Does the problem also happen when you play a DVD or HD-DVD on the Sharp? If so, then it's likely the TV. If not it might or might not be the TV.

You can try moving the cable boxes around between the TVs and see if the problem follows the receiver.

If the receiver is also a DVR, anytime you see the flash, stop, "rewind" and look for it again at that spot. If you see it, it's not the TV, it's either the provider signal and it was recorded to the disk or the DVR hard disk is becoming corrupted.
