I've bought faulty OLED TV. When pressed power button it Powers on for 2-3 seconds. Relay clicks for on and then off click. LG logo fades out.
Checked power supply according to OLED SMPS Testing manual.
All voltages fine. Bulb test fine.
Installed MyRemocon on android device with IR. Pressed "power only" button. Got same cycle like with normal remote.
Inspected LVDS and can 4 cables that goes to panel. Panel cables as new. LVDS contacts slightly discoloured. Cleaned with contact cleaner and brush. No changes.
As member Diah offered disconnected middle two cable going from T-Con to panel. Pressed "power only" this time I've got difference.
TV screen switched on for 1-2 seconds. I could see some green background and a bit of round shape left hand corner, and white horizontal line over top the the screen.
Do I have dead panel and TV does not want to start due to it?
I have attached part and screen photos just in case you need.
