Pioneer rear projection p4553 has a black line on the bottom of the screen and I need to find the adjustment to roll the picture down. Called customer service and a service manuel is no longer available. Removed back panels, cleaned inside of unit and tv works great.

Vacuumed the dust from circuit boards and just inside the cabinet, then cleaned the lens on the projectors. TV has always worked fine, cleaner picture now, but need to roll the picture down to get the full picture on the screen.

I don't have any info on this set,but if it's an older pioneer, then it should have a vertical and horizontal size control on it.Look for a small adjustable pot usually on the sweep board.They will be labeled.
