I was playing and left a game on pause for awhile, when I came back the music wasnt working anymore... and only after restarting it stopped reading cds. Now every time I reboot (but not after resetting) it still spins them for a few seconds before notifying the drive is empty.
Never had this issue before, does anyone know what the problem is ?
Guess I need special equipment for that, or is it doable without ? (Other than the swap mod, I dont have any experience)
Firstly clean off your laser lens with isopropyl or a lens cleaning fluid just to make 100% sure its not a speck of something that's moved on to the lens.
You can adjust the pots on the laser assembly and try to do a blind calibration with trial and error. It can be pretty infuriating though if it ends up taking a while, but occasionally I've hit the sweet spot after a couple of attempts.
Of course you'll never get the accuracy you would by properly calibrating the laser, but buying a decent multimeter, oscilloscope and a laser power meter even 2nd hand is reasonably expensive and only really worth it if you have a LOT of optical devices around your home.
It could be worth looking for any high-end hifi repair places in your area that service CD players, the guy near me gets quite a lot of games consoles through his door, they'll also be able to tell you if it's naturally fallen out of calibration or if the laser is dying.
