Projection TV
sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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
Common Symptoms include....
Here are some photos
Here is a quick test....
Using your original remote go-to the settings menu then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move RED and BLUE in all directions - up, down, left, and right.
If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.
