Typical case when a reboot to the Media Player is needed, is when the Display is showing old content or an orange bubble. This might indicate that the Media Player is not connected to Valotalive.
You can verify the status from Valotalive in the DISPLAYS tab:
All green displays are online, all red Displays are offline, not connected to the network or to Valotalive service.
How to Reboot the Media Player
Locate the Media Player
Chrome box = A black box attached to the Display with HDMI cable. It is placed near the screen, max couple of meters away from it.
Press down the power button and wait for 15-30 seconds
Press down the power button again.
Wait for couple of minutes more. Your messages should start to flow to the screen.
In case your screen is showing Waiting for content or orange bubble symbol please check that you have assigned content Flows to the screen.
If everything seems to be in order or your screen is showing PIN here, please contact Valotalive Support for further instructions.
