Re: Wont stay on.
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.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Technician (only for users in the US for now) and get all the help you need. Goodluck!

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.
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.
