How to use remote to turn on cable and or tv I have 2 remotes 1 turns on box and 1 turns on tv. Then it just say no signal

The tv has to be on the correct input, if your tv has sevral.

There controller should turn both on and off. Left top system. When it says no signal just push the on button on front of box. I turn it on and off with the system button only

Check your input to make sure it's on the cable box. Its should be on the TV remote
