PSP 1000 Lens Laser (KHM420AAA)
A complete replacement laser assembly for the PSP 1000 UMD drive.
Fits: PSP 1000 drives built around the KHM-420AAA laser. Check the number printed on your existing laser before ordering - the PSP 1000 shipped with more than one laser type and they are not interchangeable.
Symptoms it fixes: discs that spin but never load, "cannot read UMD" errors, and games that load from cold then fail once the drive warms up.
Worth knowing: this is the whole assembly rather than a bare lens, so there is no lens alignment to get wrong. The drive has to come out of the shell and the ribbon cable is fragile, so work slowly at that end.
