Why does my Denon AVR-1603 keep shutting off?

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.

If your tv is putting out mono you will only get the center and sub speakers. This can be because the tv is only mono, or the output is set to mono in a menu of the tv. If you have cable or sat run the digital audio out to you receiver; it usually sound better that way anyhow. Set your receiver to Dolby mode for best sound.

You can try resetting the unit, it is a procedure that can make things start working again. Be aware that it will put all settings back to factory defaults, and you will need to go thru and set everything back up again. If it does not work, then you most likely have a component failure that will require serious electronic troubleshooting and this would be best done by a professional.

Here is the reset procedure.

1. Turn power off with the main power switch on the front display, this should make the red led go out. There are 2 power switches on these Denon's. One is a bigger switch and is used most often, the other is a small mechanical switch that is normally left turned on at all times.

2. Hold down the "Direct" and "Pure Direct" buttons together (both at the same time) and while holding them down you turn the power back on again with that little power switch you just turned off.

You should see all the lights in the display light up and then it will turn on to the default setting which, if my memory is right, will be the tuner at it's lowest setting.

Then go thru and reset everything back the way you like it and need it. Make sure that all the video inputs are properly set for each function so you are not trying to get a composite signal out of a function that may be set for S-video or something like that.

Hope this is some help for you.

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.

You need to get the manual and do some reading first. I couldn't find the AVR-1804 but the AVR-1803 is avaiable. It should be close enough to get you through connection and setup.
