Large working smart TV (Suwanee Georgia 30024)

I have a 48 inch Vizio TV. My two year old grandson has been watching this television to watch his educational programs. The complex where we live took over the Internet and now we're not able to get his programming on the Vizio because it's not a smart TV. Does anyone have a 48 inch or above smart TV that maybe you're going to give away or donate. I would greatly appreciate it.
