PS4 SAC-001 brak napięcia USB

Witam forumowiczów,

Mam problem jak w temacie , mianowicie mam PS4
z usterką braku napięcia na portach usb,

Czy ktoś miałby pomysł bo kręce się w kółko.
pozdrawiam

Hello!

Measure voltages to ground on pins 23, 44, 55, 58, 66, 83, 85 and 86 of USB controller chip GL3520.

in this mainboard no exist GL3520

My mistake, I thought is is SAB board...

On this board USB ports are connected directly to the southbridge BGA.
I would start with replacing the SB.

there is any way to confirm its a SB or only replace ?

I don't know if it is a way to confirm.
You can measure resistance to ground on Vbus pin and on all data lines of both USB ports. But I doubt they are shorted.

I think that on this board is only southbridge which handle with USB ports.
If it is not the SB I think it could be only corrupted FLASH.

i replace CXD90036G but console won't start
so am solder back old CXD90036G and console back alive but still no voltage on usb

i don't have idea wtf

If the console won't start with new CXD90036G you probably get a bad chip, or the reball was unsuccessful.

If you have an option order chip CXD90036G again from another vendor.

ok i replace another chip and back to the first point, console working but no usb voltage,

i measure data lines and they have no short to ground,

any ideas ?

If so I think that the FLASH is corrupted.

Go to "Safe Mode" and try options 4, 5 and 6.

i cant do that because controller not working no usb voltage and i cant pair it

Of course, in Safe mode controller works only with USB cable my fault

Unfortunately the FLASH content is married with APU and BRD drive Renesas chip, so it is no option to reflash it with dump from another console.

Sorry, I have no more ideas. I don't know if it is possible to repair the FLASH content or not.

thanks for all matic.

cable work flawlessly i tested ,

i need to resolve the problem not powering usb 5V but i dont have schematic,

maybe someone else has similary problem or have any ideas

It looks like that it is possible to repair the corrupted FLASH. ***Click***

P.s.: I have good FLASH dump from SAC-001 board, so I can upload it, if you need it.

udało mi się dostać płytę z uszkodzoną przetwornicą więc naprawiłem i zmieniłem ,

na chwilę obecną płyta zostaje jako dawca na przyszłość.

dziękuję wszystkim za pomoc.
