Roku TVs Power On Randomly After August Software Update
Users report Roku televisions and streaming devices turning on unexpectedly in the middle of the night following the release of Roku OS version 15.3 in August 2026.
Software Update Linked To Glitches
Owners of affected units began reporting these disturbances shortly after the new operating system went live. The timing suggests a connection even though the update lacked specific autoplay features or power management changes. Experts believe software bugs often introduce strange behaviors without an obvious logical reason for the malfunction.
HDMI Connections Cause Phantom Power
Another plausible explanation involves the HDMI-CEC feature which links audio video components via HDMI cables. A glitchy signal within this chain can confuse connected devices and lead to random power-ups without user input. Compatibility issues between different brands often create signal miscommunication that results in this strange behavior.
Fast TV Start Feature Involved
The Fast TV Start setting keeps the operating system running in the background even when the screen is off. This proprietary power management allows instant startup but also keeps the device alert for voice commands to turn it back on. Some users find this feature causes the television to wake up without anyone pressing a button.
