Cost-Effective Fixes: 60-80% savings vs. new panel replacement.
The Display Interface Board (DIB), often called the T-Con or Timing Controller board, serves as the brain connecting panels to mainboards. When it fails, TVs show lines, ghosting, or no image despite power. Prologic-Technologies at Luthuli Avenue repairs these daily, handling Nairobi’s power surge-damaged units. Loose LVDS cables cause 40% of issues; burnt ICs from overheating claim the rest.
Technicians use JTAG debuggers to read error logs. Thermal scans reveal hot chips. Signal generators test input-output paths end-to-end.
Common Failure Symptoms
Vertical colored lines streak screens from timing sync loss. Flickering or half-images signal LVDS corruption. No display with sound points to scaler failure. Ghosting trails fast motion due to frame buffer overflow.
Nairobi’s unstable voltage fries voltage regulators on boards. Dust buildup shorts pins in humid seasons.
Diagnostic Workflow
Power-off disassembly uses anti-static tools. Multimeters probe rail voltages—3.3V, 5V, 12V rails must hold steady. Oscilloscope waveforms verify clock signals at 100-200MHz.
EEPROM dumps reveal firmware corruption. Burn-in tests stress boards for latent defects.
Repair Techniques
IC reflow stations revive desoldered chips under nitrogen flux. Firmware reflashing via USB restores factory timings. LVDS cable swaps use gold-plated replacements for impedance matching.
Failed scalers get socketed bypass mods. Voltage stabilizers add surge protection inline.
Prologic stocks boards for 55-85 inch models, common in Kenyan homes and bars.
Advanced Solutions
Custom LVDS extenders fix long-cable signal drop. Gamma correction LUTs upload for color accuracy. Panel lot matching ensures compatibility—mismatched boards cause artifacts.
BGA rework stations handle 400-pin controllers precisely.

Post-Repair Care
Secure cables with zip ties to prevent flexing. Install UPS units for clean power—AVR alone insufficient. Clean board vents yearly with compressed air. Avoid stacking devices that block airflow.
Firmware updates patch timing bugs—Prologic provides USB files post-repair.
Annual board health checks at KES 1,500 prevent failures.
Nairobi-Specific Advantages
Prologic sources parts from Asia weekly, beating import delays. Trained on latest mini-LED and QLED boards. Handles smart TV overlays without data loss. English/Swahili service builds trust.
Walk-ins test repaired TVs live before payment.
