I have an RCA 52" home theatre projection TV, model # P46813BL. At first it had black lines at the top and bottom, almost like a letterbox movie, then it started to get one directly through the middle after it had been on for a while. Then today, I removed the rear lower cover and cleaned a LOT of dust off of the circuit boards (of course being very careful not to actually touch anything), then when I turned it back on the lines were almost all the way gone. So I followed the service papers instructions as to how to bring up the service menu to make sure the vert., horiz., and center alignments were right, and lo and behold, as soon as the alignment grid came on the screen, and I touched the ch + to adjust it, like the paper said, the picture went completely out, and all I have now is sound. PLEASE HELP!!! What could have caused this, and what can I do to fix it? thanks, BAD TO WORSE.
