Disc Memo "Fault" on Sony CDS-707ESD


Is anyone familiar with the meaning of this fault and also what the current laser pick-up is for this unit? Believe it was initially a KSS-190A. I am pretty inexperienced here. Believe there is also a problem with the transport screw as it does not seem to engage with anything.

I am eager to play it and compare sound. Thanks for any help.

If it turns out to be the KSS-190A laser, you'll be out of luck as they are simply unavailable. I know because I tried to find one for my Sony RAS-1. The closest I came was an NOS unit in Germany for $1,000 without any guarantee-no thanks!
The laser is not current as in not available anymore. What are you going to compare it with, have alot of lens cleaning fluid on hand.
