My T2 has recently developed a problem when on freeview or replaying a video. Most but not all the time as it transits between adverts the screen goes blank with lots of snow and there is a sharp crackling sound much like a spark or short circuit. Especially on fast forward it is difficult to get it out of this mode other than by turning off the recorder. The TV also suddenly failed completely won’t even switch on. Has any had a similar experience? Is it terminal? I don’t want to damage another TV
