The coin battery - this reminded me once I got a laptop that literally had a COIN instead of battery stuck into it. Laptop was dead (water damage), but at least I got 10 cents.
All respect. Compared to other techies, this man proves that he does a special job. I am a simple subscriber of this channel. The man is fair play. I've been watching this channel for a while and I'm impressed. Succes. I'm from Romania and bravo to the people who are able to provide this information.
[4:27] Wow, what a journey! Seeing you bring that motherboard back to life after all those challenges was super satisfying. Your knowledge and troubleshooting skills are truly impressive. Keep up the great work!
Nice save. I usually strengthen and repair high-performance rails with copper braid. For low power, I prefer to use copper tape. It is easier to cut and takes up less space under the mosfet component. I personally use the thermal camera with an extender, so I can place the tablet in a fixed place and move the camera around. As I do with my endoscope camera.
I am trying to get my thermal camera connected with my PC but i am having issues with the software and i am already in contact with their support and hope to be able to deliver better views with my thermal camera!
Need to check that 12v cpu power resistance in the future. The boards VRM is anemic to begin with. Pretty sure a 16 core would be VRM thermal throttled in a stress test.
Liebe den Kanal, habe eine Menge defekter Mainboards, und wenn man im Internet sonst nach "Reparaturanleitungen" sucht, findet man immer Foreneinträge "Dein Mainboard scheint defekt zu sein, kauf Dir nen Neues". Dabei sind es ja oft nur Kleinigkeiten die kaputt gehen, aber so gut wie niemand kann einen da weiterhelfen. Viel gelernt durch diesen Channel, Danke!
Es befasst sich kaum jemand damit, da es finanziell keinen Sinn macht! Das wissen und Erfahrung die man braucht ist an anderen Stellen einfach besser investiert, wenn man den Finanziellen Aspekt im Kopf hat. Ich mache das hier ja nur wegen dem Spaß an der Freude!
Why is it insane that a "70A P-channel MOSFET just burned trough"?. It burns because of power dissipation. In a short circuit situation the full 12V is dropped across the MOSFET. Even if it conducts only a single Amp that will dissipate 12 Watt in the MOSFET which is orders of magnitude beyond what a D2PAK can handle.
Thanks. It was an interesting video. If I'm not mistaken, after repairing the phase when you tested. You did not resolder the capacitor that you removed.
Thank you! It defenetly wasnt killed by that! The 3.3V from the battery has no way into the VRM section and also it supply so little current, it would be able to kill a mosfet!
As far as i know basicly every standard ATX power supply does that, but my PICO adapter doesnt do that! The server PSU that i use also has a protection, but it doesnt trigger because there is a mosfet in between from the pico adapter! And yet again i will ask, when will you do another "not repairing" motherboards! I really enjoyed watching your videos!
The phase probably got hot because you did not put the big aluminium elco back. Much more voltage variance due to that, resulting in much more switching and thus more heat.
That takes skill. There was this time my father tried adding ram to his computer and he somehow managed to squeeze it in the wrong way without breaking it a true master. FYI It doesn't take long to fry a CPU with no heatsink on it. Do you think the seller even checked it?
Might be, but i really cant tell why, with having the passive components checked and replaced the whole phase! So only the PWM controller left if anything!
I hate having to ask I got msi B550m pro - VHD (non wifi) motherboard a very small 2-3 chip has bubbled up (might be for usb ports) been trying to work out what the part is so I can get it and see if that can bring the board back to life
Hey Mainboard Medic, vielleicht kannst Du mir helfen. Ich habe ein Problem mit einem alten X58 Board. Ein Symptom ist, dass wenn ich die Grafikkarte in den PCIe stecke, dass sie nichts macht. Nicht einmal die Lüfter drehen. Die Karte funktioniert definitiv. Ich habe auch 12V und 3,3V am PCIe. Nun weiß ich nicht, was die Karte noch braucht, um sich zu drehen, ich dachte, eine bloße Versorgung mit Strom würde reichen. Ist der IOH tot oder fällt Dir vielleicht noch eine andere Fehlerquelle ein. Ich sehe das Problem zum ersten Mal. Grüße
Servus, ich habe aktuell eine ähnliches Situation bei der ich bei einem Board nicht weiter komme, dass bei einer VGA LED hängen bleibt. Aktuell nachschaut habe ich folgende Sachen: PCIE reset wird runter genommen PCIE lanes zum prozessor sind gut 12 v und 3.3V gechecked Mal einen mining riser dafür verwendet andere karten und andere slots verwendet alles bis jetzt nichts gebracht! Als nächstes müsste ich mal clock und data für den pcie slot testen! Mehr habe ich selbst aktuell leider nicht in peto!
Hey there, that is quiet new, so sadly no! Asrock Boardviews are also way harder to come by! Ive only found a pg lighntning D4, but its behind a pay wall!
@@MainboardMedic aww what a shame. But thank you anyway! I just replaced a damaged socket on that MB. Afterwards I was done and the MB cooled down I removed the kapton tapes everywhere. I also put some on the back of the MB. Looks like that was a giant mistake, since the tape rolled up because of the heat and "ripped" all the capacitors below the socket (backside of the MB) off during the soldering process. Now I wanted to repair that mess but I really have no idea where to put which capacitor lmao
Have you ever had a situation when motherboard boots only if you resit the CPU? MB boots and when I turn off I can't boot it again. Then I have to remove CPU, turn on and off mb, put in CPU and then I am able to boot to bios. And again same process, boot, no power, resit, boot and so on. B450 A PRO MAX
I detected that VDDP is missing with CPU, without CPU it's fine. What do you think, damaged socket? CPU_VDDP_S5 is 0.9 V but CPU_VDDP_EN is missing too with CPU in socket.
@@miosz8531 That exactly what i wanted to mention, everytime someone has a problem similar to that on AM4 it always had to do something with VDDP! I had it that on the EN line there were dead mosfets! You would need to check if the EN signal is still there after one bootup and you might be able to force the EN on and get the VDDP to run!
hello , i have msi A320M PRO-VD/S WITH WIRED PROBLEM ? if i leave the board for 10 or more off when plug it to power supply i can get 0.8 on all phase vcore but if i install cpu in i get 0v on phases even if i remove the cpu still 0 v i need to leave it turned off for another 10 days to get 0.8v on vcore phasses again , what could be board version 1.1
You replaced what was visually broken and nothing you did to this worthless motherboard was scientific. This motherboard shouldn't be used and needs to be put in the trash.
I really do that, dont i! It exspecially got worse because i was sick while recording the video! I will try to think off that the next time i will record a video!

