I need help with this same issue. I have a Roku Premiere and it is giving me the same message, out of nowhere. It was fine. It has been plugged into the wall the whole time, with the adapter that came with the device, using the cord that came with the device. I have unplugged, restarted, tried a different cord and adapter and keep getting the same message. Please help, thank you.
Could you tell us specifically the error message you are receiving? Please also reply here with the serial number/device ID of the affected Roku device. It can be located at the back or underneath the player itself.
With more information, we will be able to assist you further.
I also had this happen a few hours ago! At least I don't seem to be the only one.
At first, I got the "Low Power Input" warning. I plugged my Roku into the wall, and now the power light is back on. However, I'm getting "No Signal" from the Roku to the Television now.
I'm using a Roku Premier, serial #YH007F747981, and would really like to get it back up and running soon - I don't know what happened, and am wondering if there was an issue with an update or something.
Thanks for letting us know about the issue you're experiencing.
Most of the time, no signal message on the TV screen means you have the wrong input (source) selected on your TV. Make sure the source selected matches the one to which you have the Roku player connected.
You can also try the troubleshooting steps below:
The video cable is not connected properly or the cable is faulty
Check that the video cable is firmly connected to the back of your Roku player and to the HDMI or composite connector on the TV.
If you can, check to see if you have a faulty cable by connecting your Roku player with a different cable.
There is a problem with the TV
If you can, try connecting the Roku player to a different input on the TV to see if the problem is with the connector on the TV.
If you can, try connecting the Roku player to a different television to see if the problem is with your Roku player or the TV.
If all else fails…
Disconnect and reconnect all cables including the power cable.
Out of nowhere got an error that says:“Insufficient Power: The Current USB Port on your TV will not Power this Roku Device. Please use the provided Roku USB power supply”
I have restarted, unplugged, tried different adapter, cord, outlet, etc. Same thing. It was always plugged into the wall with the cord and adapter that came with the product. Never into the TV for power.
it is a Roku Premiere, purchased in February 2021, Serial # YH00G0368753
