PS4 Pro No Button Sound No Power Southbridge CXD90042GG Replacement

[@mohamedgothany240]

Guys this guy is the man! He's super friendly and honest. A great person to work with. With so much skill and communication I would 100% send my console in for repair. He'll make It right no matter what!

[@MrSodium271]

Recently I replaced the small black transistor(is it?) next to that southbridge. My console doesnt start sometimes and sometimes it does, is this southbridge problem?

[@ceejay_gaming9636]

Sir I have a PS4 FAT and when I press the power button I only get one beep but the system doesn’t come on, I also checked the PSU and it’s absolutely fine

[@AlphaBravoTech]

Maybe it's the southbridge. Maybe its the APU. Maybe it's something else. Hard to know for sure without properly testing it.

[@hamishussen1589]

What is the name of your pre heating machine

[@DjSerolmp]

Can a bad Southbridge cause a blod? I also have a ram chip that won't heat up. Ps4 currently has a blod flashing

[@LuFastNinja]

My power supply is fine, power button is fine, but I get no lights and only response is 3 beeps from eject button when there is a disk in. 1 beep when there is no disk. Disk will not feed automatically, and no response with controller plugged in. Does this sound like a southbridge issue?

[@LuFastNinja]

Also, did you test the PSU while plugged in?

Where you buy that chip? Can you help get a link for all chips for ps4? Thank you

Hello, I have here a adp300cr and when testing I didn´t have the 12v like in 6:50 minute, has at 0 all the time. How can I repare it?

[@AlphaBravoTech]

Hi Ruthless. I have a couple of other videos showing how to troubleshoot these power supplies. There's a lot that can be wrong with them though. If my other videos don't help you I would recommend to just buy a new PSU so that you can get back to gaming!! Sending it in to us is also an option. Thanks for watching! :)

Any advice for a ps4 pro that won’t turn on at all after a power surge?

[@Fox9582]

There was a power outage so my PS4 Pro stills turn on but the USB ports don’t work any more. Could this chip be the problem too or another driver?

[@justinl4060]

Hmmm my cuh-7215b has the CXD90046GG in it no power after a 5v connector repair.

[@AlphaBravoTech]

Connector ripped from the board of the PSU? Maybe it wasn't soldered back on to the PSU correctly. Maybe the PSU is just bad? A trained professional should verify the PSU is fully functional. Or if you can borrow a known good one from friend and test your console with that, that would be good too.

[@justinl4060]

@@AlphaBravoTech Ripped from the motherboard. PSU is good as I tested with known good system.

[@justinl4060]

I’m fixing a hack job repair that did have a blown PSU when their wires seemed to have grounded themselves.

[@AlphaBravoTech]

10-4. Well it could be your 46GG but if it was a HACK JOB repair and they even ripped a connector off of the motherboard, I would first assume damage on the motherboard. Inspect it very closely for damage. I've seen hack job repairs like this where they ripped a connector off and super glued it back to the board and make it look really good, like there was no issue. Then upon further inspection I realized a connector was actually ripped off of the board a needed rework. I would look closely for missing or damaged components and connecters before I went after the Southbridge.

[@DownUnder43]

Man I got a short on a different spot from the Ares you showed us. However close by towards the right side not directly under the southbridge. Under the southbridge everything is fine I also checked the IC chip and caps near by also good however the short is affecting 4 small Caps. I wonder how can I get some help to pin point what to order.

[@arthurcuesta6041]

Did you find an answer? I think I've got the same problem.

[@spearsc49]

I trying to test one but What measurement of voltage are you using to test it. Not sure what setting to set my multimeter to to read the voltage

[@AlphaBravoTech]

I was using continuity mode (beep mode) on the meter to see if any of those caps had a short tp ground. I hope that helps.

[@rileyandiggy3608]

Can I put thermal pads on this chip would it last longer or will it cause it to shorten its life

[@PiotrJareckiOfficial]

Hey, did you find somewhere answer for that? I am considering same thing since I saw that in slim model SCEI chip is connected to shield by thermalpad and aluminum little heatsink. SCEI chip gets really hot and in pro model it is hidden under shield where is little to no air circulation.

