My oscilloscope died the other day.
I was using it to look at the output of one of my Etherkit Si5351 breakout boards when it made a high pitched “pffft”, the waveform disappeared and a bunch of indicator lights came on.
Haven’t opened it up yet to see if I can spot anything wrong. The scope still turns on, but there’s no display. The indicator lights behave like the scope is working, but there’s nothing on the CRT. That could be a good sign.
Will be a while before I have some time to poke around the innards of the scope.
