Amp protection switches off
SOURCE: Harman Kardon AVR35
check that your speaker wires are connected properly, and none of the wires are touching. if this dosent work hold the sur mode and tune mode at the same time with the unit off(in stand by mode) and this will reset the receiver
SOURCE: I have a Harman Kardon AVR 235 Receiver that go's into Protect
To avoid making the avr go into protect mode when you power up your Hafler 4000 that is connected in the avr's pre-out, you must power up the set up in the correct sequence.
1. Turn off your avr
2. Connect Hafler 4000 to the avr's pre-out it it is not yet connected
3. Turn on your Hafler 4000. The avr will not go into protect mode becasue of the transients from the Hafler because it is still not powered on.
4. Turn on you avr. There should be no more transients from the Hafler at this stage unless it is not functioning correctly, so the avr shouldno longer go into protect mode.

I used the live chat and the problem was resolved.
Usually the problem are strands of speaker wires which cause shorting and protection shuts off the receiver in order to prevent damage. There was one speaker that I repositioned recently which was causing shorting. I twisted the wires and tightened them in place and my receiver has been working w/o a glitch. I was lucky that I did not have to check all the wire strands on the receiver and all the speakers.
Problem solved and I learned valuable lesson.
SOURCE: can I conect harman Kardon avr 230 to apple tv
Yes, although it (AVR) does not support HDMI only component video.
Connect the audio to the receiver and the video directly to the TV if you have inadequate video inputs, or want to take advantage of the HDMI.
