My 3 day old TV keeps restarting and not recognising connected sources. It started off fine but then started telling me wired connections to internet were lost. It also wouldn't recognise the HDMI Arc connection with my MS650+ soundbar. My Xbox one X, which was the main reason I bought the TV is unplayable as the TV switches itself on and off constantly. I followed detail set ups for my Xbox and at first it worked. Someone suggested turning Anynet+ HDMI-CEC off and that worked but it wouldn't recognise any devices. I have tried unplugging and plugging back in, things get solved for a couple of hours but then the problems start again. It even develops problems with HDMI ports that aren't in use. I spent a lot of money on TV, soundbar, rear speakers and new phone and am not happy with how things are going, please help.
