How To Fix The Denon Receiver Turns Off and Blinks Red Issue

Below, we will explain what exactly causes this problem and what you can do to fix it. If you are not all that experienced troubleshooting issues such as these, don’t worry. We will do our best to guide you through it step by step.

What Does The Red Blinking Light Mean?

If you have this issue, you’re probably wondering what does the red blinking light signal mean. The red light is actually something that’s called a Protection Light. It starts blinking when the thermal monitors and current sensors detect an abnormal operating environment.

Sometimes, the problem can be resolved by simply doing a detailed checkup and restarting the receiver. But in some cases, the red blinking light could be signaling that there is a more serious complication that needs fixing. If that’s the case, here are a few methods you can try to eradicate this problem.

  1. Let The Receiver Cool Down

Let The Receiver Cool Down

It’s possible that the red blinking light issue is caused by your receiver overheating. If that’s the case, the integrated circuit should automatically reset after you’ve let it cool down for a couple of minutes. Once the receiver has cooled down, the protection light should be gone, and you will be able to continue using your Denon receiver like you usually would.

  1. Turn Off The Receiver And Check Connections

The culprit behind your issue could also be poor operating environment. For example, low electrical resistance, a faulty speaker, or a short speaker cable can cause the red light to appear. In that case, you will have to turn off your receiver and reset it. Don’t forget to inspect every wire connection to and from the speaker.

Once you’ve done that, turn the receiver back on. If the protection light appears straight away, you will have to redo the testing, but this time, make sure to disconnect the speaker wires on the receiver side.

If the protection light doesn’t pop up this time, it means that there is a problem with the speaker or one of its wires. You can use a system of elimination to determine which wire is the faulty one by connecting them one by one and retesting every time you connect a new wire.

  1. Initialize the Microprocessor

If the previous methods didn’t work for you and the red blinking light issue is still present, then you will have to initialize the microprocessor. What that means is that you will have to reset your device. Check the owner’s manual to find out what steps you need to take to initialize the microprocessor.

Keep in mind that by resetting your device all of your setup configurations that have been stored in the system will be deleted and that you will have to do the whole set up process again.

So, it would be smart to write down your settings layout before you proceed with the reset. This will make the setup process much easier and quicker once the reset is done.

  1. Take Your Receiver to An Authorized Repair Center

If you don’t feel confident to do the reset yourself, or you have already done it but the issue still seems to be present, then it might be time to ask for professional help. You can either call a repairman or take the receiver to an authorized repair center.

They have the tools and the knowledge to figure out what’s wrong with your device and how to fix it, not to mention that it’s much cheaper that replacing the receiver itself. Hopefully, they will have it back in working order in no time.

  1. Had this experience today on my DENON AVR-X1400H. I took the device to The Geek Squad at Best Buy. Nope, I did have protection on the receiver. I purchased the receiver ($600) almost five years ago. Geek Squad rep further stated that even if I did have a protection plan, they would not work on the receiver because at this time…. too hard to locate parts. Really! Nevertheless, I purchased another DENON receiver at AVR-S540BT ($349.00). Salesman asked if I would like to buy a protection plan. I said no. Since the Geek Squad won’t work on them, it’s no need for me to waste money on a protection plan. I will just come and buy a new one like I am doing now. Bummer!

  2. My AVR X 2600H did this fast flash… I have 4 Ohm Polk audio fronts…Go to
    0 Carry out the following settings when using a speaker with an impedance of 4 – 6
    ?/ohms.
    1. Press and hold the main unit’s ZONE2 SOURCE and STATUS at the same
    time for at least 3 seconds.
    “V.Format:” appears on the display.
    2. Press DIMMER on the main unit three times.
    “Sp.Imp.:” appears on the display.
    3. Press TUNER PRESET CH + or TUNER PRESET CH – on the main unit to
    select the impedance.
    8ohms
    (Default):
    Select when the impedance for all of the
    connected speakers is 8 ?/ohms or over.
    6ohms: Select when the impedance for any of the
    connected speakers is 6 ?/ohms.
    4ohms: Select when the impedance for any of the
    connected speakers is 4 ?/ohms.
    4. Press the main unit’s STATUS to complete the setting. This fixed mine

  3. Good day where are struggling to get help if we experience problems, l like the name of brand is powerful. The problems is when you turn the volume up it give problem it turn itself off. And your enjoy the music is hot in the room is really boring. I wonder if is broken I will get a right person to fix it.

  4. My Denon receiver only and just about always does this with audio book disks but not music discs- any clue about that glitch?

  5. It is very late posting but maybe this is usefull for someone.

    I had the same problem of receiver shutting off and red light flashing. My receiver is a Denon AVR-X550BT.

    I checked several times the speakers and connections and everything was fine.

    Finally I discovered that the problem was the signal coming from the sattelite box over HDMI cable. The solution was very simple. I used a HDMI cable with ferrite beads on the endings (https://en.wikipedia.org/wiki/Ferrite_bead). The ferrite beads are filters for high frequency noise. The problem was very frequent on my receiver and simply disapeared after change on the hdmi cable.
