I Replaced stk-392-110 (2) , TV finally comes on again! When I adjust the convergence for green center line, things are ok. When I try to adjust the center + for red it will not move right or left only up and down (It needs to move right) while blue adjusts just fine. When I have to adjust red/blue convergence on outer screen area, I am able to get the 1, 4, 7 side of screen lined up but again cannot move red right as it needs to (only up and down). Any Thoughts?
Check the resistors in the red convergence circuit right next to the Ics you will need to lift one side of the resistor out of circuit to acurately check them but usually one or two resistors will be opened when the ICs go out
the resistors that I am refering to are located right next to the Convergence ICs heat sinks they will all be identical and be around 10 or 12 resistors. You will have to unsolder one side of each resistor to check them as they cant be checked in circuit
Yes then just check them with an ohms meter if they dont register then they are open and will need to be replaced. Just put the meter leads on each end of the resistor body after you lift one side out of circuit to take the resistance reading
Those are not available at radio shack I would try the following link. The dont list them all as they have so many but leave them an email. You need 2.2 ohm 2watt 5% tolerance Metal film resistors. Heres the link.

Not sure where the resistors are located u are referring to. I do not see anything that i can lift without de-souldering. please help!
How will I know if they are open, will it matter what side I pull? If none are open could there still be a problem and should I replace them all? I am assuming u are referring to pulling part #'s R7011 and the like right?
Thanks, where can I order new resistors?
