PS4 CUH-1215a optical drive replaced, still won't accept discs, help!
I was playing playing GTA Online happily one night, turned system off via controller menu after closing all applications, went to bed. Went to work the next day, got home, turned system on, tried starting GTA, and got a disc read error. Powered off the system, waited a few minutes, and powered back on. This time I got a message that the disc wasn't inserted, even though it was. I assumed the optical drive crapped out on me, since it wouldn't eject or read the discs... In fact, the optical drive was making no noise at all. So I ordered a new optical drive from eBay. While I was waiting for it to arrive, I tried all the fixes I could find... Booting into safe mode and rebuilding the database, reinstalling the system firmware, to no avail... I haven't tried restoring to factory settings yet, as my wifi is painfully slow, and I don't want to have to wait weeks for the rest of my digital collection to re-download.
Got the new optical drive in, and replaced it using ifixit's handy guide. :) I made sure all the cables were firmly connected, reassembled, plugged in, and prayed... new drive made no noise, and wouldn't feed the disc in. Crap. $100 wasted. I tore EVERYTHING apart this time, and looked over the motherboard, all the ribbon cables, etc... The ribbon cables all LOOK fine to me, no folds or damage other than the usual "guiding" folds. Checked out the motherboard, I see no missing or loose pieces, no scorch marks as if something overheated, nothing... Granted , I don't know EXACTLY what I'm looking at, but everything looked okay to me... I'm at my wit's end... I don't know why 2 optical drives are dead in the water... Do I need to just suck it up and order a new motherboard, or is there ANYTHING else I can try before shelling out more money? Help, please!
