I have same issue as well. What is the part number for the ICs and where is the IC located at?

Posted on Oct 23, 2008

Yeah, it is convergence. You can try a IC replacement yourself if you can solder and hour 3-5 hours to spare. Parts are $12-$60, depending on brand and quality. There are a few places that sell a repaired board for $140.00 and up.

You might want to check the light installation to make sure it is seated properly and there is no dust build up around it or the reflector. Have you changed it recently?

It's probably the magnets on the neck of each CRT that moved since you removed them or the CRTs weren't put back in the exact orientation . Use a white paint pen to mark each one as they are now. If there's a clamp or two metal rings that locks them in place you can try rotating them as a group (their location up and down the neck is also critical).  If not you will have to adjust them individually and then do a complete convergence adjustment. That's a big task. Good luck.

Green drooper.

that is a convergence fail. yes you will need to replace the 2 convergence ICs as well as any burnt resistor off the blue vertical convergence yoke. which will be a connector most likely with a blue mark on it. the convergence ICs will located on the right hand side of the chassis screwed into the 2 large heat sinks.

Sounds like your convergence amps are probably bad. Check out and see if you have similar bowing between red and green when you try multipoint convergence. If so, you'll need new convergence amps, part STK392-120. Most people who are handy with a soldering iron can replace these parts in a couple hours.
