Reply to VCI-100 problem

Hi guys, first of all, sorry for my bad English.

In last event i accidentally dropped my VCI-100, now i have problem, when i turn up both volume sliders, vci turns off.

Right volume slider doesn't work.
I'll post video, then you will understand

Maybe there are some way how to fix it, cause i have one week left till next gig.

Thanks
