Re: the touch focus
Will the red align in all 4 directions in the other areas of the screen? If it moves in all 4 directions everywhere but one section its probaly a resistor near your convergence amplifiers. If the red wont move in all 4 directions anywhere, then its your Convergence amp ICs faulty. Cost about 20.00. Hope this helps.

This is a problem with the convergence circuit. If you can solder, you can repair this yourself. First try and resolder the pins on the existing convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs.
You have a convergence problem for sure. This can be a pretty complicated repair. It takes more than just replacing parts. You will have an electrical service menu adjustment that will have to be done so that magic focus will work properly. You may want to contact a repair shop. Thanks
Replace the convergence amps and test and replace any or all of the 2.2ohm resistors in the yoke return path out in front of the amps. This unit takes two STK392-110 Sanyo originals, DO NOT GET CHINESE KNOCK-OFFS... Buy them from Acme sales out of Florida and you can be assured they're originals.

You can repair it yourself by replacing both STK392-110 Convergence ICs. You can get replacement ICs at the following link with free instalation instructions . Heres the link. http://servicemanuals.vstore.ca/
I just got finished repairing the same model . The convergence modules are bad cost of repair is 250.00 for a service center to fix. My advice would be call your local service center tell them what i told you bad convergence ic and ask them how much they charge,
One of your convergence IC's has burned out and needs to be replaced. A good rule here is to go ahead and replace both STK392-110 IC's with the new improved STK392-150's. If you have never replaced convergence IC's and realigned convergence circuits, allow a qualified tech to handle it for you.
