Currently the screen is not aligned correctly. The bottom of the screen when you touch focus does not allow the line towards the left of the screen to properly align. The picture and screen are there but the picture is distorted. Is this something expensive?

Alot of rear projection t.v.'s have a convergence option in the menu on the t.v. There you can set the try to set the colors back how their supposed to. Mine has a cross in the middle of the screen and you just have to try to get all 3 colors to line up. Unfortunately, the actual lens inside mine has to be aligned so it doesnt work. Just something to try though, hope it helps.
you have a convergence problem it will require a couple new ics its best to replace as a pair stk392-110 although i recommed using the stk392-150 as a replacement and also there are some jumpers that should be resolderd on those boards to assure continued operation hope this helps you
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

Convergence amp ic bad http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html http://www.hdtvoice.com/voice/showthread.php?t=28929 Or send to ptscorp.com http://www.hdtvoice.com/voice/index.php?s
1)I have yet to learn any advantage to replacing -110's with -150's
I think there is a misconception that increasing numbers =
better,more durable results....Actually, using OEM or better
quality should be most important.Generics from any source
tend to be seconds,thirds, junk ! Name brand are first quality
2)Check B+ feed resistors next to convergence IC's = burnt ?
3)Solder wire jumpers on signal board = 008,010,017,600,etc.
