Lloyd, convergence IC`s have failed, usually STK392-110`s mounted on large aluminum heat sink with the above number stamped on the front, also look for any slightly burnt resistors located in front of the IC`s, not an easy fix for the average joe, you`ll need a good knowledge of soldering and an accurate volt meter to measure the resistors, any questions? e-mail me, BMW Rider

The main coupling capacitor feeding the frame scan coils has failed or the output stage on the frame stage has failed due to dry capacitors or dry joints.
Fault finding and components are not a problem and yes it is very repairable. Any technician that knows how television works can repair this standard frame output stage.
I hope you find a good technician.

Hi,it seems you are experimenting a light engine problem.This is how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo So basically the 3 Lcd chips that create the colors and image is going bad and thats why you get that color discoloration.Contact Hitachi or look for your light engine online.God bless you and your house!

You have a failure in the convergence circuit. There's a circuit board ( the convergence board) which has 3 IC'c on it that drive yokes on each of the picture tubes red-green- blue. You probably lost power to these IC's or one or more may have opened up. Sometimes poor solder joints on these IC's will develop causing loss of convergence. Hope this gives you an idea as to where you problem is. Stargazer
