You'll have to forgive my wording, I'm new at forums. Anyway my Z2 seems to now have a red registation problem where any lines on the screen seem to have a red drop shadow. I've gone through the settings using the manual but there isn't anything like this problem mentioned. Is there a code (like the TV repair man would use to get into the internal settings of a CRT) or some way of getting into the Z2's internal settings, if there are any? Could this be a sign my bulb is dying, it's got 1970 hours of running time? Any help would be appreciated.
