Need Help Fixing PS4 Optical Drive

So I have this ps4 CUH-1115a that I’ve almost totally fixed, works great EXCEPT for the optical drive(chip size BDP-025). It doesn’t accept discs, it’s almost like the optical drive is OFF when the rest of the console works fine. Eject button doesn’t work or make sounds like the power button does. The rollers are in place, I cleaned it out, the disc shield is down, the switches on the laser board aren’t stuck, the plastic tray is moving freely as it should, I took it apart and put it back together, there’s absolutely no visible reason whatsoever why it’s not working. The console doesn’t give me any sort of indication saying that there’s something wrong with it. I’m thinking it’s maybe the laser deck, but if that’s not it, then I’m totally out of ideas. Suggestions?
