I have smart tv in living room that I have had less than 12 months, it was all working fine previously. It won't connect to internet. If you press home on remote nothing happens. Press settings nothing. Volume and channel up/down works. Power on off works 5mins after pressing it. Source doesn't work. It all works if I try my tv in bedroom. Tried my bedroom tv remote on my tv in living room and exactly the same happens only volume and channel up/down. Mute sign is flashing also? Message on screen says not connected to Samsung servers. If I turn my sky box on it picks it up and auto selects the source and I can watch it. But still no response from the remote except vol up/down. Used to be a sky engineer and used to tinkering with tv's...
