    My tv also looks doubled and I also tried to fix with the red blue and yellow but it didn't work. It looked like the main plus sign was the one that was curved I got it to where I can see the tv ok on regular channels ( I mean you can still see it curve, but it looks a little better) although on HD channels there is no way of fixing it you see red and double all kinds of stuff.

The convergence circuits straighten out the edges of the picture, putting the 3 colors exactly where they should be for the picture to look normal. There are usually 2 large IC's that handle the 6 convergence channels and if one of them burns out then one of the colors bends dramatically. If the power supply for the convergence circuits stops working, then all 3 colors bend in, the colors do not line up with each other and the image looks almost 3D, and the adjustments in the convergence menu will have no effect. I would bet that is the case with your set - the convergence power supply has quit working. If you do not have experience troubleshooting power supplies and realigning convergence circuits in projection TV's then allow a qualified tech to handle it for you.

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.

Not sure if you fixed your problem already. But the answer is a color convergence problem. You can try adjusting manually via the remote and if that doesn't work it is most likely the two main IC chips that control the color convergeance. It is also possible that not only the IC chips have gone bad but also there are a couple of resistors that usually burn out with the ICs as well. They will need to be replaced. This isn't something that I would attempt on your own. Typically a TV technician will charge between 300 and 400 to fix at your house.
