Msi B550M PRO-VDH Identified Missing Components

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

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

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

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

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

1 - 10 mFx6.3v

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.

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.

[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?

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

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?

[Zumimi]

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

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.
