There is an internal reset switch mounted on the transformer board. Open the unit, look at the boards attached to the transformer, the pushbutton is facing up. Measure the voltage on the 2 pins of the switch. If it is a logic low, the switch is partially shorted. Replace the switch or just cut the jumper wire just below thw switch. When this switch fails, it constantly resets the receiver and stops it from powering up. It does not fix a protection mode problem.

HK's must be programmed to output sound. It's probably back in the default mode and you need to go thru the menu for setup of sound output.

I also had this UNLOCK message on my Harman Cardon AVR 130.
The reason for this error was - in a hurry I've plugged the optical input into optical OUT! Double check that your connections in the back are correct and hopefully it fixes your problem.
