Hey @Philback37! Please restart the TV: unplug your TV from the wall socket > Wait 30 seconds, then plug your TV back in > Using your remote, turn your TV on. If this doesn't help, try resetting the Smart Hub instead: Menu > Settings > Support > Self diagnosis > Reset the Smart Hub.
As a person who has been dealing with this same problem for over a year, I think it's the software that needs to be updated because my Hulu app CONSTANTLY closes in the middle of me watching an episode of something and then I have to watch ads all over again. Please someone anyone that works for Samsung please fix this problem ASAP.
I have the EXACT same problem with my Samsung UN65MU8000 software version 1280.5 - About to sell and go with different brand, tv is less than 3 years old and they discontinue software/firmware support and updates? Forget this! Can’t ever watch an entire movie without this happening!
I hear you spent numerous hours performing manual updates, system restores, smart hub reset, direct Ethernet vs WiFi, cables, deleting. Cache etc Will not play 4K or hardly streams. Contacted Samsung was told my tv was 1 year to old for updates, firmware etc so was more or less screwed. Bought end 15 maybe 16 un60ju7100fxza UHD 4K 3d 240hz refresh rate tv for 2300 to be ahead of the curve when they all went that route to find this out! You have this tv and want 4K expect to by a separate streaming advice if you want to get close to touching what the tv should do. Still a sweet tv with a great picture none the less
I have the same model and same issue. I've had the TV for at least 2 years and tried all the methods you mentioned. It helps for a short while, but I end up having the same issue a month or two later. It's almost to the point where I need to buy a new TV. The picture is perfect, but the apps are almost unusable.
