Facing TV Problems? Ask a TV Technician.
No, that's normally not the DLP failing. I'd suspect the board that your DLP is mounted on, it's called the DMD board (aka formatter board).
You see a big thick BLACK cable in the center of your TV? That is connected to the DMD board located in the center of your TV set. Unscrew that cable, insert it 3 - 5 time to knock any corrosion off those pins. It may restore your picture. Take a look at this website, that board in the picture is your formatter board. That cable/connector is seen in the picture in the upper right side of that board.
Ok, let's run some more tests to see if we can isolate the problem and make sure it's the formatter -- activate the TV's menu, make sure the menu has the same black bar in it, ok? The menu is the last part of the TV's picture circuits before it gets sent to the formatter.
Per Mitsubishi tech site -
Cause 11. The menu is affected; suspect the FMT PCB part # *****
Vertical Lines or Bars
Cause 11. May be only be only on half of screen, suspect the Optical Engine part # 938P017020
You seem to have the bars on your screen more than the Pixellation (blocks of frozen picture).
I doubt the formatter is the failure, when I compare Mitsubishi's information.
