You really need to be persistent. I went on the Panasonic customer support webseite and started a web exchange. The first two attempts ended with "call your local authorized service tech" , etc. The third time, I described the prolem again and asked if the authorized tech would have the tool to fix the eprom if that was the cause of the problem. They finally gave me a name for their scheduling department and said they would pay for the diagnosis. I was pretty happy about that, but even happier when they said that this was a known problem and they would pay for the repair as well. They scheduled a service call. The techs came and fixed the eprom error with their tool within 1/2 hour. That was about 5 weeks ago, and all looks good so far.

The repair isn't too complicated if you're comfortable working with a soldering iron. Sounds like one of the "guns" is shot. The chips that need replacing are attached to the heatsink on the convergence board. The reason for replacing both chips is if you're going to bother to take the board out and replace one bad chip, that is the best time to replace the other older chip. The link below is to step by step instructions including pictures of the repair. You can check it out to see if you want to try it. If not, the repair is expensive (between 250-400) depending on the repairman. Best of luck with your convergence problem.

WITH AN ORIGINAL SONY REMOTE HIT THE DISPLAY BUTTON TO REMOVE THE INPUT ON SCREEN DISPLAY---IF YOU leave it on long enough it will burn that image into one or more of the 3 picture Tubes.
ALMOST ANY SONY TV REMOTE WILL WORK FOR THIS FUNCTION.
