HP 54600A digital scope picture squashed
 

Hi all,

If you have an HP 54600A 'digitizing oscilloscope' which is experiencing a vertically squashed picture on the monochrome video monitor, make your way to the monitor PCB, locate an innocuous little 10uF/16V electrolytic (typically C608 on the PCBs on which it tends to go) and change it. That fixed mine.

There is good online availability of information for this unit generally, but the monitor diagram included in all packages that I could find does not match the one fitted in my unit: Obviously, HP / Agilent sourced monitors from a few different places.

However, mine (not the one featured in the diagrams) seems to be the version which always develops this problem - therefore, if you have this problem, you probably have the same monitor chassis as I do, in which case C608 is your prime suspect.
