Based on what I was able to pull up online, this seems like a common issue with Onn brand TVs. I suggest reaching out to Onn customer support directly to see if they can help, but it sounds like you have a bad board or screen on the TV.
You can try unplugging it for a minute or changing the HDMI cable if you haven't already and see if that helps.
