Realigning a new laser in SCPH-30001R
I recently replaced the laser in a SCPH-30001R, and realigned the laser so that it could read discs. After I realigned it though, it would only play PS1 discs and blue PS2 discs. When I would try to test a silver PS2 disc or my laser cleaning disc, the drive would making buzzing noises. (Versus no buzzing at all with the PS1 and blue PS2.) Should I keep trying to align it, or I'm I missing something? The laser model is a KHS-400C, the same model that I found in the system before replacement. When I first installed the laser without any adjustment to the laser angle, the system would not load any discs.
On a side note, I have another SCPH-30001R, that takes longer than normal to load a disc. Is there anything I can do to improve the load time?
