Default sony laser

Forgive me if this has been covered but I have searched nightly for over a week and cant find it.

I need a replacement laser for a sony cfd-757 boombox. Its old but I want to fix it.

I believe I need the whole assembly as I am slightly inept.

Sony was of no help.

It doesn't look like a kss-213, I thinks its older.

Thanks for any help; here are some pics.

This is one of the discman lasers, probably a KSS331 or KSS220, but manual will say for sure. However, these are not very failure prone lasers, and faults are far more likely to be in platter motor or trackings sled motor, or simply sled mech lubrication. What makes you think laser is bad?

It won't try to spin the disc which I read elsewhere means the laser is not working. As a repair neophyte I am not sure what to check. What voltage do I put to those motors to see if they spin?

So I can't get the link/ download to work. Can anyone point me someplace I can reference this info without downloading malware simultaneously?

Sorry to hear you encountered malware from my link.

As I mentioned, I have used the site occasionally before and not had issues.

What actually happened out of interest ?

OK, I just had a look at the link and the files are .RAR so you need something that will open them. I thought they would have been pdf's and tbh I never looked the other day.

I didn't get any malware warnings downloading them and they (both parts of 2 part manual) scan as clean.

You need some program to open them though... google shows plenty of freeware for that if you want to pursue it

That doesn't sound good

I have nothing installed installed to open .RAR files I'm afraid.

The Laser is a KSM 360AAM according to the manual in my link.

Been playing around with some software (I use Acronis TI to undo everything afterwards) so remembered this thread and thought, why not !

Both .rar files have to be downloaded and then opened with a .rar file convertor to put them together into a pdf. No malware issues at all

If you want the pdf then pm me with an email address, I'll save it for a little while...

Only the circuit diagrams are shown, it's not the full manual.
