Hi , have also a 65QFN and I am experiencing similar since the 1202.3 firmware. Intermitently, when I turn on the TV on an HDMI source, I heard the sound of the Tizen interface but the screen remains black no matter what I do. To get back the picture I have to switch to ambiant mode or switch to TV plus. If i a restart the TV it works too. It’s my second panel with the same problem so I think it’s a software related issue... is anyone of you experiencing the same problem?
