if you find let me know i need as well . -
Anyone found it?? I have a problem with this model, 3v line shorted, chip was damaged, I replaced sy8371b and kb9542q, flashed KBC and laptop works but it turns off backlight randomly and enters suspension, I have keyboard unplugged. I cannot locate lid switch circuit or any circuit without schematics or KBC pinout, I suspect maybe this controller I ordered in AliExpress is faulty but it costed around 20 USD π. I need to be sureComment

I was going to update what I found, now I see your post and evidently there is something weird about that fuse or little inductance, I traced line from little PCB where magnetic lid switch component is located, and it lead me to this component that had weird resistance readings, I changed it for a 0 ohm resistor because it feeded the 3v line for the lid switch, also the lid switch was behaving erratically so I also replaced it, laptop is working perfect now, it's been a hed ache fixing this without any similar schematics, thanks to all in this great community that helped me identifying some components.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. -
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 β 562AI model β with a blown battery and WiFi issue. WiFi fault has cleared, but battery wonβt charge despite replacing it twice with genuine parts. Device operates fine on AC power. Suspect charger circuit fault. Only schematic Iβve found so far is for...06-26-2025, 02:41 PM -
