Re: MSI GE72 2QC Schematic plz
Sorry everyone for not english).
Пан, тут вельмi проста и робiцца усё без схемы i борда. Мультiметр для чаго? Становiшся на USB1 i глядiш якiя сiгналы адпавядаюць яму на FPS1. Потым вымяраеш гэтыя сiгналы с адключаным шлейфам.
Ну прасцей не бывае ). 99,9% вiнаваты будзе HUB ).Comment

Re: MSI GE72 2QC Schematic plz
At the beginning, I connected the ground probe and measured all the pins in turn. Only Pin DATE- has low impedance. This damage is on the motherboard but I don't know what could be damaged. is the bridge or is there a system in front of the bridge that protects the bridge has been damaged.Comment

Re: MSI GE72 2QC Schematic plz
Just change the bridge. What did you bind to this port? Are the others working for you? If yes, then leave him alone.Comment

Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:

Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this... -
Hi guys, I'm working on a MSI Ventus RTX 4080 16G. The GPU has 12v, 5v, however what I assume is the 1.8v rail has 1.1v and what I assume to be PEX is 0v. As you may have guessed already there is no Vmem and no Vcore.
I have looked around in related forum posts for a schematic so Much appreciated if anyone can share a Broadview schematic.
Thanks.07-15-2025, 11:15 AM -
Had one of these come in for repair with a blown battery and a WiFi issue, battery has been replaced with genuine battery (twice) and won't take a charge works fine on AC, WiFi issue gone away. Looking for a schematic so I can trace the charger circuit UM562F is only one I can find, this is the 562AI model.Had a unit come in for repair — 562AI model — with a blown battery and WiFi issue. WiFi fault has cleared, but battery won’t charge despite replacing it twice with genuine parts. Device operates fine on AC power. Suspect charger circuit fault.
