A:AnswerThis happened to me the other day but I realized I had not fully connected the HDMI cable all of the way. I checked and I pushed the cable into the 4K player until I heard a click. After this it did not do this anymore.
A:AnswerI've had this issue, too, with another model samsung 4k player and my Sony TV. When my tv turns on due to the player being turned on, my tv screen constantly flashes. Must be some kind of bug Samsung needs to fix with an update. To fix it, I use my TV remote to turn the tv off and on again, but it's still annoying.
A:AnswerHello virginiavideo, I have attached a link below to available Smart applications, you can search by specific model number here.
