Posted in the another thread re same issue, then I found this one. Same symptoms. In Middletown, 3 systems went out early Tuesday morning. Chatted with Cox to no avail. Stopped by the Cox store in Middletown and swapped the tuning adapter (no change, surprise). Have a Bolt, Premiere, and HD…. It sometimes works if I unplug the power to the tuning adapter (on the Bolt system, haven’t found a workaround on the Premiere yet… except disconnecting the coax, but then you have no tv).
