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?
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.
- 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.
Typically you press the remote’s power button to turn on the TV. But what happens when the remote malfunctioning?
That’s the point!
“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.
Q. How do I know if my Onn TV fuse is blown?
If your Onn TV suddenly stops working, there’s a chance that a fuse has blown. But how can you tell if that’s the case? Here are a few signs that your Onn TV’s fuse may be blown:
- The power light is off or flickering.
- There’s no picture on the screen, even when you turn on your TV.
- You hear a popping sound coming from your TV.
- Your TV smells like it’s burning.
If you notice any of these signs, check your TV’s fuse.
To do this, use a screwdriver to unscrew the TV fuse cap holder. Then, carefully check the fuse wire. If you see a visible gap between the wires or a metallic or dark smear inside the glass, you have a blown TV fuse.
Note: The TV fuse is located on the power supply board of the TV.

The TV turns on, but the picture looks fuzzy or distorted, which indicates that the motherboard might be damaged.
