If your TCL OLED TV has no picture or sound, ensure the power cord is properly inserted into the outlet. Also, verify that the source type is correctly set and the antenna is properly connected. Make sure the volume isn't set to minimum or muted, and that headphones are disconnected. The TV might be receiving a non-TV broadcast signal.
What to do if remote control does not work with TCL 43C631?
If the remote control for your TCL OLED TV isn't working, first check the batteries. Ensure that the remote sensor window on the TV's front isn't under strong fluorescent lighting. If that doesn't work, try cleaning the remote sensor window on the TV with a soft cloth.
