I posted this to the home theater group too, but thought here might
also be worth a shot.

I have a Pioneer SD-P5183 rear projection TV that doesn't work
properly after moving house. The red gun is way out of convergence on
the bottom 3 cross hairs. The top and middle 3 are fine and the blue
and green guns are fine across all 9 points.

The convergence control on the remote doesn't seem to help. I took
the back and the screen off the set hoping to find some manual
adjustment controls, but can't find anything.

The red gun is probably a good 1.5" too high. The mirror looks to be
in place and all 3 colours are in focus.

Can anyone offer any advice?
