    Hi there sorry to bother you but i have a small problem.
    I have a CD/MP3/VCD player , everything was ok till one day when the
    Anti-shock disappeared.
    I went to my friend who sad that it just needs to be attuned, there is
    a diode(in form of a screw,at the back of the lens,that can be
    rotated).He attuned it for several hours and now the lens can't focus,
    on that diode are some signs(like 2,6, and an arrow, access my web
    page where i wrote a better description)

    Thx. for help.

    It ain't a screw!
    That is a potentiometer, which is used to set the laser current.
    If someone has fiddled with it, the laser and the unit is SCREWed!
