Unhappy KSS-190A (Sony 557ESD/707ESD)

Hello all!

I bought a Sony 557ESD (707ESD) with the optical unit broken (I'll receive the player the following days). Not only that the laser is dead, the one who sold it to me also tried to fix it by turning the laser's power potentiometer.

I was thinking of fixing the current laser by changing only the diode... I found some Sharp LT022MC laser diode for sell...
Regarding the lasers' settings I read that it can be calibrated using a special CD and an oscilloscope. Can anyone give me some advice?

Did anyone around here manage to complete this laser diode switch operation successfully?

And for a simple fix, is there by any chance someone on this forum that has a optical unit for sale?

Thank you very much!

Please see this thread it has a collation of info on this subject. Unfortunately I doubt you will find a working KSS190A and I have never heard of anyone successfully replacing just the diode in an optic.

If you do manage it please report back as I am sure there are many DIY members who would be keen to hear how.
