How to troubleshoot an HDMI error that is unable to display video

If your HDMI cable connection fails, your TV may display error messages. These problem warnings commonly prohibit video from being shown on your television.

The faulty case, on the other hand, can arrive at any time and in any number. However, you may quickly remedy the issue by following some basic HDMI troubleshooting methods.

We’ll go over three critical exercises for diagnosing HDMI signal difficulties on your television today. Let’s look at what you should do if you receive an HDMI error notice stating that you cannot display video.

HDMI error that is unable to display video

The first step is to determine whether or not any error messages are present. If you’re having issues with HDMI Error, the following are some of the error signs to check for.

  • Television no longer supports HDCP video over a high-speed connection.
  • Your TV is unable to display video services through HDMI (specifically, H1001). In addition, the HDCP link integrity evaluation is wrong. (H1005)
  • You will frequently receive a “No Signal” message.

These are some of the most prevalent signs of an HDMI issue, which prevents the video from playing. It is critical to use precise ways to correct the problem.

Solving the HDMI error problem

To do so, first, double-check that each unit’s HDMI cable is firmly connected. Then, in the order stated below, perform the techniques.

Turn off your digital box first.

Step 2: Turn off the television.

Step 3: Take a deep breath and hold it for 10 seconds.

Step 4: Last but not least, turn on the television.

Step 4: Last but not least, turn on the digital box.

Step 5: Check your television’s HDMI cable.

Step 6: Check for the presence of a “High-speed HDMI” port. If not, change the label to “High-speed HDMI.”

Step 7: Switch to a different HDMI cable and see if that helps.

There is a multitude of HDMI cables available on online shops such as amazon. Go to Amazon and look at the product to see which HDMI cable I recommend.

Step 8: See what happens with the other HDMI cords.

Alternative method: If 4K programming is not available, a component cable can be used instead.

What to Do If the HDMI Error Remains Unresolved

If the HDMI problem persists after you’ve performed the instructions in Technique 1, you’ll need to try some other choices. You should now test and implement different inputs on your television. Examine your television to see if it supports HDCP.

How can you tell whether your TV supports HDCP?

1. Examine the packaging of your television.

2. Read the TV’s instruction manual. Examine the video-cable portion of the user manual.

3. Look through the video port documentation to see if HDCP is listed. Your television isn’t HDCP-compliant if you don’t see anything like this.

4. Inquire about your television’s maker in the customer service section. Look at the model number to see if your TV is HDCP-compliant.

You’ll see the following types of HDCP-compatible connections if your television is HDCP-compatible:

  • 4K@60Hz HDMI
  • ARC (Audio Return Channel)
  • HDCP 2.2 (High-Definition Content Protection)

Make sure your HDMI cable is plugged into one of the three available ports. The options include HDMI (4K@60Hz), HDCP 2.2, or ARC.

Choosing the appropriate output from the TV menu.

You can set the correct input for your TV using the TV remote input button.

Depending on the TV maker, the input button may be referred to by a different name. If you notice a TV/Video, Input, or Source button, these are also input buttons.

The possibilities are HDMI, HDMI 1, or HDMI 2.

Note: I can utilize the input button even though I don’t have a remote for my TV.

The possibilities are HDMI, HDMI 1, or HDMI 2.

Note: I can utilize the input button even though I don’t have a remote for my TV.

Cycling through the inputs may also entail pressing the input button. While cycling through the information, hold down each choice for 10 seconds so that your TV can establish a secure connection to the connected appliances. Reset the remote control for the television. If your TV doesn’t have a remote, this TV remote might be worth a look.

all gadgets that do not support HDCP are kept out of the way between the digital box and the TV. (If any of your devices aren’t HDCP compliant, try using a backup audio system on your television.) You might also link your audio receiver to your television with an optical connection. If you’re not sure which optical cable to use, here’s my recommendation.

Check to see if your TV’s firmware is up to date.

