Question about Hitachi 50GX30B 50". Rear Projection Television
Ghosting on laft side, tried Array alignment and can adjust all 9 '+' signs except the middle left will not move far enough. The red '+' sign will not shift far enough to align with the others. Only Blue and Red can be adjusted, cannot move the Green or White '+' signs. The top row also seemed to be scewed and the 'box' around the '+' signs is actually leaning to the right so the adjustments are close but not exact due to the skew. Any ideas to fix is appreciated.
One of your convergence IC's has burned out and needs to be replaced. A good rule here is to go ahead and replace both STK392-110 IC's with the new improved STK392-150's. If you have never replaced convergence IC's and realigned convergence circuits, allow a qualified tech to handle it for you.

You will need to replace the convergence IC inside the TV set.
