There you have it Ron M. the TV is fixed and done without your complete assistance. There are plenty of other people out there that can help you fix something without having to deal with an arrogant a@$ hole like you. If anyone out there would like help with the same repair I hope this helps. All I can tell you is continue to search online and you will find the answer. Good luck. Bye Ron.

>> Well even though I know how you love it Ron I went and jumpped ahead << and used the electrical focus controls as listed on page 16 of the manual. That did the trick and I was able to adjust the sceen until the blue dissapeared. It looks like I just have to use the menu to adjust the final picture quality and it should be good. I really appreciate the advise and your time, though you really need to chill out alittle bit. Thanks again.

I took your advice & am enjoying a DELICIOUS Strawberry Margarita......

(Edited quote) replace the STK392-150 convergence chips that were already installed in the tv. I did that and also discovered resistor R7056 which is a 2.2 ohm @ 2 watt metal film resistor burnt out. ... I'm into it for about $70.00. I'm not really sure I had to replace the convergence chips because the same problem I had before still existed.
