Question about Samsung PCH521R 52" Rear Projection Television
I have a 30" samsung tantus HDTV that is pinching the image horizontally on the right and left sides. It started out somewhat gradually - i.e. turn the TV on, see the pinched image, then turn it off then on again and the image would be fine. Sometimes it wouldn't do it at all. Now, though, it seems to be permanent. It does it not matter what the input - cable, DVD or video game.

have you tried a system restore to get your resolution back?
You may then try to take a different path in fixing your problem.
if you cant system restore try installing the previous driver you had.
could you post up what your "computer problems" were exactly?
the more info the better*
We may know another solution for it other than updating your driver and losing you resolution options

The convergence IC has gone out and is located on the Main bd or the Power supply bd depending on the specific model and must be replaced and a Full convergence alignment must be performed to return your tv to a watchable condition. Only a Samsung trained tech can do this.

After reviewing the service manual for this set, the problem is is in the DIGITAL BOARD. To get the right Digital Board you will need the Version number of the TV.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.
When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
