My HP 54501A scope has developed the vertical jitters. The trace (on all four channels) almost continuously, moves up and down on the screen. I have verified that the power supply is stable and voltages are spot-on. In addition to this problem, the scope now randomly shuts off (including the fan) and then immediately restarts.
Any ideas and suggestions will be appreciated.
Thanks,
Dave
