Numerous ports on your TV connect it to devices, and the HDMI port is one of the most important ones. This valuable port is on the receiving end for most modern devices. Sometimes, it may not work, so you’ll need to troubleshoot the issue. Read on to learn some common causes of a malfunctioning HDMI port on your TV and find the best way to fix it and regain your connection.
1. Handshake Issues
When two devices connect, they form a handshake and send protocols to each other to function. HDMI ports on the TV and connected device, such as a personal device or gaming console, will communicate and send audio and video data to the TV screen.
Nothing will appear on the TV if this handshake is disrupted, and the audio won’t project through the speakers. This handshake issue likely occurs because the device does not recognize the HDMI port’s High-Bandwidth Digital Content Protection (HBDCP). This encryption key is inside the HDMI signal coming from the port. You may need to change the TV settings or try a different connection on the TV to resolve the issue.
2. Damaged Port
A damaged port is a typical occurrence and may stem from various causes. The HDMI cable may move in a way that causes the whole port to loosen. If the port is loose, the connection to the TV is ineffective, and any devices will disconnect unless the cable remains at a specific position.
Water damage is another possibility that could prove dangerous to the port and a connected device. The electric current that carries the signal into the port will be ineffective because the water prevents a secure connection.
If water finds its way into the HDMI port, let it evaporate and dry instead of attempting to clear it out. Make sure the environment is cool and dry to prevent moisture accumulation. Remember, the port is like any other device and requires care to function.
3. Small Debris Lodged in the Port
An open port is susceptible to debris accumulating. Dust and other particulates are common causes of malfunctioning HDMI ports in your TV. Dust motes prevent the pins of an HDMI cable from connecting.
Occasionally blow into the port after periods of vacancy to dislodge any debris. If you notice dust surrounding the port, wipe the surface with a dry cloth or use canned air to clean out the port.
Make sure the HDMI port is the problem and not the device. You can do this by switching ports if the TV has more than one. This may resolve the connectivity issue and give you time to inspect the other port for the cause of the malfunction. Switching ports can improve the TV’s image quality since the operational one has a better connection. Malfunctions are common with technology, and troubleshooting your HDMI port is easier when you understand the potential causes.
