We purchased the convergence repair kit for our sony projection tv and complete the repair, but the problem is worse. We tried to adjust the convergence using the menu on the tv, but nothing changes. Does anyone know what is happening?

You will need two STK392-560 Convergence ICs and you will also need two of the 3.5 amp pico fuses as Sonys will always blow at least two of the Pico fuses. You can get replacement ICs and Pico fuses at the fiollowing link and they provide free instalation instructions. Heres the link.

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.
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.
Picture of a set that needs the fluid changed.

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.
