Not every LG remote is universally compatible with any LG TV. Nevertheless, certain LG Magic Remotes boast exceptional backward compatibility and can effectively operate across various TV models and years.
You can easily check if your LG remote is working using your smartphone. Just point the remote at the camera on your phone, and if you see infrared beams on the screen, it means the batteries in the remote are working fine.
To connect LG TV to Wi-Fi without a remote control you can either use an ordinary computer mouse or use a universal remote control. You can also connect the LG TV to the Internet with an Ethernet cable.
