Television and Home Theater

I have a wd62725 with black lines running from top to bottom, but the lines are not solid all the way through and the move around. I think the problem is in the PWB-DM board. I did not take it out yet. Am I starting in the right spot???

I have a 4 year old Panasonic DLP and there is a rectangular shaped discoloration (yellow) in the middle of the screen.   It is a failrly large area (about 24 wide by 12 high).  I have replaced the bulb and it did not fix the problem. It never moves or grows and has become a distraction now that I know it is there. Any thoughts?

I am an unlucky Toshiba owner that also happens to have the "zigzag" issue that is remedied by replacing the scan converter/hyperboard.  I noticed in the Toshiba Model 4283 thread that you had mentioned that you fix those boards...that would be ABSOFREAKINLUTELY amazing.  That part or its' equivalent is still available anywhere.  I am in the difficult position of needing to get this fixed or my wife will kill me...no joke, she has already shown me the funeral arrangements
