samsung hdtv model hcn653wxxaa

i have a samsung and it will make a sound like 'doodle doo doo' and then the timer light begins to flash and the power goes off, then comes back on and does the very same thing.  There is 'sound from a channel' but the screen does nothing.

 

What could be the problem???
