Hello bro, I wanted to know if you could give me the schematic of the b550m pro vdh wifi that you showed in the publication. I have the same error and I don't know how to identify the cms.

Sorry that i not described what i do on a board, i round with red components that i solder...

Hello there am interest about electronics but total noob about mesurment and i think i don't have right instrument...i was try to copy to put simular components from other donation MSI bord z690 and coponents look simular and i have on cople of places messing and on one place ripped components...would i be worry to put cpu and ram in this bord, before bord just try to boot constantly looping...any suggestions or advice how to chek components?

Hello. Could you please tell me a programm name?

Re: Msi B550M PRO-VDH Identified Missing Components

Checked on this chip what leg is connected to resistor pad and this lock like pin2 sense and in block diagram I see one with 10kohm 1% resistor this equal to my results from multimeter.


I make close up oh chip connected to capacitor pad

[hola you]

hi! i have the same problem that rabit has. but, i wanna know what is the value for the resistor below the IC3339A. someone knows?

Hello friends, I know that it has been a long time since the last response, but if someone could help me, I have the same motherboard and I bought the computer second-hand, I disassembled it to clean it and I think that when I disassembled those components, my tracks are in good condition. condition but in my opinion a resistor and a capacitor are missing in the first photo a black resistor and in the second photo a brown ceramic capacitor the problem is that I don't know the values to be able to buy them on Ali express, if someone could tell me what components I should buy, I have been testing with components from a laptop motherboard and the computer turns on but restarts in a short time and in stress tests, I hope you can help me. Greetings, thank you and sorry for my language, I am Spanish.

It - QH2 (cmkt3904).

Thanks for that. I checked that against the schematic and that is hotplug detection for the HDMI, I think it's unlikely that that is where my problem lies with this board as I am stuck with the CPU LED lit during boot. I'll keep looking to see if I can find where the issue lies.

Re: Msi B550M PRO-VDH Identified Missing Components

I welcome everyone, help me select the torn off elements on the board, under load there is an immediate reboot.
interested in elements under the number 1, 2, 3, 4

1 - 10 mFx6.3v
2 - 93.1 Om 1%
3,4 - 0.1 mFx16v

Re: Msi B550M PRO-VDH Identified Missing Components

Hello, Thanks in advance, I have a version of this board. MS-7C95 Ver:1.4
I too have a missing component that I can just barely see on the OP's post but the component marking is not sufficiently clear for me to make it out.
If you have this board can you check the component marking of the part in the location I have circled in my pics?
My board powers up but the CPU light stays lit without moving on to detect anything else

Having some problem. Reading thread helps me to identify missing smd's. Thanks a lot.

Re: Msi B550M PRO-VDH Identified Missing Components

I am pretty noob to the game so not sure if it's possible to identify these missing components from the schematic. I hope it helps.

woo amazing

Re: Msi B550M PRO-VDH Identified Missing Components

My flux is some chine cheap paste staff my solders splatters everywhere , I have hot air but not much experience with.
93ohm change to 53ohm but this can be due repairing broken trace.
also 10k ohm show 9.6k but testing now under stress test Furmark dGPU Rx 470 + CPUz stress test for CPU and is stable, previous owner have instant crash when stress dGPU Rx 5700xt

I ordered some PVB-60 Varnish from AG Chemia because was cheaper than solder-mask

Re: Msi B550M PRO-VDH Identified Missing Components

To cover the best solution is liquid soldermask (polish: soldermaska - easy to buy) you can paint it, and then harden with UV light. It also can act as kind of additional protective glue and is non-conductive. Apply only thin layers at one time, otherwise the UV light may not harden the liquid which is deeper beneeth the surface. Apply 2-3 layers to make is robust. You can use any type of UV light source, the stronger the better (but do not expose your eyes to UV light !!!!), so the hardening time will be lower. Even exposing to sunlight can harden this after a long time. The soldering looks not good but will most probably do its job, you should use more or better flux, maybe temperature is too high. Hotair gun would be better, but for one repair does not make sense to buy one. Also it is more difficult to use hotair gun, you need some practise to do it right, in order not to blow out the parts or overheat and destroy the PCB. Check the resistance of the resistor after soldering, it might happen that too long soldering or bad flux will decalibrate them, they are sensitive to chemical and temperature influence.

Re: Msi B550M PRO-VDH Identified Missing Components

Sure.

After my fix board booting to bios I check full load stability tomorrow.
And buy something to cover exposed traces.



Once more thanks.

Re: Msi B550M PRO-VDH Identified Missing Components

lol my 250mW resistor are so large that I not see pads, time to buy smaller one ;0
Capacitor soldered with coper wires, my work results do not look neat at all, my soldering skills are not top notch

Re: Msi B550M PRO-VDH Identified Missing Components

you can get grab another capacitor from another board . but same size and colour. the capacitor should be fine. its your copper thread broken and not connected. even if you dun fix the cap, it will still works.
