Hello,
while taking a measurement my HP53131a counter sparked and became quiet.
After tear down I found both 3A/240V fuses in the PSU burnt. Before pluging a
new set of fuses, is there a knowledge of a common problem that couses a
shortcircuit at the HV side?
The counter has also a spilage at the bottom side of the mainboard, but as it
is same as in Gerry Sweeney's youtube video (HP 53131A Teardown and Spillage
Clean-Up <https://www.youtube.com/watch?v=czCLXrUPX0o>) and his counter still
works I assume it is not related. Is it a good practice to get it cleaned?
