Question about Denon AVR-1603 Receiver

Receiver goes into protect mode when hitting certain volume level

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.

I'd treat this symptom as "DISPLAY not lit and power indicator is flashing rapidly." under Troubleshooting on Page 60.


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

Two front channels don't work, speakers and wires


First of all please check the mode in which you are operating. Use the tester to see if there is tone on the speakers. Use a good DTS source and swtich over to 5.1 to check for requrired levels. If there is no sound yet, please open the cover and check for the connections to the front channels, check if the relay is clicking. You will have to look into the output mosfets for damage. for this the main board has to be accessed. If you think that you are not able to go deeper into find out the nearest Denon service centre. many such centres do not accept a set if tampered and so you need to be careful not to make it more costly. Hope my advice helps. Good day

Hit some buttons, now i can get 7 channel output.


Get into System Setup and run through the Speaker Configuration routine. My bet is it thinks you don't have Surround Back speakers.

Protect is ON


Either there is a bad capacitor in the protection unit or you can find the wire that goes from volume control to protection unit and unplug it.
You can also try turning the volume all the way off before turning on, then slowly turn up from there

Vinyl on Turntable sounds thin and trebley through Denon AVR-1603


You will need an adapter amp which converts the tiny tiny signal from a magnetic phono cartridge up to the line level that you need to feed into your AUX input jacks. They cost about $20 to $30 dollars and can be found at Radio Shack. Unless of course you have a phono input jack on the back of your Denon unit. Good luck.

Denon AVR 1603 goes to stand by mode


It has a blown channel, unless you are good at repairing them I suggest an authorized Denon service center. This Denon not only needs the shorted output transistors replaced, but a few resistors, a couple of driver transistors and a capacitor on the preamp board as well. alot of parts to be replaced. I have repaired about a hundred of these over the last few years and my shop charges about $200 for this repair, other shops should be about the same.

Denon AVR-810 going into PROTECTION mode


It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck
