Advertisements Just got the bolt installed and cleared the channels (used one) then rescanned channels. I’m getting around 60 channels that it detects. when I check the signal strength, most of the channels give me 72. however, I can only seem to watch a few of the locals not all 60 channels. back to signal strength on a channel that’s not working, comes back as 72. Channel won’t display. why is the box finding around 60 channels but I can only watch a fraction of that list. Any advice??
