1. Are all the sensors clean?
2. Have any of the sensors moved?
3. Is the H and V size exactly to factory specification? (if size is off, the auto converge will not work)
4. If the sensors plug in, did you physically remove the left sensors and plug them into the other side of the screen? Then if the problem moved, move the sensors back one at a time.
5. Finally you need to verify each sensor output at the convergence module.

Most common issue we ever saw was #1 and #3. People would get into service mode and adjust in the overscan. The set has to overscan a very specific amount in order for the magic focus to work.

A technican error was to forget to do the magic focus initialization after manually converging the set. The magic focus has to initialize the proper convergence values and this must be performed after any manual service mode convergence adjustments.
