Convergance- Red X will not move to make crosshairs white. Picture is doubled with red and blue. TV is a 55 in Mitsubishi VS55601.

Enter Service mode.. Press Menu -0-1-5-7 in quick succession . From there select the convergence option. You should see 3 crosshairs -Red, Blue and Green. Green is fixed but Red and blue can be moved. Align both of them with green and see if the issue resolves. If not Try moving them around and see if the problem is cleared. If not you may have the inevitable convegence IC problem and the IC needs to be replaced. Let me know if that is the case and I will give you the procedure.

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

To adjust manual convergence on your projection TV, follow theses steps:

1. Turn your TV on.

5. Select Convergence, and then press the joystick. The Manual Convergence screen appears.
6. Select Red, and then press the joystick. A series of crosshairs appears on the screen.
7. Select one of the outside crosshairs by moving the joystick up/down/right/left or by pressing the 2 (up), 4 (left), 6 (right), or 8 (down) buttons on your remote. The method you use depends on the model of remote you have. Note: You must do the outside crosshairs first.
   

1. In the crosshair you selected, if you can see a horizontal red line, use the CH up or CH down buttons to move the line so that it is superimposed on the horizontal center line of the crosshair. Note: Make the single horizontal line as white as possible.
   

1. In the crosshair you selected, if you can see a vertical red line, use the Vol + or Vol - buttons to move the line so that it is superimposed on the vertical center line of the crosshair. Note: Make the single vertical line as white as possible.

probably need to replace the convergence ICs inside the TV. The Ic is about 2" x 3" and mounted on large aluminum heatsink. Usually 2 or 3 (depends on model)
