It's a shame for this board. But please know that we benefit from your knowledge and experience so it's not a lot of work for nothing as I have read in other comments. Plus, your videos are satisfactory to watch. Thank you so much !
@@ToltecMerc Mine had no cracks but someone handled it before and apparently, injected voltage in the V-core rail (soldering traces in a coil). Wrong voltage quite probably.
So on the tiny caps around the HDMI encoder I've been watching you but when I try to solder one on the hot air blows it away every time lol. I guess I need a lot of practice but can I ask what temperature your air is set and what temp you have the soldering iron set at? Also what soldering tip you using, mine is small but you have one that has a tiny tip looks like it fits the smaller parts better. I really like your videos you are the best.
@@ToltecMercAn advance apology for my intrusion here: Why always in the corner? You are right; perhaps the perimeter contours are its weakness (manufacturing) and for the first time in that type of failure I had to look at the thermal camera again and it indicated [30 - 35] degrees Celsius, which then, for an APU, has a similar effect to Arizona desert sun at noon in the middle of summer...I'll have to pay more attention to the temperature when an APU is running hot On the other hand, when they mention "fall" of the MoBo, I always think wrong, that is, from the work table to the floor and checking the PCB the card does not show fractures to the naked eye although I think it can also be affected if only It slips from my hands while I hold it and falls even with a "light" bump on the work table... If the owner previously powered that mainboard with the fuse and resistor in the wrong positions, did that cause the APU to fail? Greetings.
(37:42) First time seeing you place two small spheres on each pad and how they merged so correctly to form the reballing on that Wi-Fi module. Interesting? Educational? Of course YES, with you sir we always learn something. Thank you very much for sharing. An affectionate greeting from Mexico.
Underneath that inductor that you were chasing around for the short, looked like a small solder bridge. Was the liquid metal causing the short on the crack of the APU die? Interesting video.
I have two Hakko FM-203 stations with various tips and hot tweezers. I also have a small nano pencil iron that I find a use a lot for almost everything except HDMI port anchors. I got it from AliExpress www.aliexpress.us/item/3256805070831963.html
Thanks for another great video - if it helps ease the pain of that lengthy diagnosis in any way, I have recently had three PS5's with exactly the same short on that cap and circuit, and all had failed APUs! Even though it was an impossible repair, it is great watch!
Thank you very much about inspiring us. So i have a question if there are not hdmi IC ps5 doesn't turn on,and if there are no blutooth module on the mainboard ps5 does not turn on too? Because ps5 can't connect to the Wi Fi,there are 3.3v then i removed module,there are one pad missing/cracked,tryed check ps5 without module and ps5 doesn't turn one,just one bip and error code 8081000 3 days past looking the board with confused head..
The APU is married to other components on the board. All would have to be changed together. Those parts are also married to a chip in the Blu-Ray drive. I have yet to attempt to remove a PS5 APU. I'm sure I will eventually but not yet. I don't have the proper tools. You need a BGA machine to do it safely and properly and good ones are very expensive. I just can't justify the cost of it.
@@ToltecMerc Thank you and Interesting, I thought it would have generated some sort of codes linked directly to the APU due to the obvious damaged you discovered but clearly not but just wishful thinking. The code system or algorithm would need to be much more sophisticated to pinpoint that kind of specific disgnosis. It's plausible and perhaps not impossible.
Can I ask what flux are you using,? Mine doesnt clean up quite as well must be just cheap flux that I have lol. I think you are the best I've seen keep it up.
This one was a little brain scratcher alright. Nice fault finding though. Cracked corner indicative of fall damage right? I do have 2 boards, one with hdmi ic isaue and another with ssd controller ic issue. But no matter how many times I try to replace them, they keep coming back up. I've got no idea where to begin. I want to revive them as they are on the lower firmware side. You wanna take a shot?
I think the crack in the corner comes from the internal short and the resulting heat but I really don't know. You can email me at toltecmerc@gmail.com to discuss the other boards.
South Bridge is just a common term used to describe a secondary microprocessor. It is a complete processor on its own but its job is to handle tasks that need to be done without using the power hungry APU. The South Bridge is active in standby mode and in this case handles getting the machine ready to turn on.
Hello Sir, thank you for showing all these repairs. I'm trying to get some practise with PS4s South Bridge reballing but I keep struggling with the manual placing of the balls on the chip. I even tried with a reballing station, but the stencil didn't align perfectly and the balls get stucks underneath it. Since I want to try the complete manual way, like you are doing in your videos, what is the name of the tool you are using to place and adjust the balls on the pads? And also to dispense the green uv mask.
That "tool" is just a needle mounted on a plastic handle. The handle was from some cheap dollar store dental cleaning tools. I removed what was originally mounted and mounted needles on the end. One is bent and one is straight. It is a very crude but effective tool that I seem to use all the time.
Thanks! Yeah I have already started on the second one and there are quite a few components missing. I will give it a shot anyway. I hope people enjoy the video even if I can't fix it.
@@ToltecMerc I know I do. They are very educational. I like how you go throw it at a slower pace so people can keep up with what’s going on. Keep up the good work.
Thanks for sharing your work and knowledge! Especially bench psu display, really helpfull. I’m actually trying to revive one of them… What is the maximum voltage an apu can support? I made a mistake and send 1.3 volts directly in the apu line for some seconds (consumption was about 1.3 amps, apu was a little warm) Thanks for all again, please continu sharing all this content
All that work and then the APU was as abused as the rest of the console… amazing job!
Thank you Tony! It is the sad reality of what we do!
Good videos, well explained and doesn't skip over the stuff most uploaders do
@@Eon-97 thank you. Glad you enjoyed it!

