programmers for deep resets.
Diagnostic Process
Customers bring TVs to the Luthuli Avenue shop. Staff log details: model number, symptoms, usage history. Units connect to test benches with dummy loads.
Oscilloscopes trace voltage ripples. Thermal cameras spot hot zones. Component-level probing isolates failures—90% accuracy on first pass.
Free diagnostics take 30 minutes; quotes follow immediately.
Repair Techniques
Board extraction requires panel disassembly. Anti-static mats prevent ESD damage. Faulty SMD capacitors desolder precisely; ceramics or tantalums replace them.
Trace repairs use jumper wires. IC chips reprogram or swap—Prologic stocks TCL-specific mainboards. Reflow soldering fixes cold joints from vibrations.
Firmware updates via USB restore smart features. Full board swaps suit severe damage, sourced from verified suppliers.
Cleanups involve compressed air and IPA wipes, preventing recurrence.
