I had the problem on a 50" wega set I got for free due to it not working. The bulb was loose, reseated it, came to life. But there were colored "bars" at the top and bottom of the screen. I took the optical unit apart, and "rotated" the first prism 180 degrees. With my flashlight shining through the light box, I could see the bars and blobs disappear when i moved the prism around. Put it all back together, and bam! Had a beautiful picture. Took about an hour to do, and now it lives in my den and we watch movies on it all the time.
