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.

Yeah I know almost nothing about rear projection TV's but the problem seems to me to be in the electronics rather then the projectors. If a projector had problems only one color would be affected. With high voltages its very important to let the capacitors inside discharge so you don't get shocked. If you don't know what you're doing it's best to leave it alone. Did you try googling the model number maybe someone already knows the solution?
