I bought the LP220 projector last summer on eBay, and it worked for a while. But after a few months, the image started flickering really badly, it looked like an old-fashioned projector with the film coming off the spool, it was flashing up and down and all over the place. I realized that this only happens from the S-video input, and the red-white-yellow input. If I plug in from the computer, the image is fine, but goes blank after a while. (That's another problem, but I never really use it from the computer anyway, only from DVD player for movies.) So I figure something must be wrong with the actual plugs(?) but not actually with the lamp, seeing as the image doesn't flicker from every input. Has anybody experienced anything like this before, or know what it might be? Thanks, John
