SV1730: I am getting sound from the SV 1730 to the second TV but no image at all. I have already double checked about the HDCP and my STB does not have it.

HDCP is only applicable with HDMI. Three things which have to be checked:

1. Are channels on both TRANSMITTER and RECEIVER set on same numbers?

2. Are the antennas aimed at each other? They should not be flat down but really aimed at each other.

3. Is the distance not too far?
