The red convergence ( horizontal ) swags downward from the middle of the screen to the right side. It is a none adjustable problem. Is this a I.C. problem or replace a complete board ? Any solution ?
Red shadows on the screen. Running auto convergence will not correct.

have pts rebuild the board which will cost around $130, www.ptscorp.com, or replace the stk392-110 x 2 located on the convergence panel.

PCB's when available,are expensive.Replace convergence IC(s), re-adjust and you are good to go!
view of board removed from set--back side; note the two black chips to the left.

have the same problem to where the picture looks almost in 3-D. Have a slight convergance peroblem to the bottom of the screen, any solution would be greatly appricated. Greg
I have the same problem, happened to be watching it when it happened 03/17/08. the Blue and Green has no problem auto convergence fixing but the red will not and when I manually try to adjust the red, it will move up and down in the squares but will not adjust left and right (like the blue does). Have removed the front panel and located a focus and brightness and have turned it way down for now (the red) but it looks like I am looking through water to see the picture now ,..... how do I get the red convergence to be able to shift manually left and right ???
