Harman Kardon is saying "PROTECT"

[PENG]

However if the PROTECT message remains then the processor is being told of an internal issue.

If that was in fact the case then I agree with you but we couldn't be sure if he meant the message remained even after he disconnected the speaker wires and went through the reset (power on/off according to you) cycle.

The fact it, the guy is enjoying his system since with no further problem so I really doubt there was any internal issue.

As long as everything is now functioning..
No harm no foul.
The protection circuit is very sensitive and any small wire strand on any channel either @ the loudspeaker or AVR rear panel can trigger it.
Case closed..

Just my $0.00...

protect

happend to me 1 time when i'm setting up and connecting my speakers to my hk avr225. I reckon it happens when there's a ground between the connections of your speakers hope it helps
