Flashing white dots
Hi, When I turn on my Sky Q box I get noticeable interference in darker colours on the tv screen (flashing white dots) if I turn the box on and off anywhere between 1 and 15 times it eventually comes on with no interference and works perfectly for the remaining viewing . Any help with this annoyance would be appreciated. TV is a Samsung S90D 65" . Thanks .

I'm presuming you don't get this when using the TV's built in tuner or apps? It's possibly the HDMI cable, turn off the TV and Q box and take it out and replace at both ends, perhaps try a different TV HDMI port?
