Hello,

thanks for your help, I've got a Service Manual for the Scope. But now
I've got 2 new Problems:
- the line fuse was blown after a short time when I switched on the
scope. Which Units should I disconnect for the LV - Test?
- How should I test the HV - unit? It's installed behind a shield and
two other PCBs are mounted on the shield.

I also think the Problem is in the HV - section, because the crackling
came from this direction.

Greetings,
Holger
