LG TV HDMI Ports Not Working? Here's How to Fix

LG TV HDMI Ports No Signal or Not Working: Solutions

You can face the issue with LG TV HDMI ports due to damaged HDMI ports, incompatible HDMI cables, bugs, outdated system firmware, etc. Here are all the troubleshooting steps you can follow to fix this issue-

1. Check & Change HDMI Cables

Before you blame the HDMI ports, it’ll be better to check the HDMI cables as there are possibilities that they get damaged after prolonged use.

So turn off your TV and remove all the HDMI cables from the backside. After that, check if any broken pin or fault is visible on them. If you see any damaged parts, you should replace the cable rather than blaming the HDMI port.

LG TVs have 3 or 4 HDMI outputs, and you can use the alternative one to check if the fault is within the cable or the port. If none works, then using a different HDMI cable will be a good idea to know if the cable’s internal part is damaged.

2. Check the Compatibility Of HDMI Cables

If LG TV HDMI ports are not working, another possible reason is compatibility. But you will face this issue only if you’re trying to connect those cables for the first time. And if you have used the same cables, you should skip this method and follow the other fixes below.

Most of the newer LG TVs support HDMI 2.1, but you should check whether the TV box shows that it supports that. If you use HDMI 2.1 on an old model on your TV, your TV won’t be able to read the signals and show problems. You will have to get an HDMI cable that is compatible with your LG TV. 

3. Power Cycle Your LG TV

Something may also be stuck in your LG TV’s flash memory, preventing the HDMI ports from working correctly. In that case, power cycling will help you eliminate them and remove the residue power in your TV. If you don’t know how to do that, don’t worry, these are the steps that you need to follow:

  • First, turn off your LG TV and unplug the power cable from the power socket.
  • Then, you need to press the power button on your remote continuously for some time.
  • After that, wait around for a few minutes and plug in the power cable again.
  • You can turn on your TV now.

This practice will remove all the charge from your TV’s every component and give them a fresh restart. So, now check if the HDMI ports are working correctly or not.

4. Update Your LG TV’s Firmware

Many users have reported problems with the HDMI ports because of outdated firmware on their LG TVs. So, it’ll be worth checking that your LG TV’s firmware is updated to the latest version; if not, upgrade it.

To do that in newer LG TV models, follow these steps:

  • There’s a Settings button on the TV remote; press that.
  • Then, you need to select All Settings.
  • After that, select the Support option.

If you don’t know how to do that, follow these steps:

  • First, on your remote, press Settings

  • Then, navigate to the All Settings option.

  • Finally, your TV will pop up another window where you need to select Restart.

6. Contact LG Support
