LG TVs run webOS, with the LG Content Store as their app source — setup follows a similar pattern to Samsung.
Step 1: Open the LG Content Store
Search for a compatible IPTV player in the LG Content Store and install it.
Step 2: Note your device key if asked
If the app displays a MAC address or device key on first launch, send it to support so your subscription can be linked to that device.
Step 3: Add your login details
Enter the server URL and username/password (or M3U link) from your order into the app.
Step 4: Reload the app
Restart it so the channel list and EPG load, then open Live TV.
