Onn TV won’t Turn on (Simply do This)

It’s pretty common for an ONN TV to stop turning on.

Sometimes it’s easy to troubleshoot this issue but sometimes it requires some more DIY troubleshooting.

However, before writing this article, I looked at Onn TV’s user manual and several youtube videos related to this issue and also the discussion section.

Methods I am going to discuss here may not work for everyone. If you fail to troubleshoot the issue after reading this article, you need to send the TV to a repairer

Here we go, Let’s dive into it…

But why this Occurs?

Why is my Onn tv not turning on?

Several reasons exist when an Onn TV stops working. But the primary reason for this is a sudden power surge.

Aside from this, issues with the internal power board or power button, a malfunctioning power cord, or a malfunctioning remote can also be responsible.

Look at the bellow table:

Reason why the Onn TV isn’t working Solution
Power supply issue Check the power outlet, plug the TV directly into the wall, and ensure the power strip/surge protector is working
Remote control issue Replace batteries, use the TV power button instead of remote
Power surge/outage Disconnect the TV from the power outlet, press and hold the power button for 30 seconds, and then replug the TV

Troubleshooting the Onn TV that won’t turn on

In short: To troubleshoot this issue, simply disconnect the TV from the power source and keep it unplugged for 60 seconds. During this time, press and hold the power button for about 30 seconds. Once done, plug the TV back on. Boom, your TV is working now!

Step 1: Is the power outlet or power cord working correctly?

You might have unplugged and replugged the TV many times, but it didn’t work, right?

You did this in the wrong way.

Here’s how:

  • Unplug the TV from the power source completely.
  • Keep it unplugged for about 60 seconds.
  • During this time, press and hold the power button for about 30 seconds.
  • Once done, plug the TV back in.

Now check if the TV turns on. If it doesn’t, proceed to the next step.

Don’t forget to check both the power cable and the power outlet to ensure they are working correctly.

Step 2: Check the TV’s power button

This step is especially for those, who use their TV using the TV’s physical power button.

Sometimes the power button gets jammed due to dust or gunk accumulation. When this happens, TV won’t power on no matter how many times you press it.

Press the button several times with some force and see if this fixes it.

Step 3: Check the remote.

That’s the point!

Rihan says,

“I was about to give up on my ONN TV, but then I had a wild idea to reset my remote’s battery. And you know what? It actually worked! My TV came back to life like Frankenstein’s monster of technology. Crazy, right?”

First, take out the batteries completely. Then press and hold the remote’s power button for about 15 seconds. Before putting the batteries back in, clean the batteries’ contacts and make sure the batteries have enough power.

Step 4: Check the Backlight

If your TV appears to have power and seems to turn on, but displays a black screen, it’s most likely due to a damaged backlight.

There’s an easy way to confirm this:

Power on the TV, then take a flashlight (the flashlight on your phone will work too) and shine it close to the screen.

Carefully observe whether you can see a very dim image on the screen. If you can, the LED backlight has been damaged. You’ll need to get it repaired by a skilled technician if that’s the case!


Q. Nothing worked! What to do?

There is nothing to do if none of the above troubleshooting guides work for you.

In this case, hand it over to a repairer, or contact Onn customer care if your TV is still under warranty. They’ll send you a new TV if they can’t fix it.