[@Jodasmp3]

Excelente trabajo. Podrias decirme que temperaturas usaste en ambas herramientas como asi el flujo de aire para desoldar y soldar? gracias

[@EdwDS]

ponelo a 350 o 400 para desoldar y soldar pero antes hacele un pre calentado si no tenes pre calentador calenta la parte de abajo a 200 por 1 min o menos y luego 350 o 400 arriba para retirar y para colocar lo mismo .. si le podes poner esferas nuevas antes de instalar mejor ya que las que trae tardan mas en fundir salu2s

I’m trying to repair my ps4 fat that doesn’t turn on due to a lightning (I think)... the power supply works, I tested components of the motherboard and a lot of smd capacitors in the front and the back too are shorted. How do I know which chip shorts all the capacitors? I’m I newbie and I really need help, thanks you for the help❤️

[@dean_ferguson2825]

I had Blue Light of Death. I sent it in and the person did a reflow on APU chips and reworked on Southbridge. The problem was not found and doesn't work. What do you advise me to do. Thank you

[@AlphaBravoTech]

It's better to do a reball than a reflow for a BLOD issue. I can take a look at it if you want to send it in. I have all necessary tools and equipment to do a proper reball. Hopefully the prior repair attempt didn't cause irreversible damage to the APU or any other components but there's only one way to find out! 😎👍

[@AlphaBravoTech]

Check measurements on the board with multi meter. Check for shorts. Also, where did you get your replacement southbridge? It needs to be from a trusted source. There are fakes out there. Did you possibly knock any component off of the board like I did in this video?

[@thetechgurulouies9952]

Hey great video and yeah it seems like the next gen of consoles got issues with southbridge chips going bad and having apu issues because of weak solderballs/cracked. Just have a question, can you tell if a ps4 with no power can be a power supply issue rather than a apu or southbridge causing it to not power on? Just planning on buying a no power for cheap to just replace the power supply if there was a way to tell even though it seems that you cant tell until you start to testing things

[@AlphaBravoTech]

Thanks. Cant really tell until you start testing things but with APU issues, the console will usually still turn on. PSU going bad is very common so if it hasn't been swapped out already, it is a high probability. Good luck and thanks for watching!

The first i would try is flashing the bios to see if that fixes the issue. But yes, it could also be Southbridge or similar type of fault, I think.

Hi Mickey. Thanks and thanks for watching! Most commonly, in my experience, that issue is caused by a cracked solder ball under the APU.

@@hidinfrombiden6251 how long does it stay on with the blue light and will it do the same thing immediately, over and over? If so, probably not an issue with the new power supply. But it could be.

[@hidinfrombiden6251]

@@AlphaBravoTech with my old power supply it's not doing anything at all. With the new power supply installed it will beep once and the blue light comes on for a split second. It does this over & over. I contacted the person who sold me the power supply and they said it sounds like a mother board issue. Just doesn't make sense to me that it's the mother board when I can swap power supplies and get different results lol. It's like the new power supply works, but for some reason it's not producing enough power to initiate start up. The day before yesterday I actually purchased another used PS4 Pro for $300 that's only about a year old. I bought it with the intentions of being able to swap parts between systems until I narrowed down the problem, so I wouldn't be just randomly throwing money at new parts, but the one I just bought is newer than my old one and the ribbon cable that plugs into the power supply from the board is shaped different. Other than that it's identical. After I noticed that I was going to just swap hard drives so I might get lucky and not have to reinstall all my games & stuff and even the hard drive has slight differences how it plugs into the board. So for now I'm in the process of having another power supply shipped to rule that out. I'm not sure what the issue is but I read somewhere online that people were having the beep once & light flash issue's and it ended up being the screws for the X clamp came loose or needed some washers put on the screws. I'm gonna check that on mine but I don't expect to find that problem lol. But that's about all I can think of, if I find anything out I will let you know. Thanks again for responding.

For the hot air I think it's alot to use more than 280 c and for the pre heater during desoldering temperature most be around 360 or 380 and for the solder process 280 same for the hot air and 340 on the preheater I'm proud that you use preheater because some people just go with hot air with no preheater I recommend everyone go to him

[@AlphaBravoTech]

Toqhy, thank you! Technique is better than exact temperatures, in my opinion. Knowing when solder is melted, knowing what temps it melts at, knowing how it acts when its melted. Knowing how everything works is key. Thank you for your comment.
