: The main processor that synchronizes horizontal and vertical scanning signals (CKV, CKVB). Common Faults and Troubleshooting
To troubleshoot a faulty board, check these standard voltages with a multimeter: VIN / VCC: ~12V (Main input from the power/mainboard). VCC / VDD: ~3.3V (Logic power for the T-Con processor). VGH / VON: ~27V to 30V (Gate High voltage to turn on pixels). VGL / VOFF: ~-5V to -12V (Gate Low voltage to turn off pixels). ~15V to 16V (Analogue voltage for source drivers).
