Hi guys
Can anyone point me in the direction of some test points and voltages I should be getting on the above ps5 .
No beep or lights getting 12vdc to the board and can’t seem to find any shorts
Struggling to get any guides on this version of the board
Many thanks
I would try UART. It will show if the southbridge is responsíve/alive and give you error codes, which could help to narrow the problem down.
Here is a setup for UART I use: PS5 UART Setup CH341A | GBAtemp.net - The Independent Video Game Community
Hi Calvin
Thank you for the reply
I’ve used the coder gui uart program but I’m having no success with it
It’s either I’m doing it wrong or there’s no com with the board due to southbridge not turning on .
I’m not familiar with using git hub etc I’ll get my head around that and see if I get different results ,
I was hoping to find a map of what voltages should be where
I’ll do some more reading and have a go at using uart again 
I would check if both pads for TX and RX have 3.3V.
The programmer should be set to TTL mode.
If only connect to GND and TX->RX CH341 at inserting the power plug into the PS5 on the terminal program (like PS5 wee tools) there should be an output after 5 - 20 sec:
OK 00000000:3A
$$ [MANU] UART CMD READY:36
No 3v on tx or Rx
Digging around I get these voltage readings
12v connected on the bench not switched on no beeps or lights just powered on the bench
If there is no 3.3V at TX and RX the southbridge is not powered or defect. So no beep and no light.
The pmic should show 3.3V and 1.15V. Are these lines shorted?
No shorts
And no 1.15 or 3.3v at those components
The DA9065 ic should generate the voltages for those lines.
If the 5V input reach the ic and the 3.3V output is missing without a short, I guess the DA9065 is bad.
I’ve ordered a replacement
I’m in the uk and can’t seem to get my hands on anywhere in this country
So Ali express and a bit of wait
I’ll update when I’ve received
Can I ask where you obtained the voltage readings from ??
Is it just a case of over time you know what should be outputting to where ? Or you have notes or a site with the info on ??
I intend to build my own notes from now on thank you for the reply’s it’s very much appreciated
FixMyApp on youtube is a good start for trouble shooting.
The standby voltages are one of the first things I check on defect PS5s if the system has trouble to boot.
