Single mom here. My overzealous 11 year old accessed the service menu on my Samsung Smart TV and the HDMI ports (1 and 2 specifically) are messed up.

It's an F6300 series - UN40F6300AF. The warranty has already run out, so any help would be appreciated. Are there screen shots of what the settings should be? I'm fairly tech savvy and could possibly follow those???? If this is such a taboo area, it sure was easy for him to access it.
Let me apologize if this is not the correct posting place. I searched, but didn't see anything related. If someone else has links, I'll be glad to do the legwork. If no help is available, where can I take it to be fixed? My zip code is 29072.
Thank you for any help!
