Answer to "Why is my power adapter overheating?"My Roku streaming stick is also getting hot after only having 3 weeks now. So hot that I have to unplug it because it has caused the TV to have glitched screens with random color blocks showing up. The other Roku TVs, one built-in and the other the HDMI stick with no power cable, don't have this problem. Switching to Amazon fire stick to solve this since no help from Roku or store technicians at multiple stores.
