We bought the 55" NU7400 2 months ago and have now ran into this issue, however its worse. After working perfectly well for nearly two months we turned the TV on yesterday to find no apps would load, selecting an app would show the clicking-in animation to show you've clicked the app- but nothing would happen... no app would load. Additionally this also happend to any menu we wanted to load... whether that be the settings menu, wifi settings, guide or apps menu either from the remote or home bar. Now I mention this here because when we tried to load the netflix app the TV started behaving very sluggish and we then got the message for the first time ever stating we were low on memory and needed to delete apps to free up space, bare in mind we only use BBC IPlayer and Netflix. Never have we seen this message appear before, so is it just coincidence that we got the message as this problems just started to happen? Now we can't remove any apps because the TV won't load up the app section to remove them. We can't reset the tv because we can't get into any menu including using the remote. We phoned up support who gave us some secret remote combinations to reset the TV. However when pressing these combinations the TV went black obviously attempting to reset, but would then just return to wherever it was. All we can do is use the quick settings on the home bar, so we can atleast switch the source to sky but we're essentially locked out of being able to do anything else; no apps will load, we're out of storage space (after 2 months of use using only BBC Iplayer & netflix and lastly no settings menu will load or open up. Samsung support told us they would need to send out an engineer, when I asked whether this issue was connected to the 'low storage' space message they were unsure and said "we will need to investigate". After reading all these comments my gut feeling is telling me that our issue is connected to the memory problem that these 7000's have, so I'm probably just going to get it sent back for a refund and get a different TV from a different manufacturer. Such a shame... first samsung TV ever and pooooof.... gone in 2 months.
