Prologic-Technologies: Nairobi’s trusted TV IC specialists.
Display Driver ICs control pixel firing across TV panels. When they fail, screens go black, show lines, or lose colors. Heat, voltage spikes, and manufacturing defects kill these chips. Prologic-Technologies at Luthuli Avenue uses hot air stations to desolder and replace them flawlessly. Nairobi’s power surges accelerate IC burnout, making this service essential.
Technicians identify bad ICs via thermal scans—overheating chips glow under IR cameras. Multimeters test data lines for shorts. Failed drivers block LVDS signals from T-Con boards, starving panels of image data.
Common Failure Symptoms
Vertical colored lines signal COF driver failure. Half-screen blackouts point to row drivers. Flickering gradients reveal timing faults. Dead sections after lightning hits scream IC damage.
Static discharge from users zaps ESD-sensitive chips.
Diagnostic Precision
JTAG probes read chip IDs. Logic analyzers capture LVDS streams. X-ray inspection reveals solder voids pre-repair.
Prologic maps panel pinouts for exact replacements.
Replacement Process
IR preheating prevents board warpage. Nitrogen reflow stations lift old ICs at 220°C. Ultrasonic cleaners prep pads. Stencil printing applies fresh solder paste.
New ICs align under microscopes; VPR stations profile balls. Post-reflow, BIST tests validate.
Flux residues neutralize ultrasonically.
Advanced Techniques
Chip-on-Flex (COF) replacements use laser bonding. Multi-chip modules reball entirely. Firmware flashes sync new drivers.
Underfill epoxies secure against vibration.
Benefits Delivered
Restores full resolution instantly. Costs 60-80% less than panel swaps. Extends TV life 4+ years.
Prevents cascading failures to panels.
