Convergence amps need repair. Requires troubleshooting with meters, and soldering with new parts. A more common problem on RPTVs.

The picture is out of focus and showing double images in different colors.


If picture looks 3d and will not adjust in the customer menu (convergence) the STK-393-110 this set uses is bad.

This is quite common and the part on EBAY sells for about 15 dollars.

The good news is this can be a do it yourself repair. I have available start to finish, step by step instructions for this repair in this set---takes about 1 hour.

Let me know if you want the instructions and I will get them for you for free.

If this information told you something you did not know or helped you rate this solution as very helpful as I do this here for free.

Picture problem with rca 52 inch hdtv colors split not in focus


Hello, If your picture looks like a "3D image" you need convergence IC's . Red and or blue picture is not converging on top of the green picture. They are mounted on large, finned heat sinks. The # on the IC's starts with "STK-" followed by numbers.They are available through tritronicsinc.com for $15 to $35 each. Good luck.
