I have 2 Roku Premier+ and 1 Roku Stick+. All 3 have worked fine for some time now. About a week ago one of the Premier+ started stating on the screen that is it overheating however I dont see the red light on the front. I have moved it to another tv to swap it with one working fine and I get the same thing. Doesnt matter what I do even if I unplug it for hours it tells me overheating on the screen within minutes of plugging it back in.
My Roku Premier has just started doing the same thing. I have 3 and the other 2 are fine for now. I have done all the recommended troubleshooting and still overheats.
