I unboxed my new 40" MU6100 and had it working perfectly for about 20 minutes.
It's connected to my PS4 and plugged into my WiFi hub with Ethernet cable.
Able to play on the PS4 for about 20 minutes, then the screen went black and sound stopped. At first I thought it was a loading screen or PS4 problem.
I've been out and bought new fuses, tried using different plug sockets, etc but nothing has changed (i.e. still a black screen).
I've tried turning on with control switch on back of TV, main remote and smart remote. TV doesn't respond (though red light on smart remote blinks after I press a button.
