Sound no picture

I have a 65 inch flat screen tv rca lcd led. When I turn it on I get a brief picture flash then screen goes black. I still have sound.

Is the TV connected to a cable box? If yes, try switching channels. If the problem still exist, check the possible cables connected to the TV and see if it's plugged in properly.
