Below are two of the most common problems encountered with projection TV
sets. Problem #1 - CONVERGENCE PROBLEM
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.
