    Okay, I'll add my two cents to the older posts...I have started having
    problems with my Sony CDP CX355 ("Mega Storage 300 CD). It was playing
    fine up until a couple of weeks ago, UNTIL: it began playing a disc,
    then jumping around on the disc, and then skipping to the next
    disc...same thing would happen. Sounds like this is a very common
    issue. I cleaned all the discs, even tried brand new ones.
    Ironically, this problem started happening two weeks after the end of
    the 1-year warranty (Sony must really know what it's doing :-(
    Anyway, called a local authorized dealer and one I found online and
    both said that it isn't worth fixing (I paid $180 for it, new.) I
    can't believe that this is a throw-away. Some of what I've been able
    to learn online is that dust and dirt can cause some of these issues.
    Problem is, I don't know what I need to clean. I hear laser pickup
    and objective lens and tracker, and mirror, but I am not sure where
    these are located, let alone how to clean. I suspect the problem is
    dust, because the house is dusty, but I need some good counsel here.
    Please give me some suggestions if you can help a neophyte fix this! I
    hate throwing more money at this.

    Quite likely the laser part # A3328818A, KSM 213 BFN/C2NP that's the
    laser, with spindle motor & sled motor complete. It's about $ 56.00 US
    retail, plus shipping & taxes,just for the part. It could cost you
    close to
    the price you qouted, unless you have a pal in the business. If it's
    bad,
    it's just as well to replace the whole laser mechanism...& it IS worth
    repairing,as long as it's in good condition! Did you clean it
    properly?

    The only thing cleanable with the type of laser fitted to that player, is
    the lens itself. With the player at rest, and no disc loaded, if you look
    for the small turntable that the disc rotates on when it is playing, then
    look below that, ( actually to the side as the deck is vertical ) you will
    see a black 'boxy' sort of structure, a couple of cms square. That is the
    top of the optical block ( laser ) and the lens is in the midle of that.
    Clean it with something like a Q-Tip moistened, not soaked, in electronics
    grade ( 99.7% ) isopropyl alcohol. Then polish with a dry Q-Tip. Don't be
    too violent, as the lens suspension is moderately delicate, but not so much
    so that you have to be particularly frightened of it.

    Failing that, you could replace the laser - it's from the cheap-enough KSS
    series, carried as Sony original and generic pattern by many suppliers, and
    a little label on the back tells you which one exactly it is eg KSS 213C or
    213D etc. Alternatively, you might want to replace the deck as a complete
    assembly. Although there is no mechanical alignment to carry out when
    replacing these lasers, and it is an easy enough job to do, by replacing the
    whole deck, you do get the added advantage of a new spindle motor, and new
    sled motor and drive gears. All depends on how much money you want to spend
    on it really.
