Samsung Model UA40C6900VF started switching on and off repeatedly. Can this be fixed? Have tried switching off an unplugging.
@waverley142 this could be a bad power board (backlight circuitry) or a bad LED array. You will have to remove the back of your set and take a look at all the boards. Look for obviously damaged components like leaking capacitors etc. Post some images of all of your boards with your question. Use this guide Adding images to an existing question for that. It will allow us to see what you see.
