I have 2 Rad Rovers.  One is not powering up unless I disconnect/reconnect the Display connector to the power pack (metal threaded rings to lock).  When I do this, it powers up, but next time, same thing.  It is as if the disconnect, resets something.  Very annoying.  I can replace something, but I need to know what to order.
Any help is greatly appreciated.
Cheers,
Will
