20 Most Recent Denon AVR-1907 Receiver Questions & Answers

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.

I had a similar problem and solved it by simply blowing in the headphone jack (h/p input).

sounds like you might have a bad power transformer.

Sounds like an overload. Make sure it's getting enough air, no shorts, and using speakers with compatible impedance.
If you press and hold down the power button long enough it might reset it...up to 15 seconds I think.

if you are using the ext in then it has to be something wrong with the setup from the pc. The receiver does nothing to the ext in input except amplify it and put it out to the speakers.

Have you connected an FM antenna to your AVR-1907? This is a co-axial socket on the back marked 75 ohm.

Hi, You will need to go into the menu of the AVR to change a few settings. To get into the menu -

1. Make sure you are on an input of the TV that is connected to the COMPONENT VIDEO output of the AVR (I imagine you already have this hooked up)
2. Using the Denon remote that came with the 1907, filp it to the back side and open the door that covers more buttons.
3. Press the System Setup button
4. Go into the AUDIO SETUP
   
5. Make sure the DIGITAL INPUT ASSIGNED is set to none for the audio input you wish to use for the PS3.
6. Going back a menu to VIDEO SETUP, make sure that the COMPONENT VIDEO you are using is assigned to the AUDIO INPUT you are using.

That should fix your problem. If you need more clarification or this did not work feel free to post that on this question. Good Luck

That is called the protection mode, Because of a internal problem with the amp, That is causeing it to over heat, End shut down,

You have a bad "Driver:" or Power transistor in the amp....I usually replace the two power amps and the driver amp/amps at the same time. The pairs are usually matched, and since one interacts with the other, a bad driver will weaken the power amp pair, and vice versa...The overload is the transistor breaking down 9which tends to generate excessive heat), Then the thermistor on the amp pair heatsink senses this condition and shuts the amp down. (NO - replacing the thermistor eill not generally solve this issue, especially since the thermistor qwill survive a temp rise well above what the tranisitor pair will).
