A faulty HDMI cable can damage your video and game systems. While a faulty cable will not cause any damage to individual components, it can render a system inoperable.
Most people don’t even consider the fact that the HDMI cable itself can cause problems.
Instead, they spend hours or days troubleshooting game consoles, televisions, and receivers.
If you are having difficulties with your AV systems connected via HDMI cables, consider the possibility of a faulty cable.
HDMI cables can cause several unique problems. The most common problems are no picture, blurry picture, faded picture, intermittent picture, and poor screen resolution.
These symptoms can also result from other problems. However, once you’ve verified the other causes, you can be pretty sure that the cable is the culprit.
What to check
Before actually testing the cables, you need to check a few things that could cause the cable problems.
If the cable winds up in tight coils or bends, you may solve the problems simply by untangling the HDMI cable.
If that’s not the problem, look for bent pins on the back of the components you’ve connected with the HDMI cable.
Your image will suffer if one of the pins is not properly connected to the cable.
You should also make sure that the connector cover on the end of the HDMI cable is not so large that it restricts the correct connection of the cable.
Because every TV, game console, and HDMI receiver is different, you may have a cable that is a little too large for your component.
It may take a little maneuvering for you to properly see whether your connection is secure.
How to test the cable
Once you’ve determined that the HDMI cable is most likely causing your AV problems, you’ll need to test your theory. Testing cables is easy. Here are two ways to test it:
If you have other AV setup similar to the one in question, you can change the HDMI cables to see if they work.
You will know they are faulty if the previously working system is not working with the new cables.
If you don’t have a similar setup, you can use a new HDMI cable in your existing setup.
You know that the original cables were faulty if the equipment started working properly.
Purchase HDMI cables
For buying HDMI cables, you should always buy ones that have been individually tested.
Many small electronics stores will do this, and most large store-bought cables will work just fine.
However, be sure to review the store’s return policy so that you can return any faulty equipment you purchased there.
Like many things in life, you get what you pay for. In the long run, it will be worth investing in a good HDMI cable.
