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.
