guide for repairing a scph-30001R ps2?

[Emperor Bohe]

I've found multiple guides, but none cater to my ps2 (SCPH-30001 R). The difference is that the white gear is covered, even when the disc tray is opened. So how should I go about fixing this?

It would help if we knew what was wrong. And what white gear?

Disc read error. It can read the silver DVD PS2 games, but it can't read the blue disc PS2 games or PS1 games. The problem is, guides always specify to fix this you have to spin the white gear inside of the system. but in my specific revision, this gear is covered.
