Measure the voltage across the LED connector pins during power-on. If the voltage spikes briefly up to 90V+ and then drops down to 12V, the board driver is working, but one or more LEDs inside the panel screen are burnt out (open circuit).
This is usually a 6-pin or 12-pin connector connecting the mainboard to the power supply unit.
The board includes an integrated LED driver. If the TV has sound but no picture, check the voltage at the LED output connector (typically marked CN). Firmware Upgrading:
