hi everyone. can anybody tell me what is PU26 and U43 in this mainboard, or please upload boardview if possible. thanks anyway

Read the BOM file, it lists all parts - https://www.badcaps.net/forum/troubl...07#post3536607

You are right. Considering that I have already found 3 defective integrated circuits, all powered by the 5V rail, and even 2 faulty Drmos, I really need a boardview to see what other components are powering this 5V rail. I can't find a schematic or a boardview anywhere. I have another question related to these drmos. I have QD9619A on my board and I would like to replace them with SIC651CD but I don't know if they are a good replacement. Thanks.

Hello friends I'm working on this MSI MS-16R81 V2.0 motherboard and I noticed that there is the U31 chip which shorts the +5 line. I removed it but I couldn't find its datasheet or the schematics of the card to replace the chip. Can anyone help me with the motherboard schematics , boardview or the chip datasheet? Thanks in advance.

From the BOM607 spreadsheet https://www.badcaps.net/forum/troubl...07#post3536607 ,it`s SLG5NT1757V

Hello all electronic technicians fellow mates ....

I have received parts from china and replaced damaged ones, and that chip BFCP is exactly MPS/MP1613GTL-Z so the BBBR is the same, i have received from china BBBN which is still the same chip.


For the record : the resistance values of my CPU SRMAQ:

1: 135 ohm
2-6: 4,23 ohm
7-8: 10,22 ohm

Are perfectly fine, and the CPU is ok and survived a short circuit caused by a user when he tried to do a maintenance...but the RTX / graphic card did not survive it and is dead

Does anyone know if there is a motherboard modification ( sometimes there is a need to replace resistors ) on schematic to force LCD to display image from integrated GPU/intel rather than from RTX...because that laptop is working perfectly fine but on external monitor ...inbuilt lcd stays black

Dear friends can You please check me if I am thinking correct, that those values on coils are ok ? :

The CPU is SRMAQ:

1: 135 ohm
2-6: 4,23 ohm
7-8: 10,22 ohm

Thanks to noname2024's help, I know that my processor is working and the values are as follows

noname2024 Please help. The marked places are vias, which are corroded by the liquid on the other side. I need to know what these signals are and where they lead to, so that I can eventually pull up a new line.

IC CONVERTOR,MPS/MP1613GTL-Z,SOT583-8pin,3A SYNCHRONOUS STEP-DOWN CONVERTER WITH SS & PG,HALOGEN FREE

So the BBBR, BBBJ is the same exact chip so as the a BFCP, and those three chips are MPS/MP1613GTL-Z ?

[noname2024]

BFCP ( PU29 ) It is similar to BBBJ ( PU18 ) chip and it is close to that chip on that board. - I've marked it with a yellow arrow on last picture

Hello dear all friends. Can anyone please tell me what is a IC chip PU29 on MS-16R81 VER:2.0 board it has BFCP marking on it ? I will be truly appreciated

post pictures of both sides of the IC

[Ali milan]

can someone share the schematic of this board 16r81 please ?
we need it urgently

[MattTheNoob]

Oh i see, does anyone have a boardview of this board? MS-16R81 VER:2.0

[SMDFlea]

How should i open the boardview ? I see it is in xls file , and my boardview program cant read it , im new to this , how could i fix it ?

It isn`t a boardview, it`s a BOM, Bill Of Materials. A list of all parts
