I have searched the Roku website, including accessories, and have not been able to find a power adapter replacement for a Roku model 4200x. Is there a compatible power adapter that will work with 4200x available for sale on the Roku website? Thanks.
@DBDukes observed that "The Roku 1/SE (2710), Roku 2 (2720, 4210), and Roku 3 (4200, 4230) all use the same adapter." - because he owns each of those units! So if you find a power supply for any of those, it should work for all of them.
