Samsung tv turns on and off. No picture at all. Tried quick fixes can’t do too much when their is no picture. Is this tv junk now??
@boscoevich there are many of reasons why this can happen. Does the POWER LED showing any light? Very first thing you want to do is to unplug the TV. Then unplug EVERYTHING that is plugged in the TV itself. Every input source, sound board, Firestick, SAT box, Cable box etc. or whatever else is connected to it. Then push and hold the power button down for about a minute or so. After that, connect one input source,(preferably a local source like a DVD or BR player, game console etc.) and the plug your TV in. See if it comes on and stay on. If it does not, then it is time to take a look at the boards. Unplug your TV and remove the back cover. Do not touch anything on your boards with your fingers since your TV’s capacitors can still carry a charge and may zap you. Take a good look at those boards. Visually check for anything that looks odd, missing, charred, or otherwise damaged. Take some good pictures of all of the boards and post those pictures with your QUESTION. That way we can see what you see. Your TV may turn off because of missing “feedback” from the other boards. You will need a multimeter to measure the outputs from the power boards to the main board and signals from the main to the power board. If you post some pictures, we can hopefully guide you better with that. Is this tv junk now?? Not until it is all checked! For as long as it is not the panel (unlikely), the majority of times a board change will fix it
