Panasonic rear projection set worth salvaging?

[dr.ido]

A friend has asked me to look at a rear projection set that one of their friends picked up. They were told it was working, but I wouldn't describe this as working. I have no experience with rear projection sets, so I am not sure if I am getting in over my head. I will be paid for for parts, but this will be done as a favour.



This is the onscreen image. It's fuzzy, underscanned, and CRTs are obviously far out of alignment.



Removing the back I can see the position adjustments on the sides of the CRTs, but I can't work out how to adjust them as back/mirror has to be removed to get at them. Looking directly into the CRTs the images are sharper, but underscanned and bowed in at the sides. There is also a black strip across the red CRT that isn't on the other CRTs. Is this supposed to be there?

Where should I go looking for the bowed in sides and underscanning problem? So far I've found a couple of test points and the voltages are spot on. Should I back out while the getting is good?

There's an even older Toshiba front projection set kicking around as well, but I haven't even looked at that yet. I've got enough problems finding room for conventional sets let alone projection sets.
