No input or output

I bought my KPA Rack only last week and have been using it for only about 5 days and now suddenly there is no input or output whatsoever.

I have looked through all the troubleshooting pages and forum but can't seem to find a solution.
I have done a system reset, reinstalled the latest firmware, checked leads, guitar, output volumes, input settings, midi etc. etc. etc. but no luck.
I unplugged the power lead waited for an hour plugged in and restarted and the tuner leds came on for about a second or two then went off again and it's been dead ever since. I also turned on a profile that I knew had some hum, turned off the noise gate and there wasn't even any hum at the output.

Even though it really is the best sounding guitar device I have ever heard and played, i'm now getting a bit worried about reliability as I haven't even moved it or racked it up yet let alone rehearsed or gigged it. And reading so many issues on the forum about loss of sound worries me.

It looks like it's going to have to be returned for repair or exchange.

I emailed Kemper support yesterday but have not had a reply as yet, does anyone know what the typical response time is for support?

I'm in the UK so time zone not an issue.

Yes I did.

Thanks for the advice but I have checked my spam folder and there is nothing there. I think I will try sending the form again.

I have just sent the form again and this time i got an automated reply so hopefully something will happen this time.
