I just want to say thank you so much for all of the comments and suggestions you have sent regarding my post.

I ended up doing four things (so far...)

-sending a formal complaint to the Better Business Bureau
-disputing the charges on my credit card
-writing a letter to "the Fixer" at the Chicago Tribune
-made a complaint with their consumer relations department, which only sent me a recording an hour later stating that the store is still refusing to take the tv back...

but...This evening I received a call from the general manager of the Addison, Il Best Buy location. He left me a voice mail and told me he would call me tomorrow to discuss the situation...So I'm keeping my fingers crossed that he (Tom Lopez) is going to make the outcome of this a positive one. If not, I am willing to continue to fight this until I receive a new tv or a refund on the broken one they sold me.

Again, I will keep everyone posted and thanks so much for all of your help!!! I greatly appreciate it.
