I lol at the fact you need to post to find out how to kill a tv
Just bash the bottom/back with the heel of your hand for a while
Pour water/other volatile liquids down the vents and turn on. Voila.
Hide the remote. Maybe the lazy asshole will just let it be.
Take the tv outside. Pour a BIT of a flammable liquid down the vents without letting the liquid touch the vents, or any other visible area. Drop a match. Hopefully that should screw it up enough, without too much visible damage.
If you're REALLY lucky it'll completely hollow out the inside...but probably not
