You need to replace the two convergence ICs they are STK392-560 and you will also need about two 3.5 amp pico fuses. You can get replacement parts at the following link with free instalation instructions. Here is the link.

Colors are separated red, yellow and green so picture is blurred


lgray1010,

Try using the Flash Focus to/or manually try to dial in the convergence. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure on between $250.00 and $400.00 USD.

TRY THE MAGIC FOCUS BUTTON. IF THIS DOES NOT CORRECT THE PROBLEM YOU WILL NEED A SERVICER TO GO IN AND REPAIR CONNECTIONS OR REPLACE THE CONVERGENCE IC'S AND OR RESISTORS. AND READJUST CONVERGENCE IN THE SERVICE MODE.

Converge problem on a kp-65ws500 sony rear proyection tv


You can download a copy of the service manual that explains how to enter service mode and perform convergence of the red/blue/green guns, but unless you are comfortable doing something like this, you may be better off calling a good shop familiar with rear projection sets and getting a quote to have a convergence service performed.
