Hello!

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

#10 Re: PS4 SAC-001 brak napięcia USB

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

#12 Re: PS4 SAC-001 brak napięcia USB

by matic • 7 September 2017, 21:14
Of course, in Safe mode controller works only with USB cable my fault :oops:

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.

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.
