How to Fix Whenever Onn Roku TV Shuts Off Randomly?
Note: Have you tested if the onn Roku TV responds to the remote?
1. Reconnect the TV’s Power Supply Cable
You can address non-lasting issues with the onn Roku TV by temporarily disconnecting the power-supplying cord from the electrical outlet.
As a result, the TV’s residue power will be drained and all system services will be reset, hopefully preventing the random shutting down.
Follow these instructions to power cycle the onn Roku TV:
- Press the “Power” button on the remote to power off the TV.
- Disconnect the power adapter from the back of the device.
- Wait for a total of 60 seconds while your device discharges.
- Reconnect the power adapter back into the electrical outlet.
- Next, turn on the TV and check if it is still turning off by itself.
Important: Verify that the power cable is connected securely on both ends!
2. Disable the “Auto Power Savings”
The “Auto Power Savings” feature allows the onn Roku TV to power off as a result of not being used for 20 or more minutes.
Hence, disabling the feature will prevent the TV from turning off due to inactivity, which will solve the power off, but this will lead to a higher power consumption.
The auto power savings feature can be deactivated like so:
- Press the “Home” button on the Roku remote control.
- After that, navigate to “Settings” and select “System.”
- Next, select “Power” and go to “Auto power savings.”
- Uncheck the “After 20 minutes of no interaction” box.
- Allow the TV to idle for 20 minutes and test the problem.
If the problem is not power or system-related, the onn Roku TV should no longer power off by itself whenever not interacting with it for more than 20 minutes.
3. Check for a Newer System Version
If your onn Roku TV keeps turning off it could be an indication of an underlying issue with the firmware version.
If the TV has been operating on an outdated firmware build for a while now, a software conflict may be repeatedly causing the system to shut down without a proper reason.
Here are the detailed steps for updating the onn Roku TV:
- Press the “Home” button on the onn Roku TV’s remote.
- Scroll to the “Settings” section and navigate to “System.”
- Select the “Software update” tile and press “Check Now.”
- Wait until the onn Roku TV validates newer OS versions.
- Optional: Follow the steps if there’s a newer OS update.
Once the newest system is uploaded, the onn Roku TV will reboot after approximately 20–30 seconds.
Once the system has fully loaded up, check if the unannounced rebooting persists.
4. Inspect the Power Supply of the TV
Similar to other TVs, the power supply of the onn Roku consists of a standard 2-prong power adapter delivering an input of 125 volts.
If a loose connection, an obstructed power input, or a faulty external device is present in the setup, it could be repeatedly causing the TV to power off.
Hence, inspect the following connections and equipment in the TV’s setup:
- The power adapter’s connection to the onn Roku TV and wall outlet.
- The functionality of the electrical outlet where your TV is connected.
- The functionality of third-party electrical devices present in the setup.
- Inspect the condition of the TV’s power adapter and the power inputs.
We advise disconnecting all external equipment in the setup of your onn Roku TV while testing for faults, concerning the rebooting.
That includes all devices connected over HDMI, Optical, AUX, Component cables, or RCA from the back of the TV.
5. Check if Onn Roku TV is Overheating
The reason why your onn Roku TV shuts off randomly could be because of overheating.
You can effortlessly address issues with the TV’s internal temperature by first diagnosing the cause and following a simple guideline to reduce the heat’s impact.
Placing your hand on the rear panel of the TV is a quick way to determine if the onn Roku TV is overheating or not.
Most of the connected devices and/or electrical equipment should also feel hot to the touch if the internal temperature is elevated.
5.1 What Causes Overheating of the Roku TV?
The leading reasons for TV overheating include:
- Continued utilization of the internal components.
- Poor ventilation caused by dust buildup or debris.
- High ambient temperature or nearby heat emitters.
5.2 Ways to Prevent Onn Roku TV Overheating:
Follow these steps to effectively reduce the onn Roku TV’s temperature:
- Clean the ventilation openings of the onn Roku TV.
- Dislocate nearby heat conductors transferring heat.
- Ensure all third-party devices are also disconnected.
- Lower the ambient temperature by opening a window.
- Use an external fan to blow against the back of the TV.
Additionally, shutting down the TV and waiting for 30 minutes is another effective solution, but in the short term.
The goal is to identify what’s repeatedly causing the TV’s temperature to rise.
6. Force a Factory Reset on the Roku TV
If neither of the solutions so far had any effect, we recommend performing a factory reset on the TV.
This procedure will erase all of the onn Roku TV’s settings and uninstall all content that could be potentially causing issues.
However, this might just resolve the shutting down problem. Here’s how to perform a factory reset on the onn Roku TV:
- Press “Home” on the remote and scroll down to “Settings.”
- Select “System” by pressing the right arrow remote button.
- Select “Advanced system settings” in the options menu.
- Finally, select “Factory reset” and follow the steps to start.
Alert: Do not interfere with the TV once the reset starts!
7. Consider an Internal TV Defect
If the factory reset did not help either and the TV is still powering off by itself, there’s a strong possibility that the fault is hardware-related.
If that’s the case, we recommend directly getting in touch with onn’s customer support if your warranty is still active or taking the TV for servicing.
Warning: Disassembling the TV in any way will void the warranty!
