Why is HDMI Not Working on LG Smart TV
There are many reasons why the HDMI is not working on your LG TV. Meanwhile, some of the primary reasons for this issue are as follows:
- Damaged HDMI cable or the port
- Outdated TV firmware
- Faulty motherboard or hardware failure
- Technical glitches
How to Troubleshoot HDMI Not Working on LG Smart TV
Refer to the troubleshooting steps one by one to fix the HDMI not working on the LG TV.
Replace Damaged HDMI Cable
If you use a damaged HDMI cable, your external device will stop working or even show a no signal message on your LG TV. In this case, replacing the HDMI cable is the only option to fix this problem.
On the other hand, this problem might occur due to loose connectivity of the HDMI cable. In such cases, disconnect the HDMI cable and connect it firmly to the LG TV.
Check the HDMI Ports
Similar to the HDMI cable, the next major thing you should look at is the TV’s HDMI Ports. Due to rust or any physical damage, the HDMI port on your LG TV will stop functioning. This results in the HDMI errors.
However, there is more than one HDMI port available on every LG TV model manufactured recently. So, if one HDMI port is damaged, connect the external device to another (HDMI 1, HDMI 2, or HDMI ARC/eARC) to fix the issue.
Restart the LG TV
Due to firmware bugs or temporary malfunctions on LG TV, the external device you have connected might malfunction. In this case, restart your LG TV to eliminate bugs, temporary errors, and unnecessary corrupted cache on your TV. Once the restart is done, access the external device and check whether it’s working.
Update the LG TV Firmware
Even software-related issues can cause your HDMI device not to work on your LG TV. So, the perfect fix for this phenomenon is updating your device software. As updating the software clears out glitches on your device, it is an essential fix you can try on. Navigate to the settings menu and update your LG TV firmware to the latest version to resolve the issue.
