Hmmm, I've got a PS2 with a lens that has bubbles and scratches
in it.

blimey, what do you do to it? set it on fire then put it out by
scraping it with a nailfile??!! ;-)

it was "broken" when I got it. The scratches I can see from
somebody previously getting in there and fooling around. Which
they did. But the bubbles they've got me stumped. If I manage to
get a picture of the lens I'll post it.

I've seen bubbled lenses from owners trying cleaning fluids, and
also from focus or tracking drive faults, which have heated up the
focus or tracking motor coils, resulting in a melted lens. It's
worth trying a lens from a different laser ( assuming that there
are no drive issues that have melted or seized the lens suspension
). I have never cross-swapped between DVD and CD lenses, but in
principle, I don't see why there should be any fundamental
difference. For any chance of success though, note carefully what I
said about making sure that every last trace of glue is removed
from the lens mount, and the replacement lens lip, before fitting
it. It is essential that the lens is //absolutely flat// in the
mount. Arfa

I don't think a CD lens would EVEN work on a DVD, or vice versa. The
inner curvature of the two is different, yes? DVD's have smaller pit
size. MarkZ .
I'm not sure about the potential effects of that. Might work one way
round, but not the other. A DVD laser, for instance, will happily
play a CD or VCD.

That's true. Hmmm. Still, DVD players aren't optimized for CD's...

(sound effect of Markie weasling ;-)
