I bought a brand new Vizio 4k tv in February and everything has been pretty good so far with a couple problems, one was fixed by vizio customer service and the other wasn't. I tried relentlessly to find an answer to this with no luck. The problem is that it will randomly cut off picture and sound for exactly one second, kinda like it turned off then back on real fast, it doesn't happen alot, I'd say once a day at the most, theres nothing on the web about this so I don't even know if anybody else is having this issue or not. It'll do it with any video source too, I know 4k tvs are fairly new and the bugs probably haven't been worked out of them yet but if I could get a better idea of what it is then it would bring me closer to fixing it, thanks.
