A black screen or sometimes blue screen with sound on your ONN streaming device can be confusing—especially when everything seems to be powered on and connected.
This issue typically stems from insufficient power, loose HDMI connections, or software glitches.
Fortunately, most cases can be resolved with a few targeted fixes. Below is a step-by-step guide to help you troubleshoot and restore your device’s display.
Common Reasons For ONN Black Screen with Sound
Here are some of the common reasons why you see black screen on an ONN device.
• Low Power Supply – Third-party adapters or USB ports may not deliver enough power for full functionality.
• Faulty HDMI Connection – A loose or damaged HDMI cable can transmit sound but fail to deliver video. Sometimes the HDMI display port may not be working.

What To Do When ONN Streaming Device Shows Black Screen with Sound Issue
Follow this step-by-step guide when ONN streaming device is showing a black screen but you can hear sound.
1. Check the Power Source
When ONN device is showing a black screen with sound, plug your ONN device directly into a wall outlet using the original power adapter.
Avoid using third-party adapters—they may not deliver consistent power, which can cause malfunctioning of the system as well as affect video output.
2. Test Different Outlets
Try plugging the power adapter into a different wall outlet to rule out any issues with the current one.
You can also test with another compatible power cable and adapter to eliminate the possibility of a faulty power source.
3. Avoid Using the USB Ports
Do not power your ONN device through a TV USB port unless it’s specifically rated to provide enough power.
Most TV USB ports fall short, which can lead to partial functionality—like sound without video—or even long-term damage.
4. Check the LED Light
When powering on the device, look for the LED indicator on the ONN.
If there’s no light, it may not be receiving power properly. Try switching outlets or cables to confirm.
5. Check the TV Connection
Make sure the HDMI cable is securely connected to both the ONN device and your TV or monitor.
- Verify that your TV is set to the correct HDMI input.
- Also, inspect the ONN device and its cables for any signs of physical damage that could affect video output.
- You can also power cycle the ONN device and see if that works.
6. Reset The Device To Its Facory Defaults
If the previous methods did not work and you are still experiencing a black screen with sound on your ONN device, reset the device to its factory settings.
Here’s how to reset your ONN device:
- Locate the small reset button, usually located near the HDMI port or on the back.
- With the device powered on, press and hold the reset button for 5 seconds.
- While still holding the button, unplug the device from power.
- Continue holding for another 10 seconds.
- Plug the device back in while still holding the button.
- Release the button when the recovery menu appears.
- Use the reset button to scroll to “Wipe data and factory reset”.
- Press and hold the button to select it.
- On the next screen, select “Factory data reset” again. Wait for the process to complete.
- Select “Reboot system now”.
- Once the device restarts, you’ll be taken to the setup screen. Follow the prompts to reconfigure your ONN.
