Question about Denon AVR-1603 Receiver
My Denon AVR-1603 goes into protect mode when it hits a certain volume level. The volume level really isn't that high. This only happens while set on Dolby Surround. This has only been recently happening.
There is a problem in one of the output channels of the amplifier. That is the only reason it will do this. I work at an authorized Denon service center and have seen this problem several times, but it has never been the same thing that causes it. It has always resulted in extensive troubleshooting to find the problem. One time it was a capacitor in the pre-driver circuit for one of the channels, another time it was a transistor in the same type of circuit. I can not remember all the other causes. But without the proper tools and the knowledge of how to troubleshoot an amplifier circuit you will never figure it out.
Since this is an older model, more than 3 years old, it is no longer under warranty. They get a 2 year warranty from Denon. You can take it to any service center that works on stereo equipment and they should be able to fix it for a reasonable fee. Probable around $125 to $150 depending on their rates. It may seem like a lot, but it is much cheaper than buying a new one.
Since this is really the only option for you, unless you have the tools and knowledge, a FixYa! would be much appreciated and appropriate.
If you would like to troubleshoot it yourself, let me know, I have the service manual in PDF and can email it to you if you like and help you with troubleshooting it. But be aware, it is not an easy job.

and I'd evaluate the speaker load you're presenting to make sure it's effectively higher than 6-0hms per speaker channel.
