I have a Coby 39" TV with the numbers TFT LED TV 3916. ;My son has the remote and I am trying to hook it up to Verizon without using the remote. What source do I use to hook up the cable? HDMV1? I attached the cable wire from the Verizon box to the TV ANT outlet (the only outlet that screw in) on the TV but am getting a message of no signal. How do I know if the TV is set on channel 3?
