I have looked through everything I could to find out how to add channels 3 and 4 I have a gaming joystick that requires tv to be on channel 3 or 4 I purchased an RF Modulator and the coax cable to attach it to the back of my tv everything is installed correctly I just can’t find out how to add channel 3 or 4 ?? Can anyone help??
I think you have to scan for channels from Settings->TV inputs and then it will ask if you need channels 3 and 4. It's been a while since I've done it.
That assumes the TV supports analog signals. I think the FCC allowed manufacturers to drop support a few years ago.
