Default Re: Sharp MZ-80K help needed on repair

Images 1 and 3 didn't really catch what we are looking for, maybe try again on those ones, they are likely to stay mainly in one state and only pulse to the other state for a very short time, so try to catch a whole one of those pulses on each of those pins.

Are the controls, especially the 'H-Hold' controls exposed on the rear of the monitor, in other words can you adjust them from outside? If so try adjusting 'H-Hold' gently up and down from its present setting when you have the 'bent top' problem on the display. If turning it left or right a bit cures the bent top line, leave it like that. If it makes no difference return it to exactly where it was.
