I have an Edge with Spectrum. About once or twice a week the tuner will randomly lose signal then reacquire the signal. This cycle is about every 75 seconds then the signal goes out again. The signal loss is only a second or two. This can happen on a core channel like ABC or Spectrum News, as well as other channels. Once the cycling happens I lose some of my channels all together. They simply won't tune in, or I will get an error saying the channel is temporarily unavailable. The channels are usually some of the pay channels or higher tier channels, but not necessarily SDV channels. I have had Spectrum to the house twice, I have replaced the cable card. When it happens the tuning adapter light will flash until the tuner reconnects, then the tuning adapter light goes solid again, and this will continue to cycle until I FIX it. The fix is as follows: unplug the tuning adapter and Edge, disconnect the usb cable from the edge, wait 2 - 3 minutes, not too soon or it won't work. Reconnect the usb cable and reconnect power to both boxes. Wait until the tuning adapter light goes solid green then all will work. That usually gets it going for 5 - 7 days. I was also having to remove the cable card every time, which is why I had it replaced. Anyone have a clue as to what's happening here. I am losing patience. Thank you.
