Its almost always a convergance inverter that has burned out. The IC chips as they are called aren't too cheap, Even the repair shop would suggest a new tv as a cheaper route in the long run. To make your set reliable again the convergance board needs to be rebuilt with all new chips, and pico fuses.

Mitsubishi VS-45609 Blue layer is distorted and seperated

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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
