Playback Issues - Audio/Video & Power

[Krahnr]

My old Roku was making a noise and the screened was messed up when I turned it on. I replaced the old Roku with the Roku Ultra. I’m still having the same problem. I have to unplug it in order to get the Roku to work. I have replaced the cords, and adapter. I’m still having the same problem. How do I fix it?

I just purchased the Roku Premiere because my old Roku started making a loud popping, static, humming noise that was loud enough to wake the dead. The new one is doing the same thing. I have switched to a different HDMI port, thinking maybe that was the problem, but still the same horrible noise. The noise does not stop until I select an app and a program. I would love to know if this is a common problem and if there is a fix. I have a Samsung smart tv. If no solution, I may just go back to FireTV.
