Turned on my G68 tonight and… nothing… well, the blue led behind the buttons flashed for a second then died. Tried a different power cable, tried unplugging etc. Just a teasing second of blue… searched but could not find any similar issues… but could have missed something.

It’s connected to DSP5000s and DSP33s. Fed from a UHD722.

Any ideas for things to try?

Thanks.
