Why is my tv turning off and on again with weird noises?

My tv continuously flicker(sometimes it goes black and white) for a couple seconds and then turns itself off and on again while screeching weird noises out and i don’t know what to do. Been happening for a while but getting a lot more common now that it is unbearable, like every 5-10 minutes

Maybe something has gone wrong with the power? Sorry, I don't know too much about TVs. Every once in a while your tv turns on and off while making a high-pitched screeching noise?

@campbellgarner all of this "sometimes it goes black and white) for a couple seconds and then turns itself off and on again while screeching" sound like a main board issue. Possibly the video input circuitry. Let us know what exact model your TV is. Try different video input sources and see if that makes a difference. If it does not you do want to go ahead and remove the back cover and check the main board. Post some good pictures of your boards so we can see what you see Adding images to an existing question - iFixit Repair Guide
