Hi @sgesus welcome to the forum!
Typically, I give the Power Station a few minutes to warm up before turning on the high-voltage: just like a tube amp.
Do the checklists here:
- Won’t turn on (if you don’t see the green power light)
- No sound (this is definitely the case)
- Won’t switch to operate / no attenuation
Also, it would be useful to know your PS-100 serial number.
Regarding support:
The forum is the place for all support. Generally we can handle things here and when needed we get the shop involved we email them.
