Genelec 1238a red light after turning on

First, the system has been up and running for a couple of weeks. Two 1238a, GML network, connected both analog XLR and AES/EBU. The day before yesterday, they have been sucessfully in operation controlled by GML both digital and analog, yesterday with the computer offline (and thus GML offline), they were in use with there stored settings with source coming via the analog route. No problems at all, then both monitors had been turned off.

There have been no changes until today, when I turned both monitors on. Neither GML nor any source were on at this time. Left monitor went red. I wondered, opened the Mac (and GML interface became active). GML displayed one speaker online (the right one) and played on one speaker when starting playing from iTunes after turning on the AES-USB-link.

This is were I started troubleshooting and I will describe the steps:

1. Power off the speakers: The left speaker can not be powered off via the button. Needed to pull the plug.

2. Putting the plug back in: the button normally flashes green for a couple of times, then remains stable green. Not the left monitor: the button is green as soon as there is power. And the front is red. I have the feeling, that red is not as strong as the flashing red light I know when the AES-USB link is still offline.
(very strange: after some experiments I also got a yellow light twice, however, with GML off. The behavior on putting the plug back in that the power button is instantly green remains the same. Update: tried again this morning, light is red)

3. Disconnected GML network, tried to boot the stored settings, does not work, behavior as in 2.

4. Directly connect just the left monitor to GML with all other cables disconnected. It is not recognized.

5. Strangely: connect as well the right monitor via the left monitor, then the right monitor is recognized, therefore something works…. . Again interesting: the yellow of the working right monitor appears a bit brighter than the yellow (in another experiment it was red) on the left monitor.

6. No connections at all, light red, button instantly green and button does not work to turn the monitor off.


I will contact my local dealer tomorrow, still, I would be glad for any recommendations! Is there some boot or reset sequence? (the lacking of the blinking green light seems to me as if some boot sequence fails…).
