I got to love my mom

Me and the kid's drop by my parent's house this afternoon. My mom has had this tv for a couple of year's. Not really sure how old the thing is but it is heavy as can be. She wanted to hook up her roku to it. I got the tv to work with a old DVD player. But some reason the tv won't work with the roku. Her new DVD player won't work at all with it. I didn't even change the channel at all. Let's just say it is from the stone age.
