Query: Disappointing

I received this player as a prize, and was really looking forward to using it. It worked fine for about 2 weeks, then the "locked" message was displayed on the unit, and the tray would not open. I followed the directions in the manual, which didn't work. I unplugged the unit, which didn't work. Finally, I contacted Sony, who told me that it would need to be sent in for service. After searching for a solution online, I've found that this is not an uncommon problem. I wouldn't recommend taking a risk with your money on this Sony.
