Once the transformer begins oscillating, an auxiliary winding generates a localized AC voltage, rectified by a fast recovery diode to take over the continuous VCC supply of the PWM IC.

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)

Controls the dimming and brightness level of the LEDs. D. System Controller and Memory

Incorrect LVDS panel voltage or mismatched panel configuration mappings in the firmware.
