I stripped the Netduino down to just the Netduino and the LLC to try to get the screen to activate via the onboard button but not much luck. When the code loaded and the Netduino started up the first time, the screen came down without any interaction. Some times I could hear the relays ticking over but it it wasn't doing anything to the screen...
I did have a look at the components in the screen module and managed to identify the relays being used 833h-1a-c and found the data sheet for them
