need schematic or boardview for MSI katana GF66 (MS-15811)

[tronitas46]

hi! I'm looking for a schematic or boardview for a MSI katana GF66 (i7-11800H and RTX 3060) board is a MS-15811 ver 2.1 if someone have it I'll be very grateful! though I don't have much hope since I did a lot of research, checked all the websites that I know of and I didn't find it, even someone on vinafix asked for it 6 months ago and he got answered that it was currently unavailable, but I'm still asking! we never know, thanks!!

Me too: I have a board with a burnt cap and what seems to be a voltage regulator? I would be glad if anyone can help me identify them so I can source replacements...

hi! from the picture your PCB looks damaged. was the chip blown? also from what I gathered it looks like a vrm used for 1.8v rail (seems to be connected to the bios chip which is 1.8v, alongside other things) but it's hard to measure since this rail is shorted to ground on my motherboard (no idea if it's normal like the vcore) either way I have no idea what the chip is exactly but at least I can provide some pictures of my undamaged motherboard

I too have a burnt chip, what seems to be a SOT23-5 (not 100% sure). It is labeled as 5AG1R but I cannot find the exact chip. I have been researching but nothing so far. Does anyone know where I can find this part or have an interchangeable part number? The chip is located in the area of the aux, usb and usb-c port.

a bit late, but it looks like it could be a monolithic MP2147 as the pinout, package, size and marking match what I have on my board, that said though from the picture you sent, the PCB looks damaged and would need to be repaired!

thank you very much! this will definitely help identify parts

The backstory is simple – the owner (that is, me) isn't exactly friends with common sense, and decided to remove the battery connector by prying it with a flathead screwdriver. Naturally, it slipped, short-circuiting the contacts of the black and blue wires from the battery. The motherboard stopped working... Nearby, a transistor with the marking MMo TD burned out, so I found the same one on a USB board and temporarily soldered it from there. However, the motherboard still doesn't turn on, which means it short-circuited something else. Any ideas where the blue wire could have shorted to the battery ground? I don't really understand complex circuits.

It is an ALHN 023 but i cant find it anywhere, can sombody help me out?

Yo también: tengo una placa con un capacitor quemado y lo que parece ser un regulador de voltaje. Me gustaría que alguien me ayude a identificarlos para poder conseguir repuestos...

Hi, did you manage to find out the value of that burnt cap??, thanks in advance