So true in what you said.
U are the best!, of all youtuber electronics repairs and diagnostics
Wow, that's very kind of you! I am having fun with these repairs and the videos. Hopefully, more to come!
I had one with the same issue last week!! Unbelievable.
Good video, as usual.
Thank you! I have seen 2 or 3 APUs with cracks in the corner.

That is a real shame, i guess it was dropped at some point, that seems to happen a lot with dropped ps5's
I wonder if it was a drop or if it just cracks from the heat from the internal failure. Why is it always in the corner?

Top repair. Awesome job. I wish you at list 100K subscribers! :)
Thank you! Maybe some day I can reach 100K and then retire and just make videos everyday!

Yes, I used two 0.6mm solder balls on each pad. It seems to work out well for me. Greetings from the US! Thanks for watching!
Nice troubleshooting and walkthrough sir. Keep up the great work!
Thank you! I do enjoy troubleshooting even if it doesn't always work out.
Hello and thank you for having me.
You are very welcome!
All that work, So close! Another donor board though. Thank You.
It was a lot of work. All for nothing. I wasn't expecting a bad APU when I started making the video. It happens!
welcome back hope you had a happy Easter great video as always
Thank you! Unfortunately, I had to work Easter. I had to be at work by 7:30 that morning. Thanks for stopping by.
Can’t catch ‘em all. Still great viewing. Thanks
Thanks! Yeah I can't fix them all and I want to show that. It's not always 100% fixes and pure profit.
Underneath that inductor that you were chasing around for the short, looked like a small solder bridge. Was the liquid metal causing the short on the crack of the APU die? Interesting video.
I think when the APUs fail, the internal heat build-up in that spot in the corner causes the crack. It's just a theory.
Great video, that reminds you to check APU first, before any repair
Absolutely! I need to at least glance at the APU. It would save a lot of work and heartache.
Hi just a question what soldering iron do you use please model number.
I have two Hakko FM-203 stations with various tips and hot tweezers. I also have a small nano pencil iron that I find a use a lot for almost everything except HDMI port anchors. I got it from AliExpress www.aliexpress.us/item/3256805070831963.html
Thanks for another great video - if it helps ease the pain of that lengthy diagnosis in any way, I have recently had three PS5's with exactly the same short on that cap and circuit, and all had failed APUs! Even though it was an impossible repair, it is great watch!
Thank you! Quite unfortunate but at least it was a donated console and not one I had paid $200 for.
Nice job! Are you going to try to swap apu? The board looks like a good candidate.
No. I just don't have the BGA equipment. Maybe I will try it someday but it's quite a bit of work.
Thank you very much about inspiring us.
So i have a question if there are not hdmi IC ps5 doesn't turn on,and if there are no blutooth module on the mainboard ps5 does not turn on too?
Because ps5 can't connect to the Wi Fi,there are 3.3v then i removed module,there are one pad missing/cracked,tryed check ps5 without module and ps5 doesn't turn one,just one bip and error code 8081000
3 days past looking the board with confused head..
I think if either the HDMI encoder IC or the BT/WIFI module are not communicating with the South Bridge, it will not start correctly.
Another question. Why can’t you replace APU????
The APU is married to other components on the board. All would have to be changed together. Those parts are also married to a chip in the Blu-Ray drive. I have yet to attempt to remove a PS5 APU. I'm sure I will eventually but not yet. I don't have the proper tools. You need a BGA machine to do it safely and properly and good ones are very expensive. I just can't justify the cost of it.
