It turns out my older TV was only 3.5 years old, not 5 as I originally stated after finding the receipt for it yesterday. The 3-year protection plan from Circuit City had just expired a few months ago, and Circuit City isn't exactly easy to reach right now. Could I have been any more unlucky last week? Thankfully, I found a new and better TV at Best Buy today. I posted the details of it in the "What is the last thing you bought?" thread.
