Had the same problem with a broken PS4 I bought and fixed. I was racking my brain trying all sorts of things to get the disc drive working, replacing flex cables, cleaning connections, etc. I finally ended up almost completely disassembling it and I found that one of the side rods that holds the laser carriage had shifted off one of the set screws, thus throwing the lens out of focus, making it unable to read the disc. I shifted the rod forward back onto the set screw and whala, it worked perfectly! I hope this helps some of you guys out!