very nice,,, maybe get the apu on the donor board and installed there is that possible?
You would need to move several ICs over, not just the APU. I'm just not ready to do that.
Thank you for sharing. I am wondering could you have used UART for finding what kind of faults are registered in the console.
I did read the error codes with UART. I believe it was "General Power Failure"
@@ToltecMerc Thank you and Interesting, I thought it would have generated some sort of codes linked directly to the APU due to the obvious damaged you discovered but clearly not but just wishful thinking. The code system or algorithm would need to be much more sophisticated to pinpoint that kind of specific disgnosis. It's plausible and perhaps not impossible.
Nice work as always.
Thanks! I'm glad you enjoyed! I always appreciate the feedback!
Can I ask what flux are you using,? Mine doesnt clean up quite as well must be just cheap flux that I have lol. I think you are the best I've seen keep it up.
I use cheap Kingbo flux. Nothing special. Thanks for the visit!
Nothing like a cracked APU for upsetting the apple cart
Yeah it does ruin ones day. I wish I had noticed it sooner. I will be checking going forward!
This one was a little brain scratcher alright. Nice fault finding though. Cracked corner indicative of fall damage right?

What temperature are you using for the hot air? Great work!
I use 400C for most of my work. For things like HDMI ports and WiFi/BT modules, I use maximum heat(500C).
Another awesome job.
Can't save every ps5 , i hope the other ps5 can be saved.
Thanks again!
We gonna get a vid on the 2nd console? Fingers crossed better outcome.
Definitely! It may be a disaster as it is a parts donor. We shall see.
Everyone uses the term south bridge and north bridge. What exactly are they ??????
South Bridge is just a common term used to describe a secondary microprocessor. It is a complete processor on its own but its job is to handle tasks that need to be done without using the power hungry APU. The South Bridge is active in standby mode and in this case handles getting the machine ready to turn on.

Thank you! Are the needles a surgical hollow type or the ones used to sew?
@@spegggghy no. Just regular solid needles with a flattened head.
Great video as always. Any chance you can share the link to get the PS5 fuses.
I ordered from here: www.aliexpress.us/item/3256804733046898.html Every PS5 board I have seen uses a mixture of 2.5A or 5A fuses.
@@ToltecMerc thank you been looking everywhere for them much appreciated indeed
Good job. So close but so far. Maybe better luck on the other one he sent. Too bad he used it for parts.
Thanks! Yeah I have already started on the second one and there are quite a few components missing. I will give it a shot anyway. I hope people enjoy the video even if I can't fix it.
@@ToltecMerc I know I do. They are very educational. I like how you go throw it at a slower pace so people can keep up with what’s going on. Keep up the good work.
Has there ever been success replacing an APU?
I'm sure it can be done but I don't have the proper tools. I may try to do it the way I do PS4 APUs but I'm not sure if it will work.
Thanks for sharing your work and knowledge! Especially bench psu display, really helpfull.
I’m actually trying to revive one of them…

I honestly don’t know how much they can take but there is a good chance it still ok if you did not leave it applied for a long time.
@@ToltecMerc will send it to you in a possible future if you want to try a resurrection :)
Thanx master ❤️🇹🇷
