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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

On my HD1080 Mitsubishi projection flat screen 55809 the picture is bowed on top and bottem and it look as if the projectors themselves are offset, but the picture is clearer as you come toward the center....


It could be one of two things: Either a bad solder joint or convergence IC failure.

Convergence IC failure is very common. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless

You have either bad convergence ICs or just bad grounds on the IC. I would go ahead and replace the ICs and check those small ohm resistors, as you have to pull the signal board out anyway. For futher instructions see the website www.TvRepairKits.com. They may have what you are looking for. Be sure you have the TV model number next to you. Thanks for asking and show a few hands of support!

most likely the convergence Ics have failed. Check F9a04 and F9A05 pico fuses if they are blown you will need to replace them and the convergence Ics.They are located on the center board they are green and look like resistors without the color band. see the photoa193b32.jpg82b89b8.jpg

I have a similar problem. I have tried to fix the convergence via the remote and that has not helped. My three colors are separated and the edge of the picture is bent in toward the center. I am going to try a hard reset but i suspect the convergence IC are fried. Since the set is not HD, I will probably replace it if the hard reset does not work.
