TCL 75-inch Roku TV model 75S451 is not showing options to connect Bluetooth devices

Welcome, zoltarra 

You mentioned that your TCL Roku TV doesn’t display an option to connect Bluetooth devices. Just to clarify, were you able to connect a Bluetooth device before the recent software update?

Just as a heads-up: Roku TVs don’t support Bluetooth connections with standard devices like headphones or third-party speakers. Bluetooth functionality is limited to pairing with compatible Roku wireless speakers and soundbars.

You can get more tips here! Hope this helps.
