I’m having the same issue, all week every time I turn on my Ryukyu I get an insufficient power warning. I have tried switching the HDMI location, switching which USB port, it’s plugged into, I have tried plugging it into the wall, I have switched which adapter it was using, and everything is showing insufficient power.
I have done a hard reset on my Roku and it doesn’t help. This device is not very old, less than 9 months. My other Roku is working as expected. The previous one I had on this tv lasted more than 5 years. What am I supposed to do with this? 
it’s very frustrating that it looks like I’m not alone and that there isn’t a real resolution.
Are you talking about plugging in a Roku tv or the device. We are talking about when the tv is plugged into the wall here, correct. I don't see how the USB could possibly power the tv.
