Black Square Covers 80% of screen on most channels on TV

I have a 35" CF35E50 Toshiba. Have Comcast cable. I get a good full picture on about 8 channels and all the others (70 or so) I have a large black square covering the picture except for the outer 2 inches of the screen. The cable channel number will show in the bottom right corner of the black square. Sound is good on all channels. The other 2 TV's in the house have no problem, so it's not the signal. No channels are locked and a cable box is not used.

White/Grey screen with non-HD channels

I removed the HDMI cable and connected with component video and rca audio. No more white screen.

Picture quality looks good. I don't know if it's as good as HDMI, but then I don't need to reboot the TV three times to get to teh on-demand menu... Grrrrr....

I am trying to contact Toshiba on this as well. I have seen several reports of this problem on the web.
