That feeling when your brand new ONN Roku TV suddenly starts turning itself off and on constantly is enough to drive anyone mad. But before you get too frustrated, know that there are a few simple troubleshooting steps you can try to get your TV working properly again. This guide will outline the common causes and fixes for an ONN Roku television that keeps power cycling itself off and on.
Potential Causes of ONN Roku TV Turning On/Off Repeatedly
Before diving into the solutions, it’s useful to understand what might be causing these symptoms in the first place on your ONN Roku TV model. Common culprits include:
– Loose HDMI or power cables
– Outdated or corrupt software/firmware
– Overheating issues
– Factory reset got interrupted
– Bad capacitors on power supply board
If any of those components aren’t working properly, it can force the TV into a repetitive boot loop as the device tries fruitlessly to fully turn on. Thankfully this is usually fixable through some easy troubleshooting.
First Steps – Check Cable Connections
Since loose cabling is a common source of the on/off looping behavior, first double check that all cords are fully inserted into both the TV and wall/power outlets. Carefully disconnect them before reseating all HDMI inputs, power cords, and antenna/Ethernet cables. Securely push each connector straight into its respective port.
This simple step alone can often resolve temporary connection issues leading your ONN Roku television to get stuck in an on-off reboot cycle.
Force Close Apps and Restart TV
If firmly reseating wires doesn’t help, try closing out any frozen apps:
1. Press the Home button to access the menu
2. Select Settings followed by System > Privacy > Factory reset
3. Use arrows to highlight Factory reset everything
4. Press OK and confirm reset
Resetting the TV to factory default settings often clears out corrupt data causing activation troubles. After resetting, unplug TV for 60 seconds before plugging back in to restart.
Factory Reset the Roku TV
A related fix is performing a factory reset on just the Roku portion of the TV itself through these steps:
1. From Home screen choose Settings > System > Advanced System Settings > Factory Reset
2. Highlight Factory Reset and press OK
3. When prompt appears, select Factory Reset everything
4. TV will reboot into reset mode resolving glitches
This essentially reinstalls the Roku OS software fresh to purge out bugs without needing a lengthier master reset. If prompted, simply relink cable/power cords and re-activate the device as normal.
Check for Overheating Issues
Another potential instigator of cycling on and off is overheating, especially if housed inside an enclosed cabinet without ventilation.
Carefully feel around back of television checking for excessive warmth around the panels and upper areas. Also inspect inside cabinet for dust buildup blocking airflow around the ONN Roku TV.
If overheating seems apparent, relocate the device into cooler, more openly vented space before powering back on to resolve reboot looping triggered from heat-related shutdowns.
Contact ONN Support
If all else fails, initiate a service request directly through ONN’s customer support lines. Techs can further diagnose root cause (potentially hardware failure) and may recommend replacement if your unit is still under warranty:

While an annoying issue, an ONN Roku television endlessly turning itself on and off is rarely permanent and fixable through some easy troubleshooting techniques. Check cables, reset software, inspect for overheating and don’t hesitate to leverage ONN’s helpful support channels. With a few simple solution steps, you’ll likely have your TV operating normally again in no time.
