An HDMI cable, abbreviated as “High Definition Multimedia Interface” cable, is used to translate high-bandwidth digital signals and bring them to your TV screen so that the TV displays it as a clear and striking image.
The most common type of HDMI cable is the “Type A” cable, which has 19 individual pins that connect to your television to transmit 19 different channels of information. One of the most common causes of these HDMI cables not working or providing a quality display is a break in the cable connector component.
While full replacement cables are not as expensive as they once were, single items such as exceptionally long cables or high performance cables deserve repair rather than replacement in terms of cost-effective services. It’s possible to replace the connector component without sacrificing the entire cable, and here’s how.
Step 1: make sure the connector is the problem
Before we can conclude that your lack of image or blurry screen is actually due to the cable connector, please inspect some of the other components of your cable and devices.
Check for bent pins or bad connections, which means the pins are fine, but there are no connections completely or securely on your inputs. Small things like the cable that is bent or inscribed too tightly can also cause intermittent image quality and display issues.
Step 2 – Cut the connector
Once you have ruled out other possible causes, disconnect the cable from the receiver or whatever device you are using to receive your signal (game system, cable box, etc.).
Take a pair of pliers and cut the connector at the end of the wire. Be sure to leave room to work so that you can easily splice a new connector.
To be clear, this refers to the end of the cable that connects to the receiver, not the end of the cable that connects to the TV or display device.
Step 3 – Purchase replacement connector
You will need to obtain a replacement cable connector for your current HDMI cable. You can go to an electronics store or use an older cable that is not being used.
- Caveats: If you use an old, working cable and amputate its connector, that HDMI may not be necessary. If it turns out that the problem was never the connector or you splice the new one incorrectly, you have destroyed the usability of two different HDMI cables.
The old high definition multimedia interface cable that you use must have a good connector that can be recovered. You can use an electrical current tester to determine if the connector is still workable for use with the broken HDMI. If it’s not good, go to an electronics store to buy a new connector.
Step 4: splice the new connector onto the HDMI cable
Take the replacement connector and connect it, joining the wires. Work carefully and carefully. You need to match all the corresponding cables precisely as any interruption will make the signal appear corrupted when you plug the HDMI cable back into the receiver and it will detect your TV. Use the electrician’s tape to cover the exposed wiring well before moving to the final step in this repair process.
Step 5 – Connect the cable to the HDMI receiver
After you have completed the broken HD Multimedia Interface cable repair, connect the cable to your receiver. Turn on the TV and check the picture quality so any picture quality problems that you had previously have been fixed.
