Screen flashes the LG Logo for a few seconds and then goes black
Turned on my LG32 LEDTV & it flashes the LG Logo for a few seconds and then the screen goes black. The sound is on.
@dbgarasiya let us know the exact model for your TV. Once the screen is black and you can hear audio shine a Flashlight at an angle against the screen. See if you can make out shapes, silhouettes. LG has issues with the backlight. If it does not then you want to consider removing the back from your TV and check the power board and the main board. You’ll need a multimeter to do so. Pictures of your boards will help us to see what you see . Post some with your question Adding images to an existing question
