why does my plasma tv screen occasionally blank

I have a Samsung PN42A450 connected via hdmi to pioneer elite vsx 92 txh receiver. my time warner hd cable box is also connected to the receiver via hdmi.
My problem is every few weeks on some occasions the tv screen goes completly blank and black for a second or two without any sound and then comes back to normal. this keeps repeating sometimes every few minutes.Please advice
thank you.

I'm suspecting the cablebox because I'm getting dropouts while watching recorded programs via the DVR.

I'm going to try component cable next. i just hope its not the plasma.

try adding even an indoor antenna temporarily to see if it is... or hook the DVD player up to the plasma directly.

if the only source which allows the intermittent reception is the cable box, then it's not the new TV. regardless the cables being used.

Trying other sources first, AND THEN other CABLES going into the TV sure ought to isolate where the issue stems from BETTER.

Very good luck.

i decided not to call the cable company because after a day the problem just vanished..and i did not manipulate anything to solve the problem.

FYI, I was having the same problem with a lcd tv I recently purchased for a bedroom. I swapped out a cheapo Hdmi cable with one of better quality and it solved the problem. I think the connectors on the cheap cable were the problem, i.e. they did not seem to be snug in the socket.
