LG TV repair in Nairobi – from LED UQ, NanoCell, QNED, OLED C1, C2, G2. At Best Television Repair Nairobi, we fix LG-specific faults daily.
Common LG Faults
1. Sound but no picture – LG 43UK, 50UP, 55UQ series infamous for backlight failure. LED strips 43LH, 49UJ, 55UK. 2. No power, red light blinking – power board EAX or EAY boards, MOSFET short. 3. Lines, double image – T-Con 6870C, panel tab. 4. Stuck on LG Life's Good logo – mainboard EAX678728, eMMC corruption. 5. Wi-Fi not connecting – Wi-Fi module EAT61783102, common after surge. 6. Magic remote not working – IR receiver or Bluetooth module. 7. HDMI ARC no sound to soundbar – mainboard audio IC.
LG OLED Specifics
OLED C1, C2, G2: pixel refresher stuck, no power after firmware update, mainboard EBT, power EAY. OLED requires ESD-safe handling, no pressure on panel. We have LG OLED jigs.
Our LG Repair Approach
We test backlight with constant current tester, not just voltage. Replace all strips, not one. For NanoCell, we use exact length strips with 3M thermal tape. For mainboard, we reflow or replace eMMC with larger capacity. Firmware via USB: download from LG, extract .epk, put on FAT32 USB, hold power. For webOS, we clear cache partition.
