The display is blank and the green led on the control panel is lit.

If this issue occurs, check connectors J210 on the DC Controller and J8112 on the Main Controller. If one of the connectors is not seated properly there will only be 3 volts output from the Power Supply.
================================

The machine is powered on but the display remains dark. Nothing other than the Green Power LED comes on.
Verified that 3.3v was present on J8125 pin 3 of the Main Controller.

The solution in this case was to replace the Main Controller.
