I have had my QE55Q80T for about three months now, and really like it. However, recently when I switched it on using Freesat, I got a blank screen. I switched it off, and when I switched it back on it was ok, and that happened a few times. Now however, I just permanently get the No Signal message. I know it's not a dish problem, as I have a satellite box working perfectly, so wonder if there is anything I can do to check the problem.
