Qu 16 does not boot

Qu Qu Troubleshooting
1

Hello,

hope you can help me. Yesterday, my Qu16 worked as well as always. But today, i am not able to start the mixer.
After pushing the start button, the only reaction is a running light on the Pan controller. The display does not boot up and of cause no other leds are flashing.

Before i shut down the mixer yesterday, i made some changes on the network configuration and i also connected a Q- drive before i try to start the console.

So pleas can you help me to find out whats going on?

Thank you so much,
Aloysius

Check the fuse. Try a hard reset (see manual).

Hi Aloysius,

This symptom usually means the mixer has can’t find the firmware and therefore can’t boot.

Please start a ticket at support.allen-heath.com and we can try a forced firmware install.

Thanks!

Describe the “forced firmware update” maybe handy to know if I ever
need to do that in the future.

Ok, here is the description of the support:

Please try a forced firmware reinstall.

This is done by loading the firmware onto a formatted USB drive, outside of any folders including the AHQU folder.

You then insert the drive into the USB A Qu-Drive port when the mixer is powered off.

Press and hold the USB and HPF In keys whilst powering on the unit. It will then show this same behaviour and, if it loads the firmware successfully, it should eventually boot.

If this doesn’t solve the problem, it is likely a hardware issue.

If the QU16 is functioning correctly when controlled with the iPad the issue may be just with the display itself.
You should be able to do start a firmware update with the iPad. You will need the firmware loaded on a USB stick plugged into the mixer.

chirlo, I would try a hard reset. First do a full show save to usb drive.

To hard reset the Qu mixer - Press and hold the
touch screen Reset and Setup keys together and then
power up the mixer. Keep the keys pressed for at least
5 seconds while the mixer boots. Release the keys.

Hello,
Where is the USB key ?
Many Thanks ;-).

Press and hold the USB and HPF In keys whilst powering on the unit. It will then show this same behaviour and, if it loads the firmware successfully, it should eventually boot.
