We had Ignite installed on the 9th. Everything went reasonably well that day and the next. On the third day, the screen went black in the middle of a show in the middle of the afternoon. It stayed black until I unplugged the TV box (not the modem) and then plugged it back in. It has done this at least three or four times since. On the weekend I changed the connecting network from the one the tech set up to our established home network. Yesterday the screen went black again but this time after a minute or so it came back by itself. Is this a common experience with ignite users? When he installed ignite the tech said we had a very strong signal. Have these TV boxes been tested before they rolled them out?
