omg okay so i am so mad right now because its wierd but i have a roku stick 4k, and the light is being wierd first it shines white, then is flashing white, then it turns red and then black. and it keeps doing this. ive litterly never had issues with my roku tv until today, apperently i have low battery but the tv box DID NOT come with any sort of adapter. i went to support for roku and told them i have no adapter for my tv and they said something about using any sort of adapter to plug in your wall to charge my tv. because apperently my stick for the tv is in USB and doesnt have enough power. so i am confused. DO I USE ANY ADAPTER I FIND? yall help me out please.

@amelia2-

If you are powering your Roku by plugging into the USB port on the TV, try powering from house power via the USB power adapter that came with the Roku*. 

The ports on many televisions only supply 0.5 amp or less, which is not enough to power a Roku reliably. It may appear to start up okay, but when it runs into something that requires more power than the tv's USB port can provide, something's got to give. Frequently this results in shutting down the stream you are viewing and exiting back to the Roku home screen.  If this is a new problem, possibly an update to either the Roku operating software or to some channel app software is using a little more power than in the past.  If you were just barely scraping by before, this might push you over the edge. 

*If your Roku didn't come with an adapter, or if you don't have a Roku adapter handy, any other USB power adapter you have from another device should work as long as the fine print on it says it outputs at least 1 amp.
