If picture looks 3d and will not adjust (select convergence in the customer menu) one or both of the STK-392-120 CONVERGENCE CHIPS ARE BAD.

What needs to be done if this is case is to replace both chips and any of the 6.8 ohm protect resistors around them that are discolored or bad---I did one of these sets a few days ago--repair takes about a hour.

The parts for this repair cost less than 20 dollars if you buy them on EBAY. The real question is are you able to do the repair yourself?

If yes, I can give you instructions--it involves getting at the chips--unsoldering all 18 pins on both--checking the resistors around them etc.

If you cannot do this repair--shop around your area--most shops get 300-400 for this repair---the one I did the other day I charged 250 total---in home parts, labor, house call--everything.

MAKE SURE IF YOU GET SOMEONE TO DO THIS THEY REPLACE BOTH CHIPS! Some idiots will come out and just replace one chip---the set is going to have the same problem in a few months----

Once both are replaced and the set adjusted--it will not have this problem again for 5-8 years.

Clearly I do not know if you can do this repair---I am here to help people-IF YOU HAVE ANY QUESTIONS OR NEED HELP---do not hesitate to ask me here .....

Regards, SD TECH
