I opened with no tv, and I bought one for my dayhome as there are times when we need it . If I have non nappers I use the tv so that the other children are not disrupted from kids playing during nap. I will sometimes notice we left it on by accident and while we are having 3:00 snack the kids might watch while talking to their friends,its not a big deal.
If the concern is the kids are watching too much tv , then I would suggest discussing that with your provider.
