Your TV is not getting any signal from your Denon receiver, and you just want to know what’s wrong.

To fix your Denon receiver’s HDMI output, you need to set your TV to the correct input source. It could also be a faulty HDMI port, so try plugging your cable into another port. You can also activate your Denon’s HDMI ports by turning them on in your receiver’s settings.

Why Denon Receiver HDMI Output Not Working

There are a few points of failure when the HDMI output of your Denon receiver stops working.

You have to consider the ports, cables, settings, and even your devices. It could be a simple disconnection, or your receiver is not set up properly.

Here are the issues that have happened to your entertainment system that can cause this:

1. Setting The Wrong Input

Your TV has a few HDMI ports that you can connect to your receiver. You’ll need to select one as the input source. If you choose the wrong one, you will get a ‘No Signal’ notification.

2. Inactivated Video Ports

Some Denon receivers come with two HDMI outputs. These should work, but it could be set that only one is activated. You’re likely plugging into the one that’s not working, so you’ll need to switch it on.

3. Faulty HDMI Cable

HDMI cables can also malfunction. If there’s a break, the signal will not be able to propagate and causing this error.

4. Hardware Malfunction

Your Denon receiver’s HDMI module can break down and not send signals to your TV. If this is the case, it will need repair or replacement.

These are the problems that have an impact on your Denon’s HDMI output.

Now that you have a better understanding, we can proceed to the troubleshooting steps so you can start using your receiver once again!

How to Fix Output HDMI Port Not Working on Denon Receiver

Before you start working on fixing your Denon receiver’s HDMI issue, it’s important that you restart it and your TV.

The problem can be temporary, and a reboot will restore any minor issues. It also has the potential to save you a lot of time if it works.

However, if it doesn’t work, you can proceed to more in-depth steps to resolve the error.

Solution #1: Set Your TV to the Correct Input Source

One of the first things you need to check every time you experience a ‘No Signal’ notification is to check your TV’s input source.

Your TV may still be set to a source like your Xbox or Playstation that’s turned off. Make sure that you check it and change it to your Denon to see if it works.

Here’s how to set the input source on your TV:

1. Press the Input button on your TV’s remote.
2. Wait for the Input screen to show up on the display.
3. Select the source that your receiver is connected to.
4. Press the Enter button to confirm.

Note: There is also a physical Input button on your TV. You can press that if you don’t have the remote with you.

Solution #2: Plug Your Receiver into a Different HDMI Port on Your TV

There may be something wrong with the HDMI port that your Denon receiver is connected to.

It could be dirt or a hardware issue, but the fastest way to check this would be to plug it into a different port on your TV.

Here’s how to check your TV’s HDMI ports:

1. Unplug the HDMI cable linking your receiver and TV.
2. Find an open HDMI port on your TV.
3. Plug your receiver into the available port.
4. Set the input source of your TV to the new port.
5. Check if your TV receives a signal.

Note: You can also test this by plugging a different device into the same port as your receiver and checking if it works.

Solution #3: Set Your Video Out Settings Correctly

There are Denon receivers that support multiple HDMI outputs so that you can connect more than one screen at a time.

These should work by default. However, there’s a particular configuration that can disable this.

In your case, it could have been disabled, leaving the HDMI ports not usable. You can easily correct this by going into your receiver’s menu and changing the settings.

Here’s how to set the Video Out settings on your Denon receiver:

1. Press the Setup button on your Denon remote.
2. Navigate using the cursor keys to the Video menu.
3. Select HDMI Setup.
4. Click on Video Out.
5. Set it to Auto (Dual).

Note: This makes sure that your Denon will activate all the HDMI output ports it has and make it available for use.

Solution #4: Replace Your HDMI Cables

If none of these steps work, you can be certain that the issue will be with your HDMI cables. The first thing you need to do is look for signs of damage.

If you can see no signs of physical damage, the connectors can have faulty contacts that will not send the signals properly. If this is the case, you will need to replace your HDMI cables.

Here’s how to check your HDMI cables for damage:

1. Flickering dots on your screen before the ‘No Signal’ alert.
2. Check the cable for fraying and breakage.
3. Check the connectors for damage.
4. Use an HDMI cable from a different device.
5. Get new ones that are at least HDMI 2.0.

Tip: Invest in spare HDMI cables to make troubleshooting easier and quicker. Use HDMI 2.1 for best results.

Solution #5: Reset Your Denon Receiver to Factory Settings

Glitches can also occur on your equipment. Usually, a simple reboot can clear up your device’s circuits and take care of it. However, there are instances where it’s so embedded that it’s difficult to remove.

If this is your case, your option would be to reset your Denon receiver back to factory settings.

This will clear all the settings and information saved on it. It will also delete the corrupted system files that are causing the issue.

Here’s how to reset your Denon receiver:

1. Turn off your receiver by pressing the Power button.
2. Press the Power button again.
3. Also, press the Tuner CH+ and CH- buttons.
4. For some models, it’s the Info and Back buttons.
5. Wait for ‘Initialized’ notification

Pro Tip: There are times when a single reset won’t do the trick. You can do it up to 5 times or until the issue is resolved.

Resetting your Denon receiver is your last resort. If it still does not resolve the issue, contact Denon support for more assistance.

You’re likely dealing with a hardware fault that will need repair or replacement.
