They are Big Black ICs will have STK on them they are startup and convergence ICs They control set to turn on and off and convergence. Look for board that has them on it.2 of them together. If they are 110s use 180s ,Let me know what # on STKs you have.

Yes, your Convergence ICs have failed. Replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu.

As stated in your response to another person (Hitachi 43UWX10B)

Your post didn't get attached to the message in which you read the 'fix' for your set so the person who helped, will likely never see it.
You might try re-entering your brand/model info and sort through the results to find the original message.

Convergence problem

You need to replace the convergence Ics in this set and most likley have a resistor burnt in the red circuit. If you can solder yourself you can fix your tv for less than 50 dollars. Part number you need for the ICS is CZ00431 they are STK 392-110. Location Ik04 and 05. Like I said if you are going to do this yourself check all the resistors in this area.

   Chassis will need to come out==skill and/or experience needed.

3) Possible bad fuse device in power supply,check any/all.

4) Re-check alignment.


PS.Name brand IC's last longer than generics.
