Bent picture The picture on my tv screen looks like it is bent. The info bar at the top of it has a rainbow shape but not a rainbow color effect. The words that are displayed on the sceen look doubled. I tried to use the manual converge menu but none of that seemed to help. Help please

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.

Ok thanx for telling me why the problem occurred =) ..now how do u fix it???

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.

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.

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.
