My freeview has stopped working. Was working fine up till 12 today. No sound or picture. Its saying there is no signal quality. Tried to do a factory reset and it searches for channels but still nothing. is it possible that the dish needs to be realigned due to the bad weather the last couple of days even though when it stopped working the weather wasnt too bad. Pulled out all the plugs and unplugged it then set it up again but still nothing. Any help appreciated.
