Hello all, first I want to thank all the people who helps others. I had learnt a lot on this forum, and signed up today to ask a question. I will copy-paste it since I’ve already posted it in another forum:
I am toubleshooting a PS5 with error SU-101312-8 that I bought for its cheap price.
I am in information phase, but already checked something:
- Thin ribbon cable from the 3 microswitches had no continuity as it has been crushed. I replaced it with hope but nothing happened.
- Ribbon cable from motherboard to disk drive board was damaged but had continuity in all its contacts. I strenghtened it with Kapton tape and it seemed to be OK. I’m receiving a spare one next week to replace it as well.
- Mechanical parts of the drive seems to be good. Power cables continuities are good.
What I have read from my multimeter is:
- I have continuity to ground (powered off) in DIFFERENT paths of optical drive board and PS5 board. I mean, If I put one probe in PS5 case, and the other in optical drive case does not give continuity. But it should, right?
- I found continity (PS5 disconnected from electricity) from Pins 1, 2 and 3 of the connector for the Optical drive unit, on the PS5 motherboard. I thought it was a SMD fuse but I did not check it yet.
- I’m pending to check this evening: with PS5 powered on, measure voltages on disk drive power connector.
Apart from that, my root issue is the same as many others observed: PS5 won’t accept any disk, it does nothing, eject button beeps, but does not activate the motor or anything. Because of that, I cannot update the firmware then I cannot play to CD games or downloaded ones.
I do not consider transforming the BluRay PS5 to digital one, I want to be able to read disks.
Given all the above, did any of you manage to solve an issue like this? I have trust in SMD capacitors/fuses under the disk drive power (the ones F5401 and F5402 referred by the user Calvin in several posts, I cannot post links, but they are too difficult to access to measure!), but the fact that having GND continuity for 3 out of 4 disk drive power pins crazes me a bit out…
Apart from that, is there any possibility to temporarily supply energy by jumpers to disk drive, just to test if the issue is the power, and eventually update the ps5?
Thanks in advance to anyone who reads this!
Edit: Important data, the PS5 is a 2020 unit, so I guess its EDM001. Also I have a spare PS3 slim MB, so maybe I can salvage any component from it.
