The sound quality of your Onn TV can be impaired or completely destroyed by the factors mentioned below.

  • If the mute button is turned on.
  • If the speaker does not work.
  • If any temporary glitch affects your TV.
  • If you hooked up your TV to a muted external device.

To troubleshoot sound issues in your Onn TV, ensure that the Volume is turned up. If it is, consider changing the audio settings.

Ensure the audio equipment attached to your TV and any audio connections, such as HDMI or optical output, are set to the correct input.

If nothing works, factory reset your ONN TV.

4) Onn TV volume problems/very low

Troubleshooting onn tv's issue

There are a few reasons your TV’s Volume might be too low. One possibility is that your TV’s audio output settings are too low.

Another chance is that your TV’s speakers are damaged or malfunctioning. It may also be that the sound of the show you are watching is low by default.

Here’s how to troubleshoot this:

  • Check if the Volume on your TV is turned down low.
  • If the Volume is turned up on your TV and you still have trouble hearing it, the next step is to check your TV’s audio settings.
  • If you have an audio receiver or sound bar, turn it on and set it to the correct input.

But if none of the above methods works for you, the show you are watching is low by default or your TV’s speakers are damaged or blown.

Try changing the channel or replacing the speakers.

5) Onn TV Black Screen problems

It could be due to several things.

The primary reason for a black screen issue is a loose cable connection. Aside from this, a bad power supply, malfunctioning remotes, faulty power outlets, or burned-out backlight is also responsible.

However, to troubleshoot this issue in your Onn Roku TV, ensure that the TV is correctly plugged into an electrical outlet and that the power cord is securely connected.

If the TV is plugged in and the power cord is secure, press the power button on the TV for 10 seconds.

If the power button does not turn on the TV, unplug it from the electrical outlet and plug it back in.

Once the TV is plugged back in, press the power button again.

If the TV still displays a black screen, try resetting the TV. To reset the TV, unplug the TV from the electrical outlet and then press and hold the power button on the TV for 30 seconds.

After 30 seconds, plug the TV back into the electrical outlet and press the power button again. If the TV still displays a black screen, there may be an issue with the TV itself, and you will need to contact customer support for assistance.

6) Onn TV stuck on the Picture screen

Typically this issue happens due to outdated system firmware and malfunctioning HDMI connection.

Possibly your TV is using outdated firmware or the HDMI connection is either loose or damaged.

On the other hand, mainboard faults or other hardware or system issues can also be responsible.

So what’s the solution?

Well, the solution is simple.

Disconnect your TV from the power outlet completely and wait at least 60 seconds. In the meantime, press and hold the power button on your TV for about 30 seconds.

Once done, power the TV back on.

Q: I can hear sound, but there’s no picture on my Onn TV. What should I do?

Start by checking the video source connection to ensure it’s securely plugged into the TV.

Additionally, ensure your TV’s firmware is up to date by checking for any available software updates from the Onn website or through the TV’s settings menu.
