I agree, partially, because I don't think you're an idiot. A idiot would confused the TV with a huge microwave or something...
But, you paid for the ticket! Also, the people is going to make comments all the time... and this is a very good example of it. Let's imagine you took the TV, maybe, someone will say that this doesn't look good or whatever, but now that you rejected it, MORE people is writing stuff about it.

We must try to do hard things because it's the right thing to do. If you feel OK rejecting the TV, that's fine! I cannot argue with your call since it was yours, but maybe, accepting the TV was fair enough, because you paid for it and the draw was fair and made publicly.
