Answer to: PS3 Slim not reading diskTo those who change the lazer and it still doesnt work. Try putting the disc in the drive and taking it out again straight away. Repeat up to 20 times. I spent a whole afternoon trying to get a new lazer to work and thats what did it. Apparently they need to have a bit of power run through them first. Shout out to the people having this problem in 2016 took me 3 days of google searches and still found the answer on my owb pretty much.
