This unit needed a re-cap rather than new laser. Well, maybe both, but one should always start with rectifying obvious faults.
All small value SMD capacitors (10µF/16V and 22µF/6.3V) have ESR values from 3 to 10 times greater than specifications.
Sadly, instead of doing a re-cap, a guy who was not specialising in CD players undertook a "laser inspection", took the KHS-180A covers off and mangled it in the process. A AU$500 unit (2nd hand).
This is one of the reasons that lasers which are in finite supply are getting scarcer. Most people think that if a player does not read, it then has to be a laser fault. Which it might but also might not be.
I partly understand the guy though, because laser failure in SACD players is common. But I feel it was not in this case because and both guns are still firing well.
One can see this is not your run-of-the-mill $20 laser
