Hi Harry, No, it's single cables all around, and I tried swapping cables and removing them entirely, in case of a short - no luck. Also, there's no reason a cable would go bad "all of a sudden" ... the machine was working fine one minute, then didn't work the next minute after an attempted reboot. Thanks. --- Amir On Thu, 23 Feb 2012, Harry A.
