Well I do not know how is on your model, usually it is all on the same mainboard. if its transistors you change the transistors , or there may be a thermic swithch that turn system off.
You should also consider that may be a fault on some of the control chipset.
A problem of this kind won't be an easy DIY unless you have a good background.
I do not have diagrams or schematics for your model, If I find some, I will send them tomorrow.


Leave your denon unplugged overnight, place it away from other devices, until you fix the problem.

Give me your location if you also need directions for local service support.

I will post back tomorrow

How do i assign a record player to ''aux ''input terminals of a denon avr 1507 amplifier


Depends on the record player (turntable). If it's old-school it will need a PHONO preamplifier to raise the level and frequency-balance the output according to the RIAA curve. Otherwise it will be uselessly low in volume and tinny sounding.

Phono preamps are available at a lot of electronics stores online. Google it. If you have an old school receiver with a PHONO function you could use IT for the TT and send its output to the Denon.

If it's a newer TT it may have its own internal (selectable) preamp. Then it would drive any standard Line Level audio input.

Play phono - vinyl records


You need to purchase a phono preamp (about $20) and then the output of the preamp can be connected to any line level input on the receiver (tape, CD, DVD etc.)

Shuts off after only a couple of sec.


Your reviever is "clipping". You need electronics service from a professional repair shop.

If you are savy in the world of electronics... Most likely you have a bad cap or preamp circuits that are overdriving the amp supply.

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 receiver follow up


A sound spike should not heat up the unit enough to shut it down. There is another problem. What is the time frame for the shutdown? Is it only after the unit has been running for a while?
