Hello,

I'm trying to figure out how to replace a laser diode inside a ps3 blu-
ray drive. I think I now know the best way to extract the diode.

My problem is installing the new diode; I have read in several places
that it's not simply a case of whacking the new one in, it has to be
aligned? Is this true, and if so, what would be the best way to go
about aligning it? How much is it likely to have to be rotated, i.e.
fractions of a degree or larger? I don't see that it can be rotated
that much as its degree of rotation would be limited by the flex cable
it's soldered to.

Many thanks for any help!
Nick

I've got a colleague who replaces many PS3 laser assemblies (I take it you
are referring to the optical head which runs on the deck within the drive,
not the *actual* laser diode ?) I will ask him what is necessary. Note also
that I think I recall him saying that there are two if not three different
variants, so make sure you get the right one. I have dismantled a number of
these drives to remove discs from PS3s suffering the YLOD condition. Be
careful when you replace the drive's top plate, as several bits of disc
handling mech, have to engage correctly with other bits on the main body of
the drive. Note also that once the top cover is removed, exposing the top
mech plate of the drive, the disc clamp just lifts away. It is not retained
by anything other than being 'sandwiched' between the mech plate and the
cover. When reassembling, it just sits on top of the (should be at that
point closed) lifter 'scissors'.

Hi Arfa,

Thankyou for taking the time to reply but it's the laser diode itself
I'm working on replacing. I can replace the laser assembly no problem,
however, it's not at all economical given the price of a laser
assembly so am trying to see if I can refurbish broken assemblies by
replacing the laser diode.

Thanks,
Nick
