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.

Wait is this a rear projection TV or a Cathode Ray Tube Television? I know a little about TV repair but please be careful when you have the back open CRTs have very high voltages in some areas if you touch the wrong spot you could be in trouble.
