I am working on replacing the power supply and amplifier (big burn marks and lots of parts burnt up) in a XRs. A copy of the power supply schematic would be great.Comment

I am searching for Schematic and/or Boardview for Lenovo T14s Gen4, Board: KT4D5 NM-F221
This one is with Nuvoton NPCX997KAABX EC.
I was only able to locate one for a Version with MEC1723 Chip, but this is not the one I need.
I would buy it, if I knew a site selling it, but I just can´t find it.03-24-2025, 08:33 AM -

Hello.
I'm a self-employed mechanic/machinist. I'm attempting to fix my friend's Mustang dynamometer. He replaced the power supply but installed too new of a unit, which I discovered had no -5 volt supply. After installing the correct supply, this rectified the problem we were having with the load cell. But I'm still getting no speed output on the monitor screen.
I've checked the hall effect sensor and I am getting the signal to the daughterboard. I traced the signal through three processors in the lower daughterboard. I can see the signal at the input to the upper...08-15-2022, 03:52 PM -

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...
