Ok, so randomly out of nowhere my RG6 run (thats in the wall) stopped working. It was tuner 2 of the HR20 in my living room. I thought it might have been a dead BBC problem...but it wasnt. I've checked everything outside and it all looks good at the multiswitch's end. Does anyone have any suggestions for me? The only thing that I can think of is to go out with my cable tester and unhook everything and see it i get a tone coming from that line.
