Projection sets have two very common problems outlined below.
The first common problem is convergence
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. The TV can also shut down when the convergence starts to fail.
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, RCA and others.
