We've got a pair of Mediabox 300s, with two Sharp televisions connected to each box via HDMI cables.
If we turn off the power to the displays but leave the Mediaboxes running, when we turn the screens back on the "#2" screen on each of the pairs displays the "Signage presentation will resume momentarily" message until we reboot the mediaboxes, at which point they play the content just fine again. I've swapped the HDMI cables between displays to confirm that this is not related to the cables in any way.
Is there a setting somewhere in the mediabox that we can change / update to remedy this? The screens are clearly getting a valid video signal in order to show the "will resume" graphic....
The stations report they're on version 4.11.29, with airVersion 3.7.0.1860.
