I just got a LC-46D92U and am having the same problem, I tried sending the RSPW0001{CR} code but still can't get a response from a POWR0001{CR} so I assume that I need the firmware. Please send me a copy if you can.
Thanks,
Mike
P.S. Is there a way to get the unit to display what firmware is loaded currently?
