This frustrating issue has left many Onn TV owners scratching their heads and wondering what’s going on.

The good news however, is that I’ve found some proven ways to fix the issue, all of which I will show you in this complete troubleshooting guide. 

Without any further ado, let’s dive right in!

Onn Roku TV Flashing Red Light

The blinking red light on your Onn Roku TV means there’s a problem with your TV’s power supply, internet connectivity, or has encountered a hardware issue such as a fault backlight.

Follow the step-by-step troubleshooting guide below to fix the Onn TV red light flashing issue.

1. Power Cycle Your TV

The first and simplest fix you can try when your Onn Roku TV won’t turn on and keeps red light blinking is power cycling your TV. 

Power cycling your Onn Roku TV can help to reset the power supply and clear any temporary glitches that may be causing the red light to blink.

It’s a quick and easy fix that often resolves the issue, and it doesn’t require any technical expertise or special tools.

To power cycle your Onn Roku TV, follow these steps:

  • Turn off your Onn TV using the remote.
  • Locate the power cord at the back of your TV and unplug it from the power source.

  • Press the Power button at the back or bottom of your Onn TV for 60 seconds while it is completely disconnected from the power source. This will help release any residual power from the TV capacitors.

  • Plug the power cord back in, making sure it’s firmly connected to both the TV and the power source.
  • Press the Power button on your TV to turn it back on and that’s it.

If power cycling your Onn Roku TV doesn’t resolve the blinking red light issue, don’t worry! There are still other fixes you can try to get your TV Back to normal.


2. Check Power Cables

A faulty or damaged power cable can cause the TV to malfunction and display a blinking red light.

If power cycling your Onn Roku TV doesn’t solve the blinking red light issue, then you should try checking the power cables of your TV.

To check your TV’s power cables, start by inspecting the cable for any visible signs of damage or loose connections.

If you notice some damage to the cable, you may need to replace the cable entirely to fix the problem.

If there’s no visible damage, try unplugging it from both the TV and the power source and then plugging it back in firmly. Make sure the cable is connected securely to both the TV and the power source.

You can also try using a different power cable to see if that resolves the issue. 


3. Change Your Power Outlet

If the first two fixes don’t work, another option to try is changing the power outlet of your Onn Roku TV.

Sometimes, the issue could be with the power outlet rather than the TV itself.

Over time, power outlets can become damaged, which can cause power fluctuations that can damage your TV’s power supply.

So, if you suspect that the outlet you’re using is damaged, it’s worth trying a different one to see if that resolves the issue.

To change the power outlet of your Onn Roku TV, start by unplugging the TV from the current power outlet.

Then, plug it into a different outlet in a different part of the room. However, make sure the new outlet works fine. 

You can plug another electrical device into it to make sure that there’s no issue with the new outlet itself.

If the Onn TV turns on without the red light flashing when connected to the new outlet, you may have identified the problem.

In this case, you can leave your TV plugged into the new outlet or have a professional electrician repair the damaged outlet.


4. Disconnect External Devices

If none of the previous fixes have worked, another option to try is disconnecting any external devices from your Onn TV.

Sometimes, the Onn TV won’t turn on and keep flashing red light due to a conflict between the TV and one of those devices.

To start, unplug all external devices connected to your Onn TV, such as Roku Stick, gaming console, sound bar, and cable box.

Once you’ve disconnected all external devices, turn your TV back on and see if the blinking red light issue persists.

If the issue goes away, then one of the devices you disconnected was likely the cause of the problem.

In this case, you can try reconnecting the devices one at a time until you identify the one with the issue.

Once you’ve identified the external device causing the issue, try unplugging it for a few minutes and then plugging it back in to see if that resolves the issue.

If you still experience the blinking red light issue even after disconnecting all external devices, then move to the next fix. 


5. Restart Your Wi-Fi Router (If Connected to the TV)

If your Onn Roku TV is connected to a Wi-Fi network, restarting your Wi-Fi router can sometimes help resolve the issue, particularly if your Onn TV red light is blinking twice.

Here are the steps to restart your Wi-Fi router:

  • Firstly, turn off your TV by unplugging it from the power source.

  • Locate the Power button on your Wi-Fi router, turn it off, and unplug it from its power source.

  • Wait for about 60 seconds before plugging it back in.
  • Wait for the router to fully reboot and connect to the internet before turning on your TV again.
  • Once the router has fully rebooted, turn on your TV and see if your Onn TV is still flashing red light twice.

Restarting your Wi-Fi router can sometimes help resolve connectivity issues between your Onn TV and the router.


6. Reset Onn Roku TV

If your Onn Roku TV won’t turn on and is flashing red light, you can still get it fixed by resetting it using the reset button on the TV itself.

Note that resetting your Onn Roku TV will erase all personal settings, including your login information and channel settings.

Therefore, it should be your last resort and only be tried if the above fixes don’t work.

Here are the steps to follow:

  • Turn on your Onn Roku TV and locate the reset button on it. It is typically located on the bottom left or right corner of the TV, or on the back panel.

  • Once found, use a pointed object such as a paperclip or a pen to press and hold the reset button for at least 20 seconds. Be sure to hold the button down for the entire duration of the reset process.

  • Release the reset button and wait for the TV to turn off and then turn it back on again by itself.
  • After getting fully rebooted, check to see if the Onn TV red light blinking issue has been resolved.

Resetting your Onn Roku TV can often resolve various software glitches, including the blinking red light issue.

So, if you’ve tried all the previous fixes and are still experiencing the issue, this fix might work wonders for you.


7. Change Onn TV Backlight

If none of the previous fixes have resolved the Onn TV red light blinking issue, it’s possible that the backlight of your TV might be damaged.

The backlight is responsible for showing the pixels on the screen, and if it’s not working properly, it can cause the red light to blink continuously.

To check if the backlight is the culprit, you can shine a flashlight on the TV screen and see if you can make out any faint images or colors.

If you can see a faint image, it’s likely that the backlight is the issue.

If this is the case, you can try replacing the backlight of your TV. However, this is not a simple task and requires a certain level of expertise. If you’re not confident in your ability to replace the backlight yourself, it’s best to consult an expert.
