GLD80 white screen, no lights

[andrewahmadParticipant]

Thank you so much for writing up these instructions! I replaced the CMOS battery, moved the ALWON jumper and my GLD-80 is operational again! Should I leave the ALWON jumper in the new position permanently? What does that jumper do?

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.

This ALWON jumper sets the mode to always on, without the POWER button. as soon as voltage appears on the motherboard connector, the system automatically starts.

Hi. Today, when the GLD-112 is turned on, I see the following picture, the display is white, there is no illumination of the control elements. The system does not boot, tell me you had similar symptoms?

Hi.Thank you so much for the information on this issue.After I replaced the element and rearranged the jumper, the remote loaded in 10 seconds. I tried to return the jumper to its original position, then the problem returned. After the new position of the jumper, the system does not load as fast as before, you have to wait 5 seconds, after which the system starts, it used to be faster. Please respond, who did the same procedure, how does your remote control feel after these actions? Does it fail you more?I don’t want to get into a situation where it doesn’t start before the concert.

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.

I had the same problem on a GLD112, noticed the battery, pulled it and it was at less than 10% the labelled voltage, so I replaced it, and that wasn’t sufficient to fix it. I moved the jumper as described here, and that did allow it to boot. It had some old settings saved, but I didn’t get into many details with the church I got it from, and I’m handing it back over to them tomorrow.

It seems to be running Linux. There are PS2 connections on the motherboard, so I wonder if there’s anything to be gained from trying to get to a terminal.

I appreciate the explanation about ALWON, but it still doesn’t make sense to me. The mixer is plugged in, but it’s not on, and doesn’t come on until I hit the external switch.

How was it coming on before the jumper was set? Was there something else turning it on? Is that something else now broken?
