I have a ps4 slim cuh-2015B. It was working fine, I was watching a movie on DVD and an update message came on. So no big deal I was going to fix me some food and so I started the update. Came back and it wouldn’t work and I had a error message su-42118-6 and my disc wouldn’t eject. So I go online to find out how to remove the dvd then find out what the error code was. It said the optic drive was bad. I called ps. I went through their bs and they say send it in. So I start doing research and I replace the optic drive, twice, still doesn’t work. Was very careful with disassembly and assembly, took pics and followed YouTube video for teardown and reassembly. Fairly straight forward. Still doesn’t work. So after more research I discover people are saying that the optic drive and board are serialized and must be replaced together which then I probably just need to buy another. Then I see that there are rumors going around that it was the update itself that screwed up the ps4. So what’s the truth? What is actually wrong with my ps4 and can it be repaired? Thank you for any help.
The optical drives are not serialized starting from a certain model of the PS4 non-slims where they moved the blu-ray drive controller circuitry to the logic board, older PS4 models had a little blu-ray drive controller daughter board sitting on the exterior of the blu-ray drive assembly. The problem is most likely the disc-feed motor + blu-ray drive controller board fuse on the logic board has blown. You’ll need to take it to a reputable console repair shop in most cases as this requires micro-soldering to fix.
