Where I get components sheme ou datasheet for supermicro Motherboards?

Nice video bro, how to make the connector for check Amp and Voltage

CPU debug sockets doesn't been a good thing for u?

Hi, where are you located, my Wife's B550 Pro4 died. It has only 70 Ohm between power and 3,3V which seems quite low, but idk how to find the defective component, no damage visible and nothing getting irregularly warm

i have b450f and similar am4 board have PCH resistance 17-25 ohm, working properly. please check that PCH line, if under 10 ohm it's very likely dead PCH.

Why you didn't replace the capacitor ?

When u mention the flux stinks bad, so what flux do u use regularly? ✌️👍

You can take-off the upper half of the CPU-socket to make a thorougly inspection of all solder-joints under the microscope.

Usually the off-board pre-programmed controllers are marked with a colored dot.

It's also important to remove the remaining flux.

Usually the Oszillator is used in a "free-running" mode, this means the Oszillator shall start oszillating by itself as soon as the voltage is applied.

on some other channel, cant remember which tho, or if it was same board, the SIO was dead and after replacing the board shined

Crazy! I still have it, with Windows. I can't find a way to use the microfone. You knows how to find win driver?

27:00 Would it be possible for you to share the picture/the source of the AM4 power sequence in the video description?

CPU socket replacements are not easy.

14:46 WinRAR - interesting. I've not installed WinRAR for about 20 years - 7zip having replaced it entirely.

I have same problems with Asus prime a320m-k r2.0

If a crystal "Oscillator" isn't outputting a wave form and it's getting it's required Voltages, The lil sh't needs to be replaced. Mind you 1st check if all capacitors supporting the sub circuit have not shorted.

Can you put an artificial signal to the PWM IC to get the VRM working. I was thinking a while back about all the checking AND gate transistors on a MB, and don't all 3 pins have to be high for an OK signal, ie, if pin 1 and 2 is high turn on pin 3. Like one high and the next low to turn on doesn't make sense. So you could check them quickly looking for 3 highs.

First, it's asus, second, it's amd, third the solution is to check the enables and signals from the schematic, it could be a component open or shorted, don't assume or take anything for granted, verify it and follow the scientific method.

Bin mir zu 100% sicher das du das Falsche Bios ausgewählt hast. bei 13:33 wählst du nen Z390 Bios aus.

When reflashing, I use a clamp, I remove the cpu and ram. If it fails usually it's because a cpu is installed. Ram rarely so.

The true value is the content and the learning you get out of these. If you fail to repair a board, you get a supply of spare parts from it which is very useful for future jobs. I suspect that repairs have been attempted on the majority of faulty mainboards you find in places like ebay, particularly if they come in lots. The everyday user with a board that has failed does not know which part is faulty and generally won't take the system apart to sell individual components. These are most often prebuilts. Such a user will throw it out, or send the system in for repairs. Some repair centers will do component-level work but more often they will swap the board for a working one. Bad boards may get sent or sold to a facility that does component-level work. Boards they can't fix may be resold individually or in lots. Unless you work in such a repair center, expect tons of boards with failed repairs.

Don't worry, I think each of us has failures in repairs but that's the only way we can learn. Thank you for the videos and good luck in the future.

Hey i really Like your videos and i tryed to repair a board alswall but unfortunatly without succes

Thats why you should deny previously repaired boards. The rabbit hole you get into (time) and the price of the board never make economical sense. Only thing you get out of it is more knowledge and share what you figured out.

oh no yet another video

I have a Ryzen 9 3900X with GPU PCIe 16X not working, and it also freeze if "Global C-State Control" and "Cool n Quiet" are enabled on BIOS. The cause of failure in my Ryzen CPU was a DisplayPort cable with Pin 20 enabled, that caused a shortage with the monitor giving voltage trough the Pin 20 directly to the GPU and CPU.

Hello master MOBO Yoda repair ninja !. Much respect for shared knowledge. Why not just change the socket ?

I have a C6H X370 with Q.Code 54 error. I believe that is same problem as your B450 Aorus board.

Nice work sir... Do you have Broadview and Schematic fo Asus ROG Strix B760-F?

I think I saw a missing capacitor in the middle of the lga socket on the right side 2 or 3 rows up from the bottom.. It looks like it was knocked off during the socket replacement. However it looks like a bad BGA Soldering attempt. Cheers!

Would heating up the PCH do any good?

Excellent job! Those drivers are really hard to remove without a preheater, especially when they fuse with the board :)

Weirdly enough that's the exact resistor i had issues on my board (same exactly board) 3-4 years ago right when i installed my GPU. Was lucky enough to just touch with my finger around that area and saw the rgb light up and manage to narrow it down and fix it(i do microsoldering so that was not an issue). Now that i see your video though i wonder if it was weak soldering from manufacturing and component just gave up when GPU was slotted in. (P.S that was my personal pc no a customers )

Great work bud, wish I could 2 thumbs up, I am learning from every video I watch much appreciated for sharing your knowledge

Vaseline maybe not flux lol, had one before like that. Stank.

Thank you!

I have a collection of boards that all have the same problem. They all don’t post. They all switch on, but will not turn off by switch. CPU doesn’t get warm. I’ve put them in my dead pch pile :(

hot tweezers are easer to remove the little bios chips no hot air needed !!!

Hy, I see that You know to program bios from diferent manufacturers. Could You consider to make a tutorial of: -downloading -converting -programing of a bios on diferent MBs?

If you look at northwestrepair he changes GPUs with a simple preheater and a hot air gun.

I have a question concerning the PCI-E tester starting at kzbin.info/www/bejne/b6vWnmScadV3pbs: On a working board should ALL LED's on the tester light up?

Damn, that uefitools program.. why didnt i knew that exists. I was using hexeditor and manually cutting out the not needed stuff lol. So i definitely learned something today! Thanks for that Hope u can swap sockets and maybe pch's some day man, then im sure u can just fix just about anything. Greetings from the netherlands

Seems like you need to rename to Mainboard Pathologist :) Never fun trying to fix another incompetent techs mess is it !

I think in the future if you see that the socket has been replaced and the board doesnt work i would check all the data lines first. i need to get these test aids for myself 👍👍

why would the bios chip have needed to be removed, surely they could have just flashed the bios insitu from the boards website

Do you ever repair a board worth repairing?

Where do you get your board view diagrams? And also the repair guide you showed in the video? Thank you for the great content!

I have a brand new old-stock gigabyte z170x board that tries to post with 4 long beeps when no RAM installed. With RAM installed I get no beeps and it turns off after 30 seconds then tries to boot again, in a loop. I tried clearing CMOS and forcing it to backup BIOS. No luck. Any suggestions about what to do or check would be appreciated…thanks!
