Problem with focus (severe problem on upper left

65" XWX HDTV: Problem with focus (severe problem showing on upper left of screen severe shadows on upper left of screen, off by 2-3 inches). Tried to fix it using Magic Focus, but it didn't fix it, and the Magic Focus cycle did not complete due to the severity of the problem. In fact, it took me to some weird DOS-looking screen. Do I need to replace a projection "gun" or whatever it's called?

The Convergence circuit needs to be repaired.
There is a pair of Convergence IC's that need to be replaced. Best thing to do is to call a repair facility unless you have a solid back ground in Projection repair.
Hope this helps,

Picture is distorted from center on my 65


You do have a failure in the convergence circuit of your set. If you are good at soldering you can replace the IC's yourself. They are on the large circuit board on the left side of the set looking from the back, and attached to a large aluminum heat sink. If you don't feel comfortable doing that, I reccomend removing the board and sending it to PTS corp in Indiana. They are pretty reasonable repairing boards, and a lot less than buying a new one.
