TV set is about 5 ys old, and it looks kind of like 3-d tried the touch focus and get error, tried the manual focus and can not move red left or right. I need help. Thanks
Also,check micro fuses F851,F852,etc.
and with a good digital meter, check resistors feeding B+ to
convergence circuit.
I have been using Stk392-110T made by Toshiba with no re-calls.Hitachi also has an upgrade IC.
And be sure to check your soldering of IC pins--good connect,
with no short.....T.
One of your convergence IC's has burned out and needs to be replaced. A good rule here is to go ahead and replace both STK392-110 IC's with the new improved STK392-150's. If you have never replaced convergence IC's and realigned convergence circuits, allow a qualified tech to handle it for you.

I am totally lost I opened the back of my big screen and could not tell where the IC's chips are. I would like to see pics and diagrams if possible. Thanks
