So some friend gave me is old PS3 (CECHH04) with a broken bluray. He tried to disassemble the drive to clean the lens without success. I ordered a new one on ebay and now the disc is spinning again when inserted.
Problem is, I can't figure out what is wrong with the top cover mechanism of the drive.
This red-lined part is the spring responsible for right arm touching the disc when inserted: slows it down/makes noise when spinning.
So I kind of changed the position of the spring to avoid this part touching the disc once loaded in the drive.
But if I look at some youtube videos, it's all wrong: the correct setup would be the one that is touching the drive. Because now the white arm isn't used to eject the disc like it is supposed to (not a real problem though, this setup works fine).
Do you have any ideas what I did wrong ? Do some moving part is missing ?
