I’ve got a Samsung UE40D5700 set here. It had typical rebooting and so I flashed the nand. It powers on and I can watch tv, but I am unable to get a image with my fire-tv stick connected. I only see the amazon boot logo and then get a blank screen. So HDCP is not working. I get a picture when I connect non HDCP Receiver. Service menu states „EDID Sucess“ „HDCP Sucess“. So the key should Already be installed?
