No, all I got was a piece of felt, a brass weight and a screw. I've been
trying to find a diagram of that particular pickup online, to use as
reference, without any success so far.

I have a four-year old Aiwa/Sony shelf stereo. I am having a problem with
it. With some CDs, particularly some that seem a bit lighter in weight, I
am getting a horrible whining noise and sometimes the thing even starts
skipping.

I started to get rid of the thing, but after shopping around, I
discovered that it's superior to any other shelf system I checked out,
plus I determined that I simply don't have the space, resources, etc.,
right now to assemble a component setup in my bedroom, which is where
this stereo is. So I decided to keep the thing and try to get it fixed.

I know, from a Sony Technical Bulletin, that this issue is caused by an
oscillation problem with the specific Sony optical pickup (KSS-240A)
that's installed on the thing, that causes a mechanical resonance issue
with the discs as they play. I know, from a Sony Technical Bulletin, that
the fix for this is to add a brass weight (part No. 4-962-979-01) to the
pickup, and a felt washer (part No. 4-986-769-01) to the surface of the
clamper that touches the disc. The screw (part No. 7-685-134-19) that
adds the weight to the pickup replaces the screw that holds the PC board
with the pots to the laser.
I have these parts in hand from Sony, ready to install. I have spent the
morning trying to find someone to install them, since I've never done
this kind of thing before. I've discovered that no one works on stereos
anymore. I'm not surprised of this, because I'm sure they're considered
kind of disposable. But I don't want to dispose of this one when all that
needs to be done is a piece of brass screwed in somewhere and a piece of
felt stuck somewhere.

Let me take that back, there is one person in my town who will do such
work, and he's very good and quite cheap. The only problem is I might get
the stereo back around Inauguration Day ... of 2013.

So, is there anyone out there who could clue me in on just how big a deal
what I have described is to execute, whether it's something a
do-it-yourselfer should even attempt or should I still beat the bushes
trying to find somebody to do it. And if it is something simple that I
could do, could you give me "See Spot Run" simple, hand-holding
directions, starting from the moment I take the first screw out of the
thing, as to how I do it, what exactly I need to look for, what do I need
to be careful of, etc., because I really don't want to trash the thing
trying to fix it. Because I really have no clue whatsoever where or what
these specific things (clamper, PC board with pots, pickup, laser, etc.)
are or look like.

Thanks in advance for any help.



Did it come with any instructions? If you have a screwdriver you ought to
be able to fix this yourself, it should only take a few minutes. If you're
really that much of a newbie, I suggest finding someone local to help,
don't you have any engineer or handyman friends or neighbors? It would be
very hard for someone to give you such detailed instructions over the
internet without being familiar with that particular unit.
