Sorry for the bump, but I'm losing my mind trying to figure this problem out. (preemptive apology for the wall of text that will follow) Jesus, where do I even begin....I wasn't really noticing a noise problem with my PS4, but against my better judgement I decided I was going to open it up and re-apply the thermal paste. All of the cool kids were doing it, and I wanted to be cool too.
Ordered the torx driver, MX-4 paste, watched a couple tutorials and did the deed. Everything went smoothly. Started the system up and put in Batman AK. Everything was great. The problem started when I tried to eject the disc using the eject button. It didn't respond...I got nothing. I had to use the system menu to eject the disc. I then tried to put in another disc and the drive wouldn't accept the disc. It's not like the motor was trying to push the disc back out, it just wasn't responding at all. Interestingly, when I would restart the system I would hear some mechanical whirring coming from the drive for a short time, but still the same result. I booted the system in safe mode and rebuilt the database. Same result.
Since then I've had the system apart multiple (and I do mean multiple) times checking and re-checking connections, re-seating the disc drive, and just about anything I could think of. I took the drive apart to check the gears and spindles. Everything checked out.
I have a second PS4, so I decided to open it up and swap parts around to see if that would help. I started with the ribbon cable and other connectors. Nothing. I swapped the entire disc drive into the original system, and.....nothing. Here's the kicker. I took the second PS4 and put all of it's original components back in, closed it up and turned it on... The. Same. Fucking. Thing. The second machine is now doing the same thing as the first. So now I have two systems that won't accept discs. I've been at this since last Friday and I'm at a loss. Soooo frustrated. Most of the info I get from web searches are the people that were having issues with their PS4's randomly ejecting their discs which it seems has been mostly resolved by Sony. Again, not the problem I'm having. If anybody can offer any assistance whatsoever I'd be ever so grateful. I'm open to any and all suggestions, information, leads etc.
Thanks for reading, and thanks in advance for any help.
