Express wired RFU... stuck in ".......waiting for communication". As stated , it worked great for hours, disconnected it for the show, plugged it back in afterwards to do change-over and now its stuck. I metered the wires between the connector and circuit board, that seems ok. Led is blinking on circuit board. And I have re-seated the chips. This was plugged directly into the console for testing... Any other ideas... I was temped to lop off the connector and resolder, but thought I would post to the forums first. Thanks -Bob
