Your Blue Ray or DVD's are no longer read as before? The laser is an expendable part of the PS4 and must be replaced after some time.
We offer you here a replacement laser. Unfortunately there are several models of PS3 on the market with different lasers. Here we offer the KES496 Laser, which suits in PS3 Super Slim 4300 models.
But also other lasers are used in this model. Please get sure which laser you need by opening your console and check it. The laser number is printed on the laser.
All parts you buy from us have the usual warranty.
