Our church uses a QU-16 chrome edition. About a week ago, it suddenly stopped working. When we power on the unit, it powers on, but the screen is blank and every LED light on the unit (channels, EQ, pan, L&R, Mix, FX etc) comes on. Buttons and faders don’t do anything. Here are some of the troubleshooting steps we have taken but nothing worked:
1) Tried turning it off an on again multiple times
2) Unplugged from current outlet and plugged it into other outlets
3) Changed the power cable
4) Tried resetting it by pressing Reset and Set Up while powering on the unit
5) Tried to “force install” the firmware based on suggestions on other posts on this forum by inserting a formatted USB drive and booting up the unit while pressing PFL and USB buttons.
6) Changed the fuse with another one with the same rating
None of the steps above did anything. Any help would be much appreciated!
Thank you.
