Blank Display on upgrdade to 7.8.1

I've just upgraded to:

Logitech Media Server Version: 7.8.1 - 1414138422 @ Fri Oct 31 03:05:20 CUT 2014 on Windows 7

MY SB Touch players are fine but on the Boom the display when off is now blank even though screensaver when off = Date & Time, standby font = full_n and power off brightness = 3

The display does show the time if I press sleep button.

I just want it show the time when off, any ideas?
