my Roku 3930 X is connected to 4K TV, has been working fine for weeks but then started shutting down/going back to main screen after streaming show for a few minutes. same behavior on various channels. do i need to upgrade to a 4K Roku model?
How are you powering it? If you're using the TV's USB port try the supplied power adapter. If you're already doing that try one from a phone or tablet that can supply at least 1 Amp (i.e., Output: 5V 1A).