Man I was looking for a motherboard repair channel for so long. Só Good to finally find one. ❤
[4:27] Wow, what a journey! Seeing you bring that motherboard back to life after all those challenges was super satisfying. Your knowledge and troubleshooting skills are truly impressive. Keep up the great work!
So proud of you!
I am looking forward to see your next repair videos!
Simply Great repair!!! Nice vid, thanks.
Very nice fix on both 👍
You can use isopropyl alcohol to remove hotglue. Less messy than hot air
Keep up the good work
заморочился ты конечно=)
интересно ремонт на грани фола)
спасибо лайк тебе

Well its also only a B450 board and a cheap one at that!
Glad i went for th B550 series of MSI, this boards VRM already looks weak.
man you are so good I wish I knew all that

"I love the smell of burning components in the afternoon!"
When you buy a board but get a hot tamale instead. That's a lot of Magic Pixie Smoke escaping!

Thanks. It was an interesting video. If I'm not mistaken, after repairing the phase when you tested. You did not resolder the capacitor that you removed.
Thanks for the feedback! I did resolder it, when puting the heatsink back on there, which makes it hard to see!
soo impressive given the state of the trace under the mosfet. real question is was it killed by the cmos battery being fitted upside down?
Thank you! It defenetly wasnt killed by that! The 3.3V from the battery has no way into the VRM section and also it supply so little current, it would be able to kill a mosfet!
@MainboardMedic thinking bout it probably won't do anything apart not being able to save bios settings giving out negative voltage.
First ryzen board i bought. I remember the VRM being terrible
very strong german accent.. yeees jaas
yeeeeeees, it exspecially gets worse, when i am sick like in this video!
The owner must have a ATX PS with short circuit protection, ie, you need to unplug it from the wall to reset it.
As far as i know basicly every standard ATX power supply does that, but my PICO adapter doesnt do that! The server PSU that i use also has a protection, but it doesnt trigger because there is a mosfet in between from the pico adapter!
And yet again i will ask, when will you do another "not repairing" motherboards! I really enjoyed watching your videos!
The phase probably got hot because you did not put the big aluminium elco back. Much more voltage variance due to that, resulting in much more switching and thus more heat.
When stress testing, the cap was back in there! Did that just before puting the heatsink back on there!
That takes skill. There was this time my father tried adding ram to his computer and he somehow managed to squeeze it in the wrong way without breaking it a true master. FYI It doesn't take long to fry a CPU with no heatsink on it. Do you think the seller even checked it?
That phase heating up more than the others may have caused the original fault?
Might be, but i really cant tell why, with having the passive components checked and replaced the whole phase! So only the PWM controller left if anything!
I had the exact same board and went up in smoke and blew a powersupply that board was crap... never thought MSI could make bad boards like that
bext time current limit it. Would have not damaged the boared as much.
The pico adapter is connected to a server PSU that cannot be current limited! I will be putting a fuse on that 12V line next time!
What temperature are you setting your heat gun to to desolder those SMD components?
For VRM and thicker boards i go around 400C and with smaller passive components i go for around 370-380C!
@@MainboardMedic Thank you! If I wanted to send to you an AM5 x670e board how would I do that?
@@ja.935g67 Sending me an email regarding that linked in my description!

Hey i gladly help! Sent me an image on my email and we will find it!
Put fuse on the adaptor?
Puting an inline fuse with the 12V is a great idea! I should get around to do that!
How am I not surprised it was one of the mosfets not covered by the heatsink that got unhappy?
Actually that one is covered with the heatsink! The thermal pad touching it even got burned into it! But the cooler is very small!
@@MainboardMedic when it blew, it looked like the one that is sticking out from underneath.
and this is why you have a current limit set on you power supply.
Well i am using a server PSU, which you cannot current limit! But i will be adding fuse in there in the future!
are you german bro? love your videos
Yes i am!

Have you tried a different power supply?
Those vrms need FANS
No they don't.
@BenState I mean, they could use one after they let out the magic smoke, just to clear out the room.

Hey there i do not charge for my repairs, because i do this in my free time!
no current protection on that pico adapter..... garbage
Jep exactly that! I did not know that before, but now i do! Every other ATX power supply wouldnt have done that!
can u share some board views?
Contact me via email regarding that!
WELL YOU JUST FRIED THE cpu TO
Nope, it booted just fine after that in that mainboard!
It's an MSI product, of *COURSE* it's broken.
hey hallo, n deutscher macht englische videos???
ok
Sachen gibts, die gibts gar nicht!
You replaced what was visually broken and nothing you did to this worthless motherboard was scientific. This motherboard shouldn't be used and needs to be put in the trash.
Would you midn explaining your argument further? Why this wasnt scientific and why the board needs to be trashed?
Please don’t fall into the American tap SODER as the word does have an L in English and is pronounced soLder not SODER
