I've got a projection tv here with the blue gun having trouble.

It seems that theres some kind of curl.. or dip in the top. the bottom lines
up perfectly fine. Is this some kind of yoke problem? I can't imagine what
else would affect a tube like that..

The problem follows the tube when i switch the color inputs or the yoke
connectors..

Here's a picture to explain it better.
