I have a Harman Kardon AVR 235 Receiver that go's into Protect
Mode. This is the first time it has happened, yesterday I thought that I would connect my Hafler 4000 to the pre-amp out Left and Right and see if the sound was better, and the Harman Kardon wet into protect when the Hafler transient powerup came on.
Is there anything that I can do, I have a birthday party coming up in 15 days, and the last time I gave it to Harman Kardon they kept it for 3 months. I'm in France and there are no repair shops locally at all.
I checked all of the contacts speakers/receiver, and they were all ok.
I really hope that you have a solution
Re: I have a Harman Kardon AVR 235 Receiver that go's...
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.

Ensure that your speakers are connected to the terminals that you have your speaker selector switch turned to. Then check that you have your device, whether it be a CD or DVD player, or turntable, plugged into the correct input and that you also have the correct input selected on the receiver.
It will only display via component. Your HDMI firmware is either 1.1 or 1.2 and has HDCP issues (High Definition Copyright Protection) it's a firmware problem that has been fixed on all new receivers, not just a HK issue, all receivers! the new version 1.3a and 1.3b have fixed the issue. Unfortunately you cannot update the firmware on the receiver. Hope this explains it for you, sorry! Lot's of angry people out there!!! myself included.
The only way you can fix this is you have the proper tools and have very good soldering skills. If so, I will post more instructions on how to fix this.
It has a blown channel, it can not be fixed without some good troubleshooting skills. The protect mode is so you don't cause more damage to it. If you continue to turn it on, you may cause more damage.
Your best bet is to take it in to get repaired at a service center.
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
