I recently bought a TCL 55' C715. The remote is horrible, I have to point it perfectly direct to the TV so that the signals can be picked up. I also tried to programme Apple TV remote to control Volume, but didn't work at all. I have contacted TCL support and been waiting for a week now.
Any help here?
Cut a little piece of Tin Foil and glue it on top of the IR sensor on the TV. Angle it so it works when you press something. Else get a branded TV.
