Well at least you didnt say the laser being 'out of alignment', one of the oldest myths in history. No such thing- the lasers are quite capable of aligning themselves, and do so thousands of times a second.
The dying laser one's up there though. The laser LEDs are rated for more hours than the carriage can ever see- early lasers became weak, which led to skipping in extreme circumstances, but you'll not see weak lasers killing a modern CD player for at least 10 years. Of constant use. Usually it's dirty optics- amazing how many CD players with 'out of alignment' or 'dead' lasers I've raised from the dead simply by opening it up and cleaning the lenses with alcohol and a Q-tip.
The internet says this particular error is caused by one of the hall-effect sensors giving a dodgy reading. Quite why they changed from microswitches to hall-effect sensors for servo positioning I'll never know- give me old-tech CD players any day- but I suspect it was due to cost. And their cheapness has come back to bite.. the consumer.
