I had this compact stereo come in with the usual no play cd
symptom. took it apart to look at and clean the laser.
Closer inspection showed the top of the laser was flat instead
of the rounded coated lens that's usually on the top of the laser.
It also had air bubbles in the lens as i looked at it. I have never seen

one like this before. Could the lens be glued on and simple fell
off, or did someone try to clean the laser with some sort of solvent
and caused the lens to melt into itself? Strange.


I've seen that on a "new" PS2 laser from Ebay. Needless to say it
didn't work, solvent or heat are about the only things I know of that
can do this.

Anyone got a part number of this laser asssy?
Its got a sliding shield over the laser, and is MP3
capable. It does not look like the typical cheap
213 or 240 lasers.

Bob,

There's a service bulletin on this - the laser has to be replaced and a mod
done on the board underneath.

Warning:
The HCD-GX250 and 450 models seem to suffer from a variety of unusual
problems. I've been all over several of these. They are so bad that a cash
repair on one of these is simply too risky - it's highly likely the unit
will be back sooner, not later, and essentially be unrepairable. I'm going
to stop taking them in for cash repairs, and the warranty ones will go to
Sony in Laredo, TX.

Thank for the reply. I will probably give a high repair estimate with a
no fix recommendation. What exactly is the service bulletin about?
Is it about the laser lens? I just never saw one that looked like this
one. Its like someone dropped acetone or some strong solvent on the top
of the lens and it melted inward. With air bubbles embedded into the
plastic to boot. damnedest thing i have seen on a laser.

Bob
