LG OLED TV no picture no sound but turns on
The TV still can be turned on by the remote or the power button. I can hear the click from the powerboard and the red LED on the mainboard will be on. But no picture no sound. My nintendo switch can turn on the TV via HDMI as it normal dose.
Tried disconnecting speaker, control button and remote receiver one by one noting worked.
Tried disconnected the T con board. The power can be turned on for 2 second and then it will restart it self. And the power stay on for another 2 second before turning off.
Bought a mainboard and put it in, but issues are same.
Tested the power suppy board. The power to the mainboard showed in the pictures. The power to the T con board are all 25.1V for the 24V pins and -1.2mV for the GRD pins.
Is there anything I can do? Many thanks.
Questa è una buona domanda?

@osmanbah1151990 This is an old thread. you should start your own thread and post as much info about your TV (make, model, etc.), what it does, and what you have tried.
