To pair a Roku remote with a TCL TV, first ensure your Roku player is connected to your TV and powered on. If your Roku remote has a pairing button, press and hold it for a few seconds, and the remote should automatically pair with your Roku player. If the remote doesn't have a pairing button, make sure you're pointing it directly at your Roku player from a close range, ensuring there are no obstructions between the remote and the player. The remote should work right away without any additional syncing.
