Steve, Yes that does sound suspiciously like a missed or bad solder connection. Take the front panel apart and examine everything reflow the soldering if you can't locate it by inspection. Don't forget about the connectors - and the 'other side' of the connectors on the RF board as well - check the control board connectors while you are investigating too - these Front Panel signals mainly go to the Control Board by way of the RF Board.
