I have been using my Roku for well over a year and suddenly it says insufficient power. I am using the Roku supplied USB cable AND the device is also plugged in to the power supply with the power cable provided. This just happened out of the blue. No red light on the device, everything is the same, just suddenly the power is insufficient, what can I do?
Sometimes just a simple unplugging of all the components and reattaching followed by a system restart of your device may help. Unclear when you say power cable, are you plugged into TV or the wall outlet. If TV, it could be the TV USB power port is developing a problem. Plug into wall directly after doing the above and see if that helps you.
Could also be the power supply cables and/or wall adapter have issues and could need replacing. (Roku website, walmart, best buy all have comparable replacement cables if this turns out to be your issue.)
I have had insufficent power on my Premier at times when the USB gets knocked loose from the power adapter at the wall from the animals running around. If the above doesn't work, then most likely device issue.
1. Make sure your device is updated to the latest version. If it is a software or firmware issue, then maybe addressed in update. Manual update>Settings...System...System Update..Check Now (press that button, you should get updated to 9.4 build 4200 or the like)
2. Do a System Restart.>Settings...System...System Restart
3. Hate this one>Factory Reset of Device. (need to setup everything again.)
4. Replace the power lead completely from unit to the wall. (For testing, in most cases the wall adapters for cell phones/tablets will work). As an additional test, I would plug the USB lead directly into my TV and see if results change. (that would indicate your power cable is most likely good, and just the wall adapter is bad. However, not all TVs can provide sufficient power so not a conclusive test if still fails...at this point it could be the power lead or the TV USB power port.)
That, I believe is really the extent of it from a user standpoint. As you perform the above procedures, you are narrowing down to a failing device. Not out of the realm of possibility. Here are the links for roku troubleshooting insufficent power and then link to products page for the power adapters w/power leads.
Continue to update if you need more help or find the solution to your issue.
We are having the same issue with one of our two Rokus, and it started the same time as all the others. Ours is a Roku Premiere we purchased less than 2 years ago. I have tried other power supplies and cables and it has not helped. Our other Roku is working fine. I think Roku may have sent out a flawed update. That is the only reason I can think of for them to stop working like this.
Kind of wondering if you noticed if this occured with all streaming channels or certain ones like Amazon Prime, Netflix (high quality streaming) or if you are streaming 4k. I have not discovered a "common" thread as such for the issue to develop. Although I can't discount an "update" issue, it definitely does not affect all the Premieres or mine would be affected as well. In other cases, people claim the update fixed their low power issue, so who knows.
I am more apt to think that if the actual USB cord and/or power adapter is not your issue, then the internal chipset regulating the power distribution may be the problem. I think this is why some people find streaming at lower resolution or even leaving their devices unplugged for a bit (like a day), sometimes help. Sometimes these chips just get heated to the point that they begin to malfunction or cause nearby components to malfunction. Its pretty jammed for space in the Premier's enclosure and no real place for the heat to dissipate. Sometimes just need a rest and good cooling period to see if they can recover.
My Premier can get pretty toasty warm with streaming, while my Ultra with all day streaming remains in the normal operating range regarding heat and temp. There is a menu shortcut where you can monitor these settings.
It is plugged into the wall using the Roku supplied power cord and adapter. I have tried others including the one from our other Roku with the same results. I should mention it also says it can not find our network. I am trying letting it cool down as mention above. If that does not work I will give up and try something else like Google Play or something.
Thank you for your help! No, It is not plugged into the TV USB Port. I am powering it by using the USB Power Cable that came with my Roku Express, that cable is plugged into the actual streaming player, then it is plugged into the Power Adapter that is plugged into the wall.
