Are you fed up because your smart TV is not working? There must be some problem with the HDMI ARC since it’s responsible for letting audio transmission to speakers and video on TV. They send compressed and uncompressed stereo sounds through a single HDMI connection. It creates the best surround sound along with a visual display.
When HDMI ARC does not work, you might hear the audio and video splitting. Therefore, I will lend a hand to you in understanding what can cause this issue and how to rectify it. Now, off we go!
What are the causes of LG HDMI ARC not working?
There are several reasons why HDMI ARC might not be working on your LG TV:
Incompatibility of Devices with HDMI ARC:
Not all devices are compatible with HDMI ARC. If your TV or sound system doesn’t support HDMI ARC, you won’t be able to use this feature.
Faulty HDMI Port or Cable:
If the HDMI port on your TV or sound system is damaged, or if the HDMI cable itself is faulty, this can prevent HDMI ARC from working. You can test this by trying a different HDMI cable, or by connecting the cable to a different port.
Incorrect Settings on External Devices:
If the settings on your TV or sound system are not configured correctly, this can prevent HDMI ARC from working. For example, you may need to enable HDMI ARC in the settings, or select the correct input.
Loose Cable Connection:
If the HDMI cable is not securely connected to the TV and sound system, this can prevent HDMI ARC from working. Make sure the cable is firmly plugged in at both ends.
Different High-Definition Settings:
If your TV and sound system have different high-definition settings, this can cause compatibility issues with HDMI ARC.
Glitches in the Device’s Firmware:
Sometimes, a glitch in the device’s firmware can cause issues with HDMI ARC. This can often be resolved by updating the firmware.
Incorrect Assignment of Input/Output Ports:
If the input/output ports on your TV or sound system are not assigned correctly, this can prevent HDMI ARC from working. Make sure the HDMI ARC port on your TV is connected to the corresponding port on your sound system.
How do I get my HDMI ARC to work on my LG TV?
If HDMI ARC is not working on your LG TV, here are some detailed troubleshooting steps you can try:
Check Device Compatibility:
The first step in troubleshooting is to ensure that both your TV and sound system are compatible with HDMI ARC. Not all devices support this feature. You can usually find this information in the user manual or product specifications. If either device is not compatible with HDMI ARC, you won’t be able to use this feature.
Check the HDMI Port and Cable:
A faulty HDMI port or cable can prevent HDMI ARC from working. To test this, try using a different HDMI cable and see if the problem persists. If it does, try connecting the cable to a different HDMI port on your TV or sound system. If the problem is resolved, the original port may be damaged. If the problem persists with a different cable and port, the issue may lie elsewhere.
Check the Settings on Your Devices:
Incorrect settings on your TV or sound system can prevent HDMI ARC from working. Make sure that HDMI ARC is enabled in the settings of both devices. On your LG TV, you can usually find this option in the ‘Sound’ or ‘Audio’ settings menu. On your sound system, the process may vary depending on the brand and model, so refer to the user manual if necessary. Also, ensure that the correct input is selected on your sound system. It should be set to the HDMI port that the TV is connected to.
Check the Cable Connection:
A loose HDMI cable connection can prevent HDMI ARC from working. Check that the HDMI cable is securely connected to both the TV and sound system. The connectors should be firmly plugged in and not wobble or come loose easily.
Update the Firmware:
Sometimes, a glitch in the device’s firmware can cause issues with HDMI ARC. Check if there are any firmware updates available for your TV or sound system. You can usually find this option in the ‘System’ or ‘About’ settings menu. Follow the on-screen instructions to download and install any available updates.
Reset Your Devices:
If all else fails, a simple reset can often resolve issues with HDMI ARC. To do this, turn off your TV and sound system, unplug them from the power source, wait a few minutes, then plug them back in and turn them on. This can help to clear any temporary glitches that may be causing the problem.
Repair and Replacement
If you’ve tried all the troubleshooting steps and HDMI ARC is still not working, it may be time to consider repair or replacement:
- Repair: If the issue is with the HDMI port on your TV or sound system, it may be possible to repair it. The cost of repair can vary depending on the specific model and the extent of the damage, but it typically ranges from $100 to $200.
- Replacement: If the HDMI port cannot be repaired, or if the issue is with the HDMI cable, you may need to replace the faulty component. A new HDMI cable can cost as little as $20, while the cost of replacing an HDMI port can range from $200 to $300.
