I actually have 2 of these models at the same time. On one the red horizontal adjust has no effect for center convergence, red vertical is fine as are the blue adjustments. I replaced the ic's twice with no change. Suggestions?? On the second set the red vertical is down on the left and tilted up on the right however red horizontal and vertical do adjust to center over the blue and green. I changed the red ic twice with no improvement. I also substituted the digital convergence module with no change. Thank you for the right answers to my questions. Mike at the Video Center.
