If none of the codes work, consider buying a (IR or Roku voice remote) or a universal remote that supports code learning (e.g., Logitech Harmony — discontinued but still available used) which can copy your original TCL remote’s signals directly.
Introduction Universal remotes are lifesavers when original remotes are lost, broken, or when you want a single remote to control multiple devices (TV, soundbar, streaming stick). TCL, a major player in the TV market (especially with its popular Roku TV and Google TV models), is frequently paired with universal remotes from brands like GE, RCA, Philips, One For All, and even cable/satellite provider remotes (Comcast Xfinity, DirecTV, Spectrum).
