    JTC B-28 Cardmp3 player amplifier Schematic

    I'm trying to troubleshoot a JTC B-28 Cardmp3player amplifier which had a power supply failure. I've replaced the damaged str transistor with a 3wire power module and now it's powering up fine but it has very low and poor quality audio output.
    A schematic of this 12vDC/220vAC Power amplifier will be of great help.

      Roland SPA-120 Amplifier Tech Notes / SM / Schematic Source?
      by KeyResults
      Repairing a Roland SPA-120 amplifier, a solid-state early-mid 80's part of the Roland Rack. The PCB is Labled AP-124B. Was thinking lytics would resolve the nasty output on scope but all tested 100% for values, ESR, and leakage (very surprised!). Symptom is nasty wave form on both channels in Stereo mode, but clean in single channel mono (BTL) mode. The Output transistors test ok at room temp, but still could be faulty once heated up. Anyway, a schematic and some test point voltages would sure save some time. Thx!

      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. Only schematic I’ve found so far is for...
