    Need help reading Schematic.

    Hi there

    Was wondering if anyone could point me in the right direction, Schematic "LA-5891p"

    Working on dead laptop or attempting to bring back to life.

    On reading the schematic everything makes sense until I reach this page 47, PU17 ISL6251, please see attachments.

    Getting stuck on pins

    1 VDD is this pin going to pin 15
    2 ACSET where does the X go or mean
    23 ACPRN where does the X go or mean

    Many thanks in advance, thank you.

      It seems those pins are not used. The usual AC function is done by the Vin Dectector on page 44.

          Help reading schematic voltages input/output
          by gjgib
          Hello, this might be embarassing since I consider it a dumb question but keeps me kinda stuck sometimes in my journey.

          I want to know if there is any post in this forum which explains my questions. A) When, where and how do I know when X voltage line is input or output. Example:


          I'm battling with this IC to understand it's voltages. It's from non-turning-on Lenovo Ideapad 3 15iil05 - NM-D461.

          I see some lines like +5VL / +5VALW / V9B+ / +3VALW being okay and some others like 1.8VALW / +0.6VS / +2.5V_DDR. I just know that some of them are bad or missing,...

          Schematic vs. Reality: Where Are the Resistors on My Sharp Clock Radio? Model FY-70CH
          by TinkerTron
          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:
          The schematic...

          Acer x163w Monitor PSU schematic
          by atunguyd
          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...

          MSI Ventus RTX 4080 16G Broadview schematic needed
          by Thetechdude
          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.

          Help reading this electrical schematic
          by Cornboats
          I'd like to make a motor speed controller on an ex brush universal washing machine motor.
          The motor runs for too fast so I'd like to reduce the revs down into the 10s. I've bought several motor controllers off Ebay/Amazon but the 240v version doesn't maintain the motor at low speed under load at constantrevs. The DC version I bought was good at low revs but I turned the unit on without turning the control potentiometer down first. This has blown something on the board and the fets/triacs aren't marked( Chinese) so I can't replace the obvious. I found this drawing on line and decided its...
