    isklst ver 1.0 need schematic or info U502

    Hi, today the sound stopped working in my Lenovo when I was repairing the amplifier connected to the headphone output and I shorted it. I'm looking for a circuit diagram or information about the integrated circuit that produces sound. Everything is in the picture.

        Probably an ALC233 https://linux-hardware.org/?probe=41f38e1f81&log=amixer .Not sure which motherboard it has

        The ISKLST1 6050A2817301-MB-A01 motherboard has an ALC233

            I bought ALC233, soldered it and I can confirm that it is this chip, the sound is back.

            Thanks to colleague SMFlea for the accurate identification of the integrated circuit.​

            Pozdrawiam.

              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.

              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.
