Successful replacement of the NEW Southbridge chip from China. Issue still remains though. But I have 4k ohms resistance to ground. When i feed it 12v of power @ 1amp. The board draws 54ma then drops to 22ma. Maybe the WIFI IC or the SSD controller.

Okay I think we are ready for chip orientation, flux and hot air. That and a whole lot of miracles haha

As Alex from NorthridgeFix would say " Better than factory"

NEW chip on LEFT. Re-Balled original chip on RIGHT.

Now i just have to mask the board. That's going to be a PITA finding the exact spots to mask.

it didnt run in Linux.
i probably could have if coder wasnt so "clever" and tried to download dot-net 4 for me!
i dont need it, i can do the same thing with MONO.

Probably just trying to save time and questions from Microsoft only fans.

the only dash to fix is the prius dash with the big vfd display.
they have a common fault of a BD3940 voltage regulator failing.
it's crap and i use a regular 78M05 to replace them

Oh nice. Good to know. Have you played around with that ps5 NOR modifer yet?

gotta be honest, if i get something that has the slightest sign that somebody has been fucking with any bga chips - i wont touch it.
i'v seen too much destruction in ps3's and xbox360's
another thing while i'm on the subject.
i wont touch car dashboards - they have usually been fucked by people trying to reprogram the mileage who cant solder and often dont even have the right tools.
there is a guy in my area - never met him but he has one hell of a reputation.
i think he ruins about 20% of the stuff he touches - he uses a fucking Portasol gas soldering iron to lift eeproms!!!!!

Yep Lesson learned on this one. Yeah I have been asked to fix car dashboards but kinda shrugged them requests off. Nobody has been persistent enough that I have had to tackle any. Yikes! That guy sounds crazy! Haha The chip is ready to grow some balls now. I am thinking of using the original chip first. Save the NEW reballed one. This masking pattern is going to be a bitch to hit all the correct spots lol

Lifted the Southbridge and boy did I find a surprise. Not only oxidized pads. But whoever worked on this before exposed the copper and put the chip back down. Explains the eratic intermittent behavior of this console. Now I have to refer to online pics of the traces and mask what should not be connected. Fun times.

Niooooce! Yeah I saw this on The Cod3r's site and grabbed it. Didn't try it yet.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

i always use the oposing colour - so i can see exactly where it is.
that said, i should get more, yellow or white could be usefull - i only have red & green currently.

Makes sense. Okay used the red. Cured it and put the foam and liquid metal back on. Now i draw 54 ma of current and as soon as i check the southbridge cap. Boom down to 26ma. I think we may have a failing southbridge that just becomes more degraded each power up. Thinking of lifting it and reballing by hand lol. Sick of waiting for stencil lol

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

well it may be caused by previous "cleaning",
it shouldnt matter as the chip is effectivly upside-down anyway.
UV solder mask may be a good idea, does it even need galium? isnt it paired against aluminium?
if it was that hot they could have used copper.

Yeah whoever tried to clean it before I got it probably didnt use a swab. That is what I was thinking. Doesn't seem to effect operation as of yet. But we also dont have a stable console yet. Well they call for liquid metal. Still trying to figure out these engineer's method of their madness. All i have is RED for UV Solder Mask. We will definitely add some color to it lol

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

some of those filters still have something on them - galium??
as for the die - i think it has a coating - maybe the coating is bubbling - cant tell from the pic

Stj,
This is a better pic. Took one with my anti glare light. Clean. The chip literally looks like it has a fingerprint on it. And as for the solder mask application. Instead of conformal coating. I think I will be okay as long as I coat it fully and protect against the liquid metal. Console will be sitting horizontal anyway. What you think?

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

So I think my stencil for the southbridge chip got lost. Has not moved since June 16th from last location. Just to be sure I did some further troubleshooting while i wait. Now i just have a single beep without making any changes. Due to that fact and having to wait. I pulled the APU sticker up and found liquid metal bridging a cap. I have cleaned the APU and around it. But i have three questions. How would the APU get this diced up on the surface? Will this effect the chip? And last but not least.. Can i use solder mask to coat the area around the APU, or should I use conformal coating? Anyone else coated around their APU?
