Hello Sky,
over the last week or so when watching Netflix or ITVx through the Sky box every so often the screen pixleates for a second or two, I Googled the symton and followed the instruction to turn every thing off especially disconnect the HDMI cable for at least 30 seconds infact everything was off for about 20 minutes, turned everything back on and its still happening, i have also checked all of our connections and all seems good, this is all through my main Sky box in the lounge with an OLED TV, but in an upstairs room we have another box with no trouble with an LED TV, do you have any idea whats causing this
