Need help finding replacement cap for MSI x670-P WiFi

Today, 01:29 PM

I found the schematic for my board and the capacitors I need on it. They are the same part "0.1u16x SHAPE C0402" capacitor. Trying to find replacements online, not sure what to search. Searching 0.1u16x doesn't show any results of a part I can buy.

Edit-
Ok, I think I found the part. GRM155R71C104KA88D should work. I just ordered a reel. hopefully I can get them soldered in correctly.

Help identifying AMCH073 regulator or finding a compatible replacement

by taurtnt

Hi everyone,
I’m trying to identify a step-down regulator marked AMCH073. It’s used on the PEX power rail of a graphics card. I can’t find any datasheet or info online.
Here’s what I’ve observed:
• It has a QFN-16 footprint, similar to NB670.
• Pins 1, 2, 15, 16 are connected together and go to the inductor, so likely SW (switch node).
• Pin 9 is connected to GND, which doesn’t match NB670 (where pin 9 is SW).
• Pin 8 also seems to be tied to the same GND plane.
• The chip only says AMCH073, no manufacturer logo or other markings....

Msi pro x670p wifi schematic

by Rass

Hi,
I have an MSI Pro X670p Wi-Fi. When I boot directly with the CPU and memory, the red CPU LED and orange DRAM LED light up.
I tried updating the BIOS with QFlash from USB, and there's a signal from pin 2. I checked all voltages and they're OK, including coils, chipset, BIOS, etc. I checked the pins between the CPU and RAM.
I've also tried swapping the CPU for another one that's working in my personal PC and moving memory to different slots.
If anyone has any ideas or suggestions, I'm at a standstill...
If possible and if someone has a schematic it would also be...

Finding proper replacement rectifier

by unimatrix93

Hello everyone,

I'm trying to fix up my battery charger. Where I found a dead schottky rectifier.

This is the dead component PTR30L120CTF:
PTR30L120CTF datasheet(1/7 Pages) PFC | 30A 120V HPTR Schottky Rectifier (alldatasheet.com)

And I have a spare 30CPQ150:
30CPQ150 datasheet(1/5 Pages) IRF | SCHOTTKY RECTIFIER (alldatasheet.com)

Can I use this diode as a replacement or if not, can you recommend me a proper replacement?
I cannot find the exact unit anywhere besides aliexpress and such.

Thank you guys!

M557-G0 no WiFi/Bt no WIFIVendor file?

by howardc64
Thanks to Diah, got M557-G0 LCD panel buffer board repaired and running ( link ) Next challenge is no WiFi/Bt despite module on the main board and getting 3.3v supply (3.45v measured)
- TV Menu shows Network Access Point option (enet unplugged) but menu can't select that entry
- Service Menu shows many Bt/Wifi info missing
- Vizio app shows no WIFIVendor file
Prior owner used enet and said turned off wifi somehow. It seems system config info for wifi might be missing. Anyone experienced this before?
- Tried countless enet unplug (user manual said need to unplug enet to get to wifi menu), factory
