worth reading first as it may be similar.
then, assuming your batteries are well-charged, I'd do the following first:
Find your AC to DC converter/charger. Probably under the lowest drawer of the cabinet for the stove top. Way in the back mounted to the floor. (that's where it is on my '07 38T.)
Unplug it from the 110VAC outlet and check the status of the EMS panel.
If it appears to be working fine, it might be the same problem I and others have had w/ the converter.
I have heard also of the displays going bad, and loose connections.
good luck
