At this stage the 68v is dropping down to 6v when connected to the DMD Display. When the power connector is removed from the DMD display 68v returns to circuit board connector.


So, on the pins on the DMD display, pin 8 (68v) and pin 6 (5v), is reading continuity on my MM. 
Without the schematics, can someone clarify if this is correct with their WPC board or is this the frustrating short I’ve been looking for?