Go to the manufacturer’s website to see if your television has the most recent firmware. It’s also an essential step in the troubleshooting procedure.

A Quick Consultation Using HDCP

High-bandwidth HDCP stands for “High-Definition Content Protection.” In actuality, it’s a type of digital copy protection. The HDCP prevents digital content from being copied. To suit your content preservation demands, HDCP 2.2, the latest standard, has been applied. HDCP2.2 was not yet available when 4K TVs were initially offered.

The majority of 4K TVs on the market support the HDCP 2.2 standard. If you want to find out if your television is HDCP 2.2 compatible, you need:

   i. First, check the owner’s manual.

  ii. Visit the television’s help pages.

  iii. Check with your television maker.

Problems with HDMI Consumer Electronics Control (CEC):

CEC is a mechanism that allows HDMI-connected devices to communicate and control one another. Pressing the POWER button on a DVD player, for example, transmits data to your TV, causing it to turn on and switch to the DVD input, allowing you to watch your movie. Switching your TV to the CABLE input, on the other hand, signals your DVD player to stop playing and turn off because you’re done with it. Although this appears to be a helpful feature, things can still go wrong.

Your TV may mysteriously switch off while the DVD is playing if the various devices don’t understand each other, or miscommunication may cause the TV or one of the components to “lock-up” and refuse to respond to the remote control or front panel buttons.

I advise you to go into the menus of all connected devices and turn off the CEC feature if some of the components in your system start acting CRAZY. Of course, the proliferation of trade names for this trait, such as:

  • Link to Aquos (Sharp).
  • Bravia Sync vs. Bravia Link (Sony).
  • HDMI’s NetCommand (Mitsubishi).
  • Simplink is a program that allows you to connect to (LG).

Select “control,” “link,” or “sync” from the menus and turn it off. If this resolves the issue, switch off the functionality.

Frequently asked questions

What Is the Purpose of HDMI Technology?

HDMI is most commonly used to transmit multichannel audio and high-definition video data between two electronic media devices. This transmission is carried out over a single wire. HDMI technology is found in AV receivers, PCs, set-top boxes, and camcorders, among other electronic devices.

Can HDMI cables handle 4K?

Make sure your HDMI cable is High-Speed rated and capable of 3D and 4K internet sharing before buying it. Long wires may struggle to stay functional in certain situations. Long cables have a high electrical resistance, which limits the available bandwidth. You’ll need high-quality cables if you’re using long cables to keep the bandwidth stable.

For connecting high-definition devices, HDMI has become the most extensively used and recognized protocol. It has gained popularity because of its adaptation to new technologies and user-friendliness. It also safeguards digital content with high bandwidth.

What is the HDMI connection, and how does it work?

HDMI cables employ the Transition Minimized Differential Signaling (TMDS) technology to send data between two digital devices. It also ensures that data isn’t tampered with when moving from one device to another. HDMI cables do away with the requirement to transcode data for it to be compatible. Because no conversion takes place, photos and movies seem just as they should, with no degradation in quality.

Is There Anything Else That Can Compete With HDMI?

Display port technology is one of HDMI’s primary competitors. This digital display interface was designed by the Video Electronics Standard Association (VESA). It is in no manner HDMI compatible, and it will not function with any HDMI-enabled equipment. As a result, DisplayPort cables will not operate with HDMI equipment.


When it comes to HDMI issues, the On-Screen Displays and other inputs work fine, but the HDMI inputs don’t. There may be no picture, no sound, or both as a result of this. Occasionally, an error message will appear on the source device, or the TV will display a “no signal” error message. I’ve even seen HDMI issues result in “snow” on the screen and hissing sounds in the audio. Furthermore, HDMI Consumer Electronics Control problems can lead any component to behave erratically.

Finally, you may occasionally experience a failure in the HDMI cable connection, resulting in an error message. A TV error display will appear due to the wrong link, and the TV will not display any video. Fortunately, this post has simple instructions for troubleshooting the situation, so you will have an easier time resolving it.
