SOURCE: bad color
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
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.
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.
Picture of a set that needs the fluid changed.

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.

This model uses two convergence IC's----if 3 D one or both are bad.
Most of the time this set uses either two of the STK-392-110 OR THE STK-392-150 CHIPS.
Both chips and any bad protection resistors around them need to be replaced and the set adjusted.
If you are able to do the repair yourself total parts cost will be under 30 dollars.
Some history for you:
This set like all rear projection tube type sets uses two chips---the ones in your set are Black in color--about 2 1/2 inches wide X 1 1/2 inches tall and are on either one large or two smaller heat sinks with fins on them.
When the chips are installed a white grease called heat sink compound is applied to the metal back of each---the grease transfers heat from the chip quickly to the metal it is bolted to.
After some years the grease dries out from the heat and one of the chips goes instantly.
You can buy a pair of the chips for your set on Ebay for less than 15 dollars plus shipping--
If you cannot do the repair yourself--shop around your area---most shops charge 300-400 for this type of repair. Whoever you get to do it make sure BOTH chips are replaced or you will have the same problem in a few months.
If you open the set and locate the chips---they will have the full STK number printed on them in white letters----there are about 12 resistors around them that need to be looked at--if any are discolored they need to be replaced.
If a shop says it HAS TO GO TO THE SHOP keep looking as any good tech can do this repair right in your home in about 1 hour---I know as I have done hundreds of them.
IF you can solder and are handy I will give you general instructions on how to do the repair and what you need---some people I talk to can either do it or have a friend who can do it for them---let me know
I can tell you what you will need aside from the parts and how to proceed with the fix---
If all this helped rate this solution---I do this here for free.
IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW--I am here to help people.
