So, I have everything set up and it works, kind of. The sound is perfect but the picture is a blurred, static covered mess. I've tried the troubleshooting tips listed online and nothing helped. I'm about to lug the old TV back up to my room so I can plug the cable into it to be 100% sure that there's nothing wrong with the coax connection. If that does nothing, I'm at a loss as to how to make this device work. Please help!
