My cousin has a Toshiba tp48c50 rear projection tv that has a geometry
problem with the red tube. The picture is good in the center but twards the
edges the red is bent in like the trapazoid adjustment needs to be adjusted.
He called me thinking he needed a new red tube and I told him that it is
probably something else since it isn't dim and it is still in focus.

Does anybody have any ideas where to start with this?

Repair the convergence circuit, probably the red output, and realign
the convergence using a test pattern generator and alignment manual
procedure.
