any RCA TV and DVD player experts?
 

I have a RCA TV and DVD player, and every once in a great while when I push on the remote;

TV > "who.input"

Then

DVD

I get an all grey screen with the words "no signal found"

Never found a reason for this, on/off different DVD's everything then it will work out of the blue.

tonight it happen when we was watching a DVD, after 2 hours the screen went grey and "no signal found" but the DVD was still playing and the sound was still on.

Anyone know any reason why my TV and DVD hate me? Both are 2 years old or so.

It's like if I had satellite TV and a storm came in, but I have cable so I know that's not the issue.

Help!
