Polaroid LCD TV image problem. Somehow this wound up listed here under projection tv

Question

Somehow this wound up listed here under projection tv troubleshooting. Actually, it is a widescreen LCD. Occasionally some portion of the screen on my Polaroid TDA-03211C TV/DVDcombo will momentarily display a low-resolution (large pixels)freezeframe. This may happen 3 or 4 times in the space of 2 minutes, or maynot happen at all for a couple of hours.
