Here are some of the most common symptoms and example photos of a convergence problem.
This is a very common failure on Projection TV sets.
- 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.
Here are some photos of convergence problems.
Here is a quick test....
Using your original remote go-to the tv
settings 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 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 solution
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing or you can call in a pro.
