SOURCE: -anyone know where I can find a convergence repair

There is a convergence button on the front of the tv. If that doesn't work, the kit is only available to authorized servicers. Contact the manufacturer for an authorized servicer. esupport.sony.com

Double vision with redness


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.

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.

My unit is 9 years old, almost 10 (in 2 months) and started the same a couple of months ago. The only way to fix it is to have them serviced by a tech and replace the projectors. Its just the age/use of the unit catching up with it.

Many resellers sold them with an offer to sell you an optional maintence service where they would fix/clean/replace the projectors for upto 5 years after purchase. I'm not sure if they even have the parts anymore since these tv's are no longer produced. After market repairs are likely to cost as much as or nearly as much as buying a new flat screen tv.

When the set turns off, does the red timer LED blink on the front of the set? If so, how many times does it blink? The number of blinks corresponds to the reason the set shut down.
