I have a HP 8591EM EMC analyzer. The top half of the top line of the display is cut off making it impossible to read out results. (Photo attached) Basically, several pixel rows are missing.
Before I get too deep into trying to fix this, I'm wondering if this is something that has to do with CRT vertical size/position that can be fixed by tweaking a pot, or is it a problem with whichever module is generating the video signal? If the latter, is it likely to be an easy fix?
There are menu options that move the display in the vertical direction, but don't change how many pixel rows are displayed.
Thanks!
