Hi Paladin69,
This is likely due to an issue with HDMI-CEC. This feature allows your smart TV to be controlled by the Siri remote.
First, on your Apple TV under Settings > Remotes and Devices, ensure that Turn On Your TV with Your Remote is enabled.
For the second part of this you'll need to check your LG settings for HDMI-CEC and make sure it is enabled. This also should allow for volume control with your Apple TV remote with most tv models.
"Make sure that HDMI-CEC is on
If your TV or receiver supports HDMI-CEC, Apple TV uses the HDMI connection to allow it to be controlled by your TV or receiver remote.
If some features don't work:
- Make sure that your TV or receiver offers HDMI-CEC support. For help, ask the TV manufacturer or check the manual.
- Check that your Apple TV is connected to an HDMI port that supports HDMI-CEC. Check the TV manual to confirm which ports support HDMI-CEC.
- Check that HDMI-CEC is turned on in the menu of your TV or receiver. Use the remote that came with your equipment. Because manufacturers often have different names for HDMI-CEC, look for a setting that ends in "Link" or "Sync." Here are some examples:
- LG: SimpLink
- Philips: EasyLink
- Samsung: Anynet+
- Sharp: Aquos Link
- Sony: BRAVIA Sync"
If you're unable to find LG's version of this setting we'd recommend reaching out to LG.
Cheers!
