Why your Roku keeps randomly turning off (and how to fix it)

Roku streaming devices are generally reliable, but users occasionally encounter frustrating power-related issues where the device shuts down unexpectedly. These random power cycles can stem from several factors, ranging from simple power supply inconsistencies to software glitches or overheating. To troubleshoot these problems, experts recommend first checking the power cable and ensuring the device is connected to a reliable power source, rather than a TV's USB port which may not provide sufficient voltage. Additionally, users should check for pending system updates, as outdated firmware can lead to stability issues. If the problem persists, performing a factory reset or clearing the cache might resolve underlying software conflicts. By systematically verifying the power connection and ensuring the software is current, most Roku owners can restore their device to normal functionality without needing a replacement.
