Your
TV most likely has one of two 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 was just given a 55" magnavox projection tv. The picture is great, but it seems to have a band of soft green and reddish orange areas through the center from top to bottom. The discolored areas are about 5 to 6 inches wide. During dark images they are hardly noticable but they really show when the screen is bright or light colored. It may be important to note that we transported this tv on a flatbed trailer over a very rough road. The tv was transported up right, but I'm wondering if we may have jostled something loose inside our is this another issue. Any advice would be greatly appreciated.
