I am helping my parents with their Roku Premiere (3920X) SN: K42077470863 and it was working fine for months and now goes into an endless loop of showing an Insufficient Power warning (no red light, but the unit is inoperable).
I have tried hard reset, changing the USB adapter, changing the cord, changing the outlet and nothing works. Given the number of other folks reporting the same issue, it seems like there is a larger issue here.
Not sure how to PM you, but I am only in town for a few days and would like to get a replacement unit shipped asap so I can help get it set up. Can you please let me know how this works?
We'd like to gather more information about the issue you're running into.
Is there a light showing on your device? How are you powering the device? Is it plugged into the TV USB port, or is it plugged into the wall outlet with the provided cables? In addition, have you tried using another HDMI port on your TV as well as trying your device on another TV to see if you are seeing the same issue?
Please let us know and we'll continue assisting you from there!
We appreciate you for posting regarding your insufficient power.
How are you powering the device? Can you please provide the serial number of your Roku device from Settings > System > About? I'll be able to pass it along to our Support team who can assist you further.
