Power Supply Details

Model 3920X. Bought not quite a year ago at Best Buy. I do get a dim green light on the front but on the TV the Roku doesn't appear as an option. Guessing the power source. Where can I replace that? Details I need to look for, like what do I call the shape of the plug? Thanks.

Re: Power Supply Details

Any USB power adapter that can supply at least 1 Amp should work.  You may have one lying around from a phone or tablet.
