Got my daughter's Sony PS2 that I'm trying to get working again. She had
managed to jam a CD-ROM in the sliding cassette tray. I got it apart and
fixed the mechanical problem. Also cleaned the lens carefully with
isopropyl alcohol. Reassembled and mechanically everything seems to be
working, but disc does not read. Instead, only a read error shows.
Can someone tell me the sequence of events when a disc is inserted? Mine
closes the tray, then briefly uses the laser to verify the disc is present
(this part seems to work fine). It then spins up the disc and the laser
assembly moves slightly up and down, but does not move in the horizontal
axis (toward the center or edge of the disc) at all. It just stays locked
in the near center . I can move this slide assembly manually by spinning
the drive motor worm gear so nothing is stuck. Seems it is not getting a
signal to the motor to drive. I see it uses a type of flat press on ribbon
cable and suspect it may be the cause.
How do I get the board out and in what order do these cables need to come
off and go back on? Thanks in advance for any assistance. I do plan to
attempt this when I get some time, so would appreciate pointers in advance.
