Hisense "winking out" issue

[stevefp88]

I've got a new Hisense 75'' ADS panel from their ULED range, and whether I am streaming within its Google TV or watching from the connected Blu-ray player, the picture blink out for a microsecond. Sometimes this will happen more than once in a minute, other times it seems to happen once in an hour. It's so quick that I can't tell if the entire screen is going black or if it's dimming, but it's definitely disruptive to my enjoyment.

Is there a term for this drop-out behavior, and what are some possible causes for it?
