It was only after I got a replacement Unit and tore the broken ones to shreds that I realized that was the problem.
Did they replace this? Because it's not that uncommon for older electronics to be broken, in fact, it happens a lot. If this is the case, be glad you bought it from somewhere that would replace it.
If asked and they refused to repair/replace/refund, I wouldn't shop there anymore. There are a million other places to get the same items, with a guarantee, they're probably going to be cheaper, and they're going to care that you're satisfied.
