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 had the same problem and found it was indeed the cablebox.
replace it and it should be fine.
Followup:
Well, the dropouts are beginning again even with the new box.
Time to call Cablevision.

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.
