I have a Mitsubishi WS-65807 Projection Tv and while I was watching a program the picture went to a black screen. The audio works fine and when I go to the Menu it shows up fine. Any input as to the problem would be appreciated.

Thats usually a vertical issue since the menu still works. I would check the solder on the vertical IC and also the Vertical yoke plug pins. Often solder can develop a small crack around the pins and resoldering will usually fix the issue in most cases. The other item could be a leaky CRT has dripped some coolant on some of the components in the vertical circuit so I always check the board for any sign of a clear sticky residule on the boards which indicate dripping CRT coolant.
