Input: I bought this after reading a lot of the reviews. While I did have some problems with it at first (poor customer service), everything has worked out great. I've owned this TV for about five years. After four years, I'm ready to toss it. One day -- literally one day, like so many others that I remember from my childhood -- while watching television (on cable) and turned on the TV, there was an unusual electrical buzzing sound emanating from the back half of the TV.
Output:
Bad review
