There are no more fuses that will make this work.Turn off power and disconnection the primary side of the power transformer (the big one) check with a ohm meter,it should read all most a short,if it reads nothing you have a defective power transformer. The transformer will be bad if you get no standby light at all,that is if all fuses are good.

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?

This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

I have had my Denon AVR-1907 for about 20 months. About two months ago, it started shutting down and the On/Off button blinks red. Almost all the time it would clear by itself for no reason and then work...

You will have to check with a volt/ohm meter the + and - 15volt regulator ics in the power supply if they are off by more then 3 volts it will shut down as soon as it is turned on,and you still will have a flashing red light. also you may want to check the output transistors for shorts if your regulator ics are good.

Has power but keeps switching to standby

Disconnect all speakers at the receiver and turn it back on, if it stays on post a comment and I will help you troubleshoot further. If it still cuts out, it needs to go to service for repair. Hope this helps.

Denon AVR-1907 blinking red power button

It sounds like you have a bad speaker on the zone 2, or you have the speakers connected improperly.

When you engage the zone 2 a relay clicks and the speakers then become part of the amplifiers circuit.

If the problem was in the amplifier, it would go into protect mode without even having speakers connected to it.

If the speakers all check good, you most likely have the wrong type of speakers, meaning the impeadance is too low, or you have too many speakers connected to it.

On the back of the Denon, you will see right around the speaker output jacks, what ratings the speakers should be. If I remember correctly, it says 6 ohms or more when using only "A" or "B", and it says 12ohms or more for "A" + "B".

If you have two 8 ohm speakers on the same speaker jack you now have a 4 ohm load. That is below the ratings and can cause the amp to shut down (go into protect). Since your amp shuts down right away, I think you have a bad speaker or way too many speakers connected.

I have seen many times when people will connect 2 or 4 speakers to the one of the outputs that are designed for only 1 speakers.

If you are using too many speakers you will need a speaker distribution box. It has a resistor network built into it so the amp never sees a lower impeadance than what it is designed for.
You can connect 4, 6 or 8 speakers to one set of outputs designed for 2 speakers. You do loose a lot of power to the speakers, but it is better than blowing up your amplifier.

If I can be of any further help, let me know.
