Its a rich school you say? Keep the TV and sell, don't return it. Odds are in your favour, you can get away with this. Turning yourself in, or trying to return it without anyone knowing is most likely going to get you f*cked. Take it from me, I turned myself in for something and thought because I did I'd get off lightly, but I ended up getting suspended for 3 weeks. You most likely will get expelled (considering you 'broke' in) and will also be charged. A person with high morals (like most of the people who have, and will post in this topic) will tell you to return it, but seriously, don't. Sell it. Get rid of it as quickly as possible. I hope this is all getting to you.
