Your
TV most likely has one or more possible problems.
Problem #1: Convergence Chip Failure ( common problem )
Here are some of the most common symptoms and example
photos of a convergence problem
- 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 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 them 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.
Solution #1
You need to replace the convergence chips and convergence resistors. Check the site
www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a
photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
Problem #2 CRT Fluid is Cloudy
Projection
TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around
images.

Solution #2
What you will need to do is replace the coolant and clean the crt. You can get a repair kit from
www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
I'm having these red vertical lines, which appear as a shadowing to the left of text, and along the borders of certain tones when watching a movie. Is this the same as the convergence error? And if so, is there any advice on the process of moving the panels so that they provide a balanced image?
Note that this shadowing happens to the menu as well, with nothing attached, so its definitely NOT a cable problem.
Thanks!
Same problem on my NEC and getting worse. How to do this adjustment?
