Protection Check DSP Voltage
Hello everybody,

I have a problem with my Harman Kardon HK3490,just been repaired cause i had a cracking left Channel.

Yesterday i picked it up and connected to everyting and when i tryed to put it on BANG not a bang but he was going directly in Protection mode Check DSP Voltage.

Somebody knows what this means?

Thanks and greetings from me and Amsterdam (Neth).
