Sorry, but with the digital signal change out in progress getting big TV's is just a matter of driving down the city streets on garbage day before the garbage truck gets there!
Easy pickens!
You get more out of it if you take it apart and sell the copper out of it there about 5lbs in it that's about 15 dollars. But you need to be careful it can hurt you even kill you.
I don't think anyone's going to buy your broken TV off you unless they know: what's wrong with it, how to fix it and that they'll be able to sell it for a huge profit when they've repaired it.
