I just replaced my colorwheel and bulb for my TV on my own which was fairly easy and took me a few hours. But when I put the TV back together, I now have a gap in the picture at the bottom of my screen, about two inches. I have been fooling around with it for the past 2 days and can't not figure out what the problem is. I don't think I shifted anything when working on it. The whole picture has just shifted up and I can't seem to bring it back down. The inside panels are in their right place and are screwed into place.
