Display won't wake from sleep on mouse click or keyboard action

Hi Mac Mini Server is set up with a Thunderbolt Display, it is connected as a server but also I use it as a computer generally running Parallels in order that i can run some PC only software on it. It has worked fine for 12 months with the screen going to sleep after 15 minutes but since it also works as a server the macmini itself is set to Never shut down. Normally one click of the mouse and the screen lights up and i can work away. Now the click on the mouse or a tap on any key on the keyboard fails to light up the screen, despite the fact that the Mac Mini is continuing to work as a server.

Any ideas woudl be gratefully received..

Mac mini Server (Mid 2011), OS X Server, Thunderbolt Display

It also seems to be related to later OSX versions, like 10.8.x & 10.9.x

The 2012 macs (and later apparently) (also later OSX versions on earlier Macs can do it also), not waking normally from sleep after hours being in sleep. (noted here ...

The sleepimage file still reappears even if never slept. Delete it (hibernate off, etc) - within minutes its back.
