Any electricians/AV people here?, Need help with a TV Options

[SwissFerdi]

Long story short, I came upon this old (I assume) 49" Hitachi tube TV.. It was going to the trash anyway, so I figured I might be able to fix it, it's a pretty nicely sized screen after all. The whole unit is physically fine, and the screen is straight. However, the display itself is a bit messed up, as it seems to be concave (middle of the screen is farther in than the outside). The colors, however, are entirely fine. I will pull off the back of the unit tomorrow to see if there's anything out of the ordinary that I can see.

You can see in this picture that everything has sort of a shadow.



And here, you can see that weird display error at the top.



Now I'm not inclined to make judgment of this, but what I see leads me to think that the lamp itself is fine, but the projection surface might be the problem. Any input on this would be appreciated. I can get better pics tomorrow if need be.

Alright, so I took off the back, and it seems like a pretty simple setup. The back cover contains the mirror where the image reflects from, which then goes through the plastic screen. The mirror is perfect and the plastic seems to be straight as well, but I'm not sure if that could be the problem. The projectors look fine as well, aren't loose, and don't seem like they've shifted.



The left projector is mounted differently, I thought it was loose at first.



And that's what the whole thing looks like inside. That projector housing (I assume all the wiring and everything is down there, nothing that would cause the problem I'm seeing) says Do Not Open, so I'll heed that warning. Unless anyone else has any input, I don't know what to do from here.
