Below are two of the most common problems encountered with projection TV
sets. Problem #1 - CONVERGENCE PROBLEM
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, and others. You can get a convergenece repair kit from the link below. Common Symptoms include....
- Screen looks 3D
- Colors don't line up
- One or more colors can't be adjusted when using the convergence menu.
- Screen is bowed or warped.
- TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos
of convergence problems. 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.
Note: If you TV has as flash focus
or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solutionCONVERGENCE SOLUTION
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
