Just received our new tv , unboxed , connected all cables to One Connect, then go into setup , updated firmware as it was out of date. All connected was a film vis the usb port TV after 2 hrs of watching tv , the tv suddenly goes blank , re-boots, then we get a picture come up saying “check one connect cable is connected to tv”, so I switch off, disconnect cable,re-connect same message again “check one connect cable is connected to tv”.
Is the tv or one connct faulty , I cant go into any menu at all only the picture of the connect box appears: help please kids are going bonkers around the house no TV EERRRR
