Actually just to add to custardo's kick it advice. My DS2 (when he was around 2 years old) didn't like what was on the telly, went behind it (I wasn't in the room at the time, IIRC I walked away from him as he was having a big tantrum at not being allowed to watch Cbeebies) and pushed it off the stand and onto the floor (28 inch widescreen, old fashioned type with big back on it so no mean feat) and after we all got over the shock, comforted DS2 who was screaming his head off, tried the telly again and the fall had fixed a problem we were having with a whistling tube!
Not recommended though.
