Red convergence problem


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.

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.

Scratch Screen


Sorry about the late posting. The protective screen can be purchased from Tritronicsinc.com using the part number KR2074. This will cost $80.36 plus shipping. This should be a straightforward replacement. The instructions are included with the screen.

Hope this helps,
Dan

Picture is dim and blurry


The screen probably needs to be degaussed, which will require either a degausser or a technician. Try turning the television off, and then unplugging it from the wall outlet. Then replug after 30 seconds and turn it back on. Also, try plugging any cables from a cable or satellite box into another set of in-ports on the back. If the problem persists, the screen needs to be degaussed.
