Justlisten do you have an ohmmeter or access to one? Or even a rudimentary automotive test light? You simply need to check for continuity between component's chassis ground & the IEC's third pin to determine if that connection is made.
Data is not carried on the ground leg, but sometimes logic ground depends upon that connection. I can help you out with a couple of other suggestions to check; just email me offthread w/ phone# contact if you want to talk about that, because it's not nearly so easily written as it is spoken.
