Question about Sony KP-43T70 43" Rear Projection Television
Since you say that this happened after moving the unit (and bumping it into a wall) it would seem to be worth looking at all interconnections from board to board to make sure that they are seated securely and properly. It could be as simple as a loose wire. If you don't find any problems with the connections I would look for broken solder joints on all boards paying close attention to the video board. A magnifying device will be necessary for this or you could resolder all the connections on the video board, if you know how to properly solder. Remember safety either way. If neither of these suggestions work you will probably need a qualified tech to find the problem as it could be just about anything. Good luck.
