Hello,

Sorry to hear about your trouble. It is not uncommon for Blu-Ray Disc Drives to fail, especially in devices like a playstation. The reason why these fail can vary from device to device, based on use, location, age, many reason. One sure indication though that this is simply a failed Disc Drive is the error messages "Disc Cannot Be Read". The 1st simple fix I would try is to get a can of air duster and blow out your Blu-Ray. ( Make Sure It Is Powered Off) If that doesn't work, then there are a few fixes, such as replacing the Disc Drive or the Laser that reads your Disc. Either way your Blu-Ray needs some maintenance.

Good Luck!
