Fix #2: Use Another Power Outlet

Make sure the voltage output of the outlet matches the voltage requirements of your Onn TV model. Try plugging the TV into another working power source.

Fix #5: Check All the Cables

Another way to fix an Onn TV black screen is to check the ends of the signal cables or the HDMI cables if there are loose connections. If the TV screen is still black, you might be looking at a faulty TV power supply or hardware issues. 

Check if your TV is still under warranty with no physical damage, then bring it back to the store you bought it from with all the boxes.

Problem #3: Onn TV Sound Issues

For TV sound problems, try increasing the volume. Make sure the TV is not on mute. Do the same check for Bluetooth or external speakers. If a soundbar is connected to your TV, ensure the audio connections are plugged in correctly.

For Bluetooth speakers, ensure the TV and the speaker are paired properly. Try using a different speaker and see if that works.

Problem #4: Onn TV Connection Issues

Check if your smartphone or laptop can connect to your home Wi-Fi to isolate if your Onn Roku TV is the only one disconnected. Try restarting your Wi-Fi router after. Too many connected Wi-Fi devices may affect the signal transmission.

Problem #5: Remote Control Issues

Try replacing the batteries of the Onn TV remote with fresh ones. Check if the batteries are aligned to their proper orientation.

Problem #6: Onn TV Keeps Turning Off by Itself

For this, the first thing you should do is to disconnect all external devices. Other devices connected to your TV might disrupt its electronic components. 

Power off your TV first, then disconnect any external device like the soundbar, USB drive [1], or cable box/streaming device. Power on your TV after completing the power cycle.

Also check if sleep mode is activated. The TV’s sleep timers might be on. Go to Home > Settings > System > Time > Sleep timer to cancel the sleep mode. If these didn’t work, follow these fixes below:
