Qu-24 all the LEDs are lit

Booted my Qu-24 this morning and all the leds are lit. None of the buttons and functions are responding.
Tried to Reset but nothing happen.

Looks like a Christmas light show!

Have you tried connecting to it with the QU Pad app.

Does the screen ever show anything.

Maybe try a force firmware update/reload.

It looks like it’s a hardware issue though.

Thanks Mike. I will try the options you gave me and I let you know…

To do a forced firmware update you hold down the USB and High Pass filter
buttons while powering on.
Of course you need a Qu formatted USB stick with the latest firmware on it already
in the QU Drive USB jack before you power it on.

If by chance the app operates fine you could try it from the set up menu.

The firmware update is a long shot though.

The problem is that i can´t format a USB key in the Qu-24 because the screen doesn´t show anything. All the leds are lit but nothing responds.
Is there a way to format a USB Key without using the QU24?

As far as I know you need to use the mixer to format the USB stick.
Any QU mixer will work if know of another you can use.

Did you try connecting to the mixer with the APP?

I’m going to say it’s a slim chance that a firmware reload will take
care of the problem, but if you can do it it’s worth trying.

I tried connecting the mixer with the App but it doesn´t respond…
I think i will go to an authorized Allen_heath dealer…

I kind of thought that’s what was going to need to be done.

My couple suggestions were that last desperate things to try.

Thank you Mike C for your help and your attempts to solve my problem. I really appreciate man.

Hey, our QU24 at church had the same thing yesterday. We thought it might have been an ellectrical problema, but an eletrician went there today and found nothing. Has anyone figured out why this is happening?

Hello Flavio,

I had to bring my Q-24 to an authorized dealer here in Mexico. They told me they have to change the entire mother board and wanted to charge 1000 dollars for it.
I found another option for half the price, an engineer who told me that the mother board CAN be fixed. So for now we are waiting the original parts to be replaced from China.
I hope it will work.
Al least he managed to turn it on again without all the leds lit.
But it doesn´t complete the booting.
I attached the video the tech sent me

Had the same thing happen to client this past weekend. Summited a request for a ticket or a solution from Allen and Heath. It just seems odd that know one from Allen and Heath has replied to this with a solution. I tried the reset and forced firmware upgrade but only able to format USB through PC. Tried the FAT32 and exFAT with no success.

I’m sorry to hear that. Yes Allen & Heath never answered my mail about this issue. I had it fixed for 500 US. That hurts! According to the guy who fixed it the problem probably came as a thunderstorm occurred and my ethernet cable was connected to the mixer. The electrical discharge probably came from there. So always disconnect this cable when you dont use the Q24 App (which doesn’t work anymore for me).

Why doesn’t the app work for you, are you not able to connect to the mixer?
Is the ethernet jack not working, what version of the app are you using?
Make sure you have the network cable plugged into the ethernet jack and not the S link connection.

Look in the ethernet jack and check for bent connectors.

Sorry my (super late ) response.
I haven’t been able to connect to the Qu-24 with my ipad.
I assume the ethernet Port and Jack are working because the little yellow light is flashing. I’m plugged into the Network ethernet Port.
My Firmware is V.1.97 and the Qu-Pad is V.1.95
I have DHCP enabled in the SetUp/Control/ Network

Hi - I am checking to see if you have more information as to what you did to repair your QU-24. Our church just got hit by lightning this past weekend and our QU-24 lit up like your board. You mentioned a video you posted…I didn’t see anything or maybe it’s been so long ago that it was taken down? If you could provide any input - like the part/board you needed replaced or anything else we would appreciate it. Thanks so much.

Here’s your post I’m referring to:

Hello @Guiguix and @PS,
I’m sorry to hear that you didn’t hear back from the Support team at A&H.
We reply and follow up on all enquiries, if yours was not replied then it is likely that it did not get to us, unfortunately. Please make sure that messages are sent to: Support@allen-heath.com

If we did get back to you but re-direct you to one of our distributors for technical service, then our distributors shall take over the enquiry in which case follow up will be directly through them.

Please note that we don’t officially support service done through unauthorized centres, nor do we recommend component level repairs, as neither of these procedures would guarantee your product being fixed and returned to you in operational conditions to our company standards.

If you’re having hardware issues with your Network connection, it might be worth looking at the CPU board once more. Since it suffered some damaged and as it was not replaced entirely, it is not guaranteed that other areas or components were not damaged as well.

Thank you,
Rafael
