    42" Hitachi 51F500 rear projection tv

    The customer complains that the the video looks like it is in 3D, and there is green, blue and red on the screen within the picture. I don't have a scope, could this be a cap problem. I have a blue ESR meter. I also need the service manual and schematic. Where can I find it?

    If this is a rear-projection CRT set, it's probably bad STK convergence ICs.

      Thanks Tom. Are these parts available at digikey or mouser?

        Not that I'm aware of, but you can buy them from other online suppliers.

          tom, is it a good idea to buy the convergence repair kits or just the 2 STK ICs.

            Just check the resistors RK42,RK46,RK62,RK58,RK50,RK54 and fuses fk01 and fk02, make sure they are not open.
