Turn it on and it turns right off

My tv turns on then turns right back. The picture is not good. I have to turn it on and off four or five times before it stays on. Don't know what the deal is

ANSWERS:

Hopefully this is helpfull. unplug tv cord from socket or outlit, hold power button for 1 minute, release, then wait 10 minutes, after that, plug back in the cord to outlet, then try it.
