PS5 ssd controller issue

PS5 Questions
1

Hello,

We have PS5 console which does not turn on (electronics student is fixing it). The SSD controller chip gets quite warm once power is plugged. We have found older schematics for it. This particular PS5 is CHF-20XX version with EDM-40 motherboard version. I just need some instructions which could clarify me is the actual SSD controller chip done or is it something else.

What is tested so far:

  1. drawn power is around 175mA and then drops to 10 - 9 mA.
  2. 12V does come from PSU to motherboard.
  3. SSD controller fuse is tested to be ok

If there is someone who is kind enough to point us some direction i very much appreciate it.

For slim model, initial current draw for boot sequence is normally around 2xxmA for 2~3 sec, compared to fat(EDM010/020//03X) Model 320mA.

What exact temp does that warm stands for? 40C(normal or 70C(hot)?

check uart code?

Hello,

Ok the power drawn is around there 2XX mA once plugged in and then it drops to 9-10 mA.
We do not have exact temp for you, but when i touch the chip with finger tip i can’t keep my finger on it for a long time (5-10 sec). My general guess for that temp is around 40-50C perhaps.

I am sorry that i dont have more accurate answers.

How do we check the uart code?

Here is a link where I posted a way to read out UART codes with a CH341A programmer:

Alternative for the PS5-Wee-Tools is a web interface:

Thank you for your reply. We need to wait for the USB-TTL adapter to arrive. Then we can test this out and see does this give us more information.

Hello,

We received the USB-TTL device and used it to read UART codes using “Console Service Tool” software. It gave us UART codes in STANDBY-MODE. There were many errors reagarding APU. One error recommended to check fuses F3501 and F7501. We checked those with beeper and those were ok. Also checked fuses F7001 and F7002.

We copied error codes to safe place and cleared existing error codes. Then runned the process againg but now it did not gave any errors in STANDBY-MODE. We pressed the power button no powering on like it was before and also no more UART codes received when pressing “Run” on the software. Did we do something wrong?

What would be the next steps what we should do? Or is there anything to do anymore? What i have read that if APU is gone then the whole board is only worthy for donoring components. Is it so?

Regards Kyltsi

POST the actual UART reading

That usually means the error codes you haveread were old code and you are having SB or most prior standby voltage(DA9081) issue which leads to SB unable to work/ generate new code

Hello,

Here are the UART codes from STANDBY mode as is (raw text).

End of errors.
Low: Nothing to concern about first.
Medium: Everything appears fine.
High: Console may boot but freeze or other issues.
Severe: Prevents console from booting.
Ignore Priority Status For Now. They are being updated!
[*] End Operation: Read Error Codes

From these we came to conclusion that the APU might be the reason since the fuses noted on the error codes were fine.

Any other thoughts about these?

After these error codes we couldn’t get more of the same errors to pop or any other error codes.

I would clear the error codes and see which codes appear again.

3x C0020303 and 80000009 in this sequence show up, if the PS5 get unplugged or lose power while running.

Hello,

We cleared the codes and read the codes again. It returned no error codes. How is that possible? We double checked that the RX and TX pins were correctly soldered to the motherboard and the gnd was also soldered to correct position.

And we are still on situation that console has standby power and after power button press no power.

Regards Kyltsi

TX and RX do they have 3.3V?

Disconnect the uart from the PC, connect the PS5 to the power, make several attempts to turn it on from the on button and then reconnect the uart to read errors
