Question about Mitsubishi WS-55511 55" Rear Projection Television
I have a 7 year old 1080p rear projection 55" tv. The image began ghosting. There is the normal picture with a "red ghost" behind slighlty shifted by about 2 inches. This occurs on all inputs and via cable, dvd, etc... so it is definitely not the input device. It appears as though all the colors are still there (red green and blue), but maybe one shifted??? i was watching the tv while it happened. it first did it for about a minte then self fixed itself so i thought maybe it was the cable tv signal. Then it did it again and is now permenent. it makes tv watching painful...
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...
