Default Trying to repair CD-player, genuine Sony parts??

**Have you removed the static protection link?

Apart from the packaging I have seen no extra parts on
the new device so unless it is hidden inside somewhere
there is no static protection link. But then I have to
admit that English is not my first language and I might
have guessed wrong at what you mean by static protection
link. My guess is it is something to protect the laser
unit from electrostatic discharge. The only such protection
I have found is warning text on the box and slight blue
tint to the plastic the laser unit was wrapped in.
(Yes I have used wrist band and anti-static mat.)

Recent development: I have revisited the possibility
that adjustment is needed rather than replacement. This
time around I have some luck with this. I can make the
player recognize disks it has rejected lately but in at
least one case it still refuses to play all tracks. I
have no service manual so I am 'driving by the back of
my pants' right now.


**Examine the two circuit boards (new laser and old laser) VERY carefully.
You will probably see a solder blob linking two tracks on the new laser
which is not present on the old laser. The solder blob must be removed for
correct operation.

This may help:
