No Output from Hegel H390

Hi All, need some help.

I have recently bought Hegel H390 integrated amplifier.

I connected it to a network via ethernet, upgraded firmware to latest one and opened my Roon. Roon immediately recognized Hegel as end point. Though to my surprise there where three Hegel end points. One Ethernet and two AirPlay ones. I enabled only Ethernet. Network on display immediately changed to Roon and displayed frequency rate of the flac file. However there is no output coming out to speakers. Played DSD file from Roon. Roon recoginized it is DSD input. Same result, no output to speakers. I switched to Analogue RCA input and connected my turntable and played a record with the same result, no output whatsoever. Then I plugged my ethernet cable to my Mytek Brooklyn Bridge and used XLR cable to Hegel input, changed to XLR input, again no sound at all. When streaming from Roon when I press Next or Previous on a Hegel remote it does skip or go back. So network communication works as expected, except that output does not deliver sound to speakers.

Any suggestions? Did anyone experienced anything similar?

Any help is welcome

Are 100% sure you didn’t inadvertently change the attenuation ? This happened to me on a Hegel H190; There was no output, similar situation. It turned out to the that the volume was essentially scaled to zero.

You have to look in the manual and figure out how to reset it to factory default.

are the speakers OK? Can you measure the signal the goes to the speakers?

Thank you all for your suggestions.

Jason's path forward is the one I'd prefer to leave as the last (though most likely proper one). 

Dpac, yes I have done factory reset.

Grislybutter, I have not measured signal to the speakers, but I have connected my ARC REF 75 and the work just fine.

So far all the paths lead to something not being right with output board of Hegel.

Try shutting off and unplugging for a moment to possibly reset .

if not working after that just try running  and using the built in dac make sure connections are in good , one thing at a time.

Prior to the firmware update did the unit work as expected /pass a signal to the speakers?

When you rotate the volume does the front display have the word “damped” ?
