Convergence -manual I am having a problem manually converging my tv. the touch picture button keeps saying error. When i try to do this manually,either the green lines are very far away from the blue and red and the blue and red stops before it even gets to the blue or I'm getting them there and it's still not doing anything. Also I am having a problem where the picture looks warped or wavy and doubled. It basically looks like it's in 3d.

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.

SOURCE: convergence problem

Common issue with all rear projection TVs is for the convergence correction circuitry to fail. Set needs new STKs and possibly some tight tolerance resistors..... if not a DIY definitely a problem for a shop.

SOURCE: slight convergence problem after changing convergence circuits

My experience has been that the resistors have fallen out of range. These aren't expensive and neither are the caps that surround this area. If you're pulling the board out to change the resistors, might as well change the caps, too. If you're strapped for cash, but have a multi-meter, you can test the caps and the resistors after they've been taken out of circuit to save a little green. Let me know if you need any help testing them; I'd be glad to help.

Absolutely! if the consumer control has failed to rectify the problem you need expert help. There are two control boards near the power supply 1 or both are involved and more than 90% of the time both of the boards have to be replace otherwise the problem will occur again in a short time.
It is not a DIY project for the unskilled as it has to be tuned correctly when it is installed.
Better to leave it to the professional
