Has your ONN Roku TV started unexpectedly restarting and you have no idea why? Don’t worry – you’re not alone. Many Roku TV owners face this frustrating issue.
In this comprehensive guide, we’ll cover the top reasons an ONN Roku TV keeps restarting and actionable solutions to get your TV working properly again.
Overview: Common Causes and Fixes for a Restarting ONN Roku TV
Before jumping into the step-by-step troubleshooting, here is a quick overview of the most common triggers of an ONN Roku TV restarting repeatedly and how to address them:
Software Glitches
Resetting your TV cache often fixes simple software bugs causing restarts.
Overheating Components
Allow the TV to fully cool off and ensure proper ventilation to prevent internal overheating.
Power Supply Issues
Inspect cables, try different outlets, replace faulty power boards if voltage is inconsistent.
HDMI-CEC Conflicts
Disconnect HDMI cables and devices to isolate control signal issues making the TV restart.
Outdated Firmware
Manually trigger a Roku TV update if automatic updates are failing.
Wrong Picture Settings
Reset picture modes to default if incorrect configurations are causing restarts.
Damaged Capacitors
Open TV to visually inspect for bulging or leaking capacitors and replace if found.

Detailed Troubleshooting Steps and Fixes
Follow these steps below to troubleshoot and resolve what exactly is making your ONN Roku TV keep restarting:
1. Reset Your ONN Roku TV Cache
Resetting your cache often resolves random software issues or glitches that lead to freezing and unexpected reboots:
- Press Home button on remote 5 times rapidly
- Press UP once
- Press REWIND twice
- Press FAST FORWARD twice
This restart sequence initiates a power cycle along with clearing any corrupted cached data.
2. Rule Out Overheating Problems
If internal components like CPU or memory chips overheat, the TV will reset itself as a protective measure.
- Ensure your ONN Roku TV has adequate ventilation on all sides
- Use compressed air to clean any dust buildup inside vents
- Consider adding a laptop cooling pad underneath to improve airflow
- Disable Energy Saving mode which reduces fan speeds
Also relocate the TV away from any heat sources making the temperature rise internally.
3. Inspect All Connected Cables and Power Sources
Loose HDMI connections or voltage fluctuations from overloaded power strips can trigger random ONN Roku TV reboots:
- Inspect and push all cables firmly into port openings
- Try different power bar, extension cord, and wall outlet
- Use a UPS battery backup to smooth electrical irregularites
- Replace any visibly damaged or worn HDMI and power cords
If TV stays on fine by itself, something in link to external devices likely the culprit.
4. Factory Reset the ONN Roku TV
If software corruption is causing infinite crashes and restarts, a factory reset should wipe these errors:
- From Home screen, go Settings > System > Advanced Systems > Factory Reset
Everything will be erased so backup Roku channels, preferences etc first.
5. Update ONN Roku TV Software/Firmware
Outdated firmware can sometimes lead to instability and freezing issues.
- Go to Settings > System > System update > Check now for latest firmware
- If problems updating over internet, download firmware onto USB drive from roku.com/link website using your Roku TV model number
- With USB inserted into TV’s port, initiate manual install under Settings > Systems > System update > via USB
Be patient as installing firmware can take 15+ minutes.
6. Open TV Case to Check for Failed Capacitors
Capacitors regulate voltage flow on internal boards. If they bulge, leak or fully burst then TV keeps restarting itself.
- Carefully open back case after unplugging and discharging TV
- Visually inspect all capacitors for swelling at the top or any leaks
- If any found, they must be replaced by soldering in new same spec capacitors
This requires advanced technical skill – have repaired by professional unless experienced with soldering.
7. Call ONN Support About Replacement/Repairs Under Warranty
If you have tried all troubleshooting suggestions and Roku TV still constantly restarting, then internal electrical fault likely.
Contact ONN support about replacement options if under 1 year warranty at:
- Phone: 1-844-334-2355 (9AM-9PM Eastern)
- Email: customerservice@onntvsupport.com
Provide your ONN Roku TV model # and overview of issue observed.
Other common problems like Netflix not working, screen flickering, or general Onn TV problems may require different troubleshooting.

Frequently Asked Questions
Q: Why does my ONN Roku TV randomly restart itself when watching shows or movies?
A: This can be caused by software bugs, overheating issues, HDMI-CEC control signal conflicts or the TV’s picture settings being configured incorrectly. Try resetting the cache, allowing proper ventilation, disconnecting HDMI inputs one by one and resetting video modes back to default.
Q: Does low voltage from my electrical outlet cause the constant rebooting?
A: Yes, inconsistent electrical flow can lead to random crashes. Inspect all cables first, then try different outlets throughout your home. Consider adding a UPS battery backup to regulate voltages going to TV.
Q: How do I stop my ONN Roku TV from restarting after the initial boot/logo screen?
A: This indicates corrupted software or firmware. Factory reset the TV to wipe any damaged cached memory/data making it stuck at restart boot-up phase. Also try manually applying latest firmware updates from USB drive.
Q: Why is my ONN TV working fine then suddenly turning off & right back on?
A: Frequent rapid power cycling is a key symptom of damaged bulging/leaked capacitors on internal boards no longer smoothing electrical current properly. Carefully open TV to check all capacitors visually for any signs of failure, then replace.
Q: My TV keeps blinking on & off – why won’t it stay powered on?
A: Along with faulty capacitors, this can also be caused by inconsistent voltage delivery. Inspect all cables thoroughly for any pinching, lose connections etc diminishing power flow. Try different outlets in your home to test. Consider adding UPS battery backup if wiring is older.
