I have a Pioneer Mosfet 50wx4 Super Tuner III in my car. The CD player is not working after my battery died on my car and it keeps giving and 'error 12' on the screen. What can I do to solve this problem?
Error 12 is a read problem.
Most of the time it is an alignemt problem with the laser.
Sometimes it can be the mechanism, or vary rarely a dirty laser lense, or disc.
This error message merely means that it cannot play the disc. It is usually due to the laser diode inside the optical pickup head is weak, misaligned, or defective. But, it could also mean the tracking and focus adjustments have been jarred too far out. Or, it could be mean the servo controller for the head and motor drive has gone bad. Anything that prevents the system from reading the digital information on the surface of the disc will bring up the error code.
So, you must either have it serviced to find out the cause - or just replace it. This model is no longer current but there are many from Pioneer and others that could be an equivalent unit.
(i think) it typically indicates a mechanical problem or a problem reading the disk this could be due to dirt or debris on the disc or inside the player or it might involve an issue with the laser pickup mechanism.
