Hi Andrey,

please let the Jumper in the new position. I got these Instructions from my local support and service distributor. He had some GLDs in past with the same problem you had described.
Only the two things (Battery replacement and set Jumper to new position) will fix this Issue.

I had done this procedure about one month ago and my GLD-80 works perfectly. I think the boot time is the same as before.

Hi,

great to hear that your GLD-80 is operational again !

Yes, you have to leave the ALWON Jumper in the new position permanently.
I got these Instructions from the support Team of my Local distributor. They had the same problem on about 4 GLDs in past. They doesn´t know exactly what the Jumper do, but Allen & Heath know about this Problem on GLD Series.

Its not really necessary to open the big bottom plate to fix the back panel to the console again, but it was easier for me to get the power supply over the circuit board with no cables damage. There is much more space to put all cables in its right position.

Hi,

sorry that i had forgotten to write about the best way to open up the console to replace them.

I got Informations about that issue and to fix them from my local distribution office.

The best way to get to the mainboard is to remove the back panel (Where your XLR and others Connectors are located) and put them onto the big bottom plate. No Cables are necessary to remove and thats the easiest way to get to replace the battery. The mainboard is directly located behind the touchscreen.

Step by Step Instructions:
1. Push all Faders fully in its Up position
2. Remove 5 Screws (Torx T8) from Back Panel on Surface Top behind the Touch and Channel Encoders.
3. Turn the mixer with its Surface down on a soft cover to protect encoders and faders with the direction of the back Panel towards to you.
4. Remove 4 Screws (Torx T8) (two on each side) of the Back Panel.
5. Remove all Screws (Torx T20) on the small bottom plate of the Back Panel (its not necessary and helpfull dont remove the big bottom plate for opening the console)!
6. After removal all screws, pull the Back Panel carefully towards to you and store them onto the big bottom plate. Important that the mixer is in an horizontal and less angled position. No Cables had to remove !!!
7. Replace the CR2032 CMOS Battery and put the ALWON Jumper to the next Position (See Picture attached).
8. Re Insert the Back Panel and be careful don´t damage any cable espacially the cables from the Power Supply. Best way is to put the Back Panel onto the device, after this remove the big bottom plate (all Torx T20 Screws).
Thats easier to push all the cables to its best position and don´t damage them. Especially the cables from the Power Supply.
9. Insert all Screws from the Back Panel small bottom plate first, than they from the big bottom plate.
10. Insert the screws from the Back Panel (Torx T8), then turn the Mixer with its Surface UP and insert the 5 Screws behind the Touch and Encoders.

After you had finished this procedure. Your mixer will reboot after some seconds. The first boot will take a bit more time.

Sorry about my bad english.

See the pictures attached.

Hi,

i´m a Guy from Austria and have the same Problem on my GLD80 Chrome Surface.
Thanks for your great Infos to replace the CMOS Battery and change the ALWON jumper position.

I will try this the next time and hope the surface will boot up.

Can you describe what is the easiest way to get inside the surface to chance the CMOS battery? What screws are the best to remove?

Thanks
