If that sounds like what you are looking for, let’s dive right in!
Onn TV Problems and Troubleshooting Steps
Below are some common Onn TV problems and how to fix them.
Problem 1. Onn TV Black Screen
This is one of the most common Onn TV problems reported by users.
With this issue, the TV actually turns on (the LED light is on), but the screen is totally black.
In some cases, you may hear sounds coming from the TV. In other cases, the sound may not work as well.
Causes or sources of the black screen issue include faulty power cables or power outlet, software glitch, HDMI cable and HDMI port issues and faulty backlight.
It may even be caused by issues with the remote.
When that’s the case, your TV will remain in standby mode (led light on with no picture). Then, when you try to turn it on with the power button on the remote, the screen remains black because no input is actually being recorded from the remote.
So, what are the troubleshooting steps for Onn TV black screen problem?
Here’s a complete troubleshooting guide for Onn TV black screen issue.
While the guide above is more detailed and explains all the steps in more details, some of the fixes are also highlighted below.
Fix #1. Power cycle your TV
Here’s how to power cycle your TV (also known as a soft reset).
- Unplug your TV from the power outlet
- Leave it unplugged for 30 seconds
- Press and hold down the power button on the TV for 30 seconds. This will help to dissipate the left over charges.
- After that, plug the TV back in and turn it on.
Fix #2. Check the Power Cable and Outlet
A faulty power outlet or power cable can cause a black screen, as the TV may not be getting enough power to show pictures.
Therefore, unplug the TV fro the power outlet and plug it into another working outlet.
Also, inspect the power cable for any fault (physical damage). If there’s any type of damage along the length of the cable, you need to replace it with a good cable.
Fix #3. Check the HDMI Cable and Port
If you have a faulty HDMI cable, faulty HDMI port or you have selected an input source that is different from that which the
You can begin by switching your current HDMI cable into a different HDMI port, while making sure that the selected input source on your Onn TV matches with the port you have the cable plugged into.
If you don’t know the input source that your TV is currently set to, keep plugging it into different HDMI ports until you have picture on your TV.
Next, try using a different HDMI cable.
Also, ensure that the cable is securely plugged into the port for proper connection.
If your Onn TV says no signal, has horizontal or vertical lines on the screen, the HDMI connection is also very likely to be the source of the issue.
Fix #4. Ensure the TV remote works
Like I mentioned earlier, your TV may show a black screen because it is in standby mode and the remote doesn’t actually work when you try to turn the TV on with it.
Here are some quick things to try:
- Replace the batteries in the remote
- Reset your TV remote and fix stuck buttons. To do this, remove the batteries and press every button on the remote multiple times. Then, put the batteries back in
- Ensure there are no interfering objects
- Open and clean the remote
Here’s a complete guide on how to fix Onn TV remote quickly.
Fix #5. Perform a hard reset
Since you can’t see anything on the screen, the only way to reset it is to use the physical reset button on the TV.
Here’s how to reset Onn TV with black screen:
- First, locate the physical reset button on your Onn Roku TV (at the back or side of the TV, usually close to the HDMI port). You will need a pin or any tiny object to push the button.
- Once you locate the reset button, press and hold the button firmly for about 10 seconds while your device is powered on. When it shuts down, keep holding down the reset button until it powers on and shows the Onn Roku TV logo again. Then, you can release the button
- When the factory reset is complete, the TV will reboot twice and finally turn on. You will need to setup your TV again.
Fix #6. Check for faulty backlights
Faulty backlights are also a common cause of black screen issue (and display distortion issues) on Onn TV.
Here’s how to check if the backlight is faulty:
- First, make sure your TV is plugged into the power outlet
- Next, point a flashlight to your TV screen (you can also move it around the screen).
- If your TV backlight is working well, all you should see is the reflection of the flashlight.
- However, if you can see dull images on the screen while pointing the flashlight, then your TV backlight is defective.
In order words, your Onn Roku TV is on, but the backlight needed to show images is faulty.
The backlight can be fixed by replacing the LED strips on the screen.
Problem 2. Onn TV Won’t Turn On
If your Onn TV won’t turn on at all, it could be an issue with the power source (cable and port), power board or main board.
It may also be due to backlight issues.

Problem 5. Onn TV Keeps Turning Off By Itself
If your Onn TV turns off by itself out of nowhere, it may be due to issues with the power source, a faulty remote, faulty HDMI cable/port, overheating, connected external devices, enabled sleep timer, corrupt cache files/software glitch or outdated system software.
Fix #1. Check the Power Source
- The first thing you need to do is check and ensure that the power cable is plugged in tightly and securely into the power outlet.
- Also, inspect the cable for a visible signs of damage. If the cable is damaged/faulty, then you need to replace it with another cable.

Fix #2. Turn Off Sleep Timer
- To do that, go to Settings > System > Time > Sleep timer, and set it to “Off”.
Fix #3. Remove Batteries from Remote
The remote may be firing random signals to the TV, causing it to turn off.
This may be caused by weak batteries in the remote or stuck buttons on the remote.
So, go ahead and remove the batteries to see if the TV stops turning off by itself.
If you see a stuck button, try gently pressing it a few times to see if it pops back up. If that doesn’t work, you may need to clean it, use a pointy tool to release the stuck button(s), or maybe replace it in the worst-case scenario.
If the issue stops after the batteries in the remote are remove, go ahead and replace the batteries with new ones.

You may also stop your Onn TV from turning off by itself by actually power cycling it.
This works by fixing some software glitches or removing corrupt cache files that may be causing the TV to turn off by itself.
To power cycle your Onn TV, unplug it from the power outlet for 30 seconds. While unplugged, press and hold the power button on the TV for 30 seconds. Then, release the power button, plug the TV back in and turn it on.
Fix #5. Unplug External Devices
CEC-compatible external devices connected to your Onn TV may cause your TV to turn off by itself.
