The only way I can get picture is by letting the sleep mode screen saver come up or when I poked around and found the channel for the hdmi my laptop is on. Anything that my roku would be actively responsible for having picture is just a black backlit screen. I can see it dimming and brightening as I push buttons but still just black. I can hear sound just fine as well. It was working just fine before I went to bed and I woke up to it acting like this.
