A severe thunderstorm passed through my area Monday evening, knocking out power for a couple of hours. When power is restored, one Hopper comes up fine and the other keeps cycling on and off. When it cycles on I notice that PTAT is on two tuners, but before I can do anything, it cycles again. I hard reset, I unplug/replug to no avail. I call Dish and set up an appointment for Wednesday morning and unplug the offending Hopper. I plug the offending Hopper in before I go to bed, after PTAT. This morning I check and all seems well, Hopper comes on and acts normally. I'll check the Hopper when I get home tonight and see if it gets PTAT before I cancel the appointment tomorrow morning.
