HDMI cables are used for high definition content. If this is the case, then why are you seeing intermittent picture and experiencing no sound? These are likely signs of a bad HDMI cable. 

Before deciding whether or not to discard your HDMI cable, our audio team will help you identify if it can be repaired again, and to check other factors that contributed to its damage. 

Do HDMI Cables Go Bad?

Similar to other cables, an HDMI cable can go bad. How you store your cable, such as coiling or bending it can damage the HDMI[1] over time. Maybe you unplug and plug in the HDMI cable too roughly, because that can also damage the inputs. Even heavy use of the cables and devices it’s connected to can cause the breakdown of the cable.

Purpose and Importance of an HDMI Cable

You may be wondering what the big deal is with HDMI. It’s the standard for quality signal relays if you want high quality audio and visuals. HDMI, or High Definition Multimedia Interface, comes in many different types that can either be a mini HDMI or a micro HDMI, each molded for certain products and designed to handle heavy loads.

We have evolved from the basic HDMI cable to new HDMI options such as the 2.1. The 2.1 HDMI can handle 10K video and audio quality, and improve upon the 4K and 8K content.

What’s also amazing about HDMI is it’s a one cable stop for audio video without the need for separate cables. This was all the rage when HDMI was first introduced, plus the handshake information. Handshake information includes things such as capabilities of devices and copy protection data.

Signs of a Bad HDMI Cable

How do you know if your HDMI cable has gone bad? You might experience an issue with the picture. The images could simply be fuzzy, or you may see no picture at all.

Another sign of bad HDMI cables could be weird color. Experiencing muffled or no sound is also a common sign of a bad HDMI wire. 

In general, if you are experiencing any quality issues with your cable, it may have gone bad. However, sometimes it’s just a matter of making sure the inputs are plugged in correctly to get it to work. If you have checked that and still experience symptoms, then you might need a new cable.

Common Causes of Damage

We mentioned some of the usual causes above, but will go into more detail here. If you don’t take care of the input connectors, you may need another cable much faster. Coiling or bending the cable is not recommended because it could cause wear over time.

Be gentle with your HDMI cable. Although they were created to be very durable, you still need to be careful when you plug and unplug them from your device. Make sure you do it slowly and gently to not damage your device or connection.

They are robust, but HDMI cables are not meant to last forever. Another common reason for these problems could be heavy use over time.

Test to Identify Source of Damage

Now that you are sure you have a bad HDMI cable and it isn’t just poor connection or incompatibility, our experts will help you identify the possible issues and present solutions and easy fixes.

Possible Issues and Solutions

Sometimes simply looking at the cable or your device can show the issues very clearly. If you have your cable coiled around something and is tangled up, it could affect the video and audio connection, which would explain the blurry picture and low resolution. 

Check the pins in the inputs of your HDMI cables. These pins are the connectors which relay signals. They are small but crucial to the overall function of the HDMI. Check to see if they may be bent or broken. Your resolution will suffer if the even one pin is not matched up correctly.

Is the cable properly plugged in? Look at the back of the device to make sure it’s securely fastened, whether it’s your receiver or your television.

Although many devices support HDMI cables, incompatibility could also be a problem. Check to see if the devices have an HDMI port. Sometimes it’s just a matter of compatibility. If it’s HDMI HDR issues, you need to check to see if your devices are HDR compatible.

Also, check your video resolution settings. You need to be sure the devices support the same output and input settings. No picture and sound are telltale signs of unmatched input and output settings.

If you suspect but aren’t sure if the cable is the problem, you can test out your theory with a different HDMI cable if you have one in your home.

Check to see if software updates are needed. This is one problem that’s often forgotten and it could just be a matter of not keeping up with the updates. 

Buying a New HDMI Cable

If you have decided to buy a new HDMI cable, then there are a few things you need to ask yourself to make sure you are making the right decision. Think about what version you want in your home. You have to consider the device you are connecting, and the picture quality of your content to help you decide on a new version.
