Search VCC-Panel to isolate the electronic switch controlling power delivery to the T-CON board.

The board needs multiple lower voltages to power the processor, RAM, and tuner. The schematic shows small 5-pin or 6-pin buck regulator ICs. 5V, 3.3V, 1.8V, and 1.2V. 5. LVDS Interface Tp.v56.pb801 Schematic Diagram Pdf

The primary side converts 110V/220V AC household power into a stable . A bridge rectifier converts AC to DC, filtered

A bridge rectifier converts AC to DC, filtered by a large 450V electrolytic capacitor. Symptom: Sound Present

If all voltages are correct, the firmware inside the SPI Flash IC is likely corrupted. You will need to desolder the chip and reprogram it with a clean TP.V56.PB801 bin file matching your panel resolution. Symptom: Sound Present, No Picture (Screen is Dark)
