My week old UEK49KS7000 has an issue where it will not come out of standby. When I try and turn it on the standby light and the screen just flash on and off constantly (as well as the samsung branding on the front) I have tried a different mains outlet as well as a new cable with no luck. I have also tried unplugging everything from the TV except the power lead but this also does not work. However somtimes it will just switch on and work fine, but I have no idea what is happening differently when it does this. I'm not sure if it makes any difference but it is connected to a PC/PS4 pro and and XBOX one. Many thanks. EDIT: forgot to add I have updated the firmware on the TV to what I assume is the latest version.
