There is no way to electrically test these ICs because they have so many more parts internally.
The way to pin point that they are defective is by looking the way the picture on your TV is behaving, if you are unable to converge all the colors using the remote; that will one indication that the STK392-560 are defective.
You might also have to measure some low value resistors nearby the ICs, because they become defective as well.
Let me know if you need further assistance.

This is a convergence problem that can be as simple as poor solder connections on the pins of the convergence ICs or defective ICs. If you can solder, you may be able to fix this yourself. If you wish to attempt the repair, update this and I'll provide additional details and instructions.

That depends on which part you will end up needing, without troubleshooting the set there is no way to tell which part or parts are defective.

My sony tv will not stay on


If you replace the lamp and need to reset the Lamp Timer Reset procedure is: With The Set In Standby Press Display, 5, Vol Up, Power on the remote control Press Jump 3. Or, To Display The Lamp Time Press 2 Nine Times. To Reset Press 3, Mute, Enter. One of these should work on your model. Make sure you replace the bulb first. There is a possibility that the ballast could be damaged by a defective bulb as well.
