My daughter was playing a music CD through the DVD Player on the aux inputs with this TV and she heard a pop and then the picture and sound went out. She and my wife unplugged it and I came upstairs to look at it. I plugged it back in and shortly heard another pop from inside the cabinet. We noticed the green power LED was flashing. I quickly unplugged it, and we haven't plugged it back in yet.

Any ideas on what could be the culprit?
