Hello, I would like to know if any of you have had my same problems in replacing the optical unit for the ps1 model SCPH 9000, and already the fifth spare that I order and that arrives not working.
thank you
Francis

Maybe they need to be properly calibrated?

don't buy the chinese clones, they are bad quality

hello I agree with you, but they are not found, think that it has already been bought 5 times, I tried to disassemble, but now solved put back its original with the calibrated lens now it is better, thanks for your answer.

in fact, as I said I tried to put the original back and clean the lens I brought it back to a value of 70 ohms and it is fine both on originals and mastered.
