The unit is over 10 years old and you have no idea how it was treated. It is quite possible the mechanism is dirty and the laser carrier won't move or the lens on the laser is dirty ... most likely both. Like it or not, you are likely going to have to have it pulled and cleaned ... and hope that's all that's wrong with it.
After listening to the clip, it sure sounds like a mechanical problem. Again, I think it's dirty and needs cleaning, at the very least.
