    APC UPS SURT10000RMXLi defective

    I have a defective UPS SURT10000RMXLi.
    Some components exploded and some just not working.
    I have 2 optocouplers A3131 defective and I don't know if there is replacement for them and I don't have datasheet for them. I found 2 possible replacements HCNW3120 and ACNW3130 but I don't know if one of this is OK to replace the defective A3131 because I don't have the datasheet for A3131.

    Thank You.

      Help figuring out the resistance of this exploded resistor. gtx 1060 6gb inno3d compact
      by Bivolalbert


      Hello,I need help figuring out the resistance of this exploded resistor. I'm pretty sure it's the one labeled R37. I tried measuring it with a multimeter, but I got different values each time, probably because it's exploded. If you have a schematic, it would be really helpful!
      Its a gtx 1060 6gb inno3d compact, i you have schematic it would be very helpful....

      Repair Denon AVR-X2600h power amp SBL and SBR channel
      by re-atari
      A few weeks ago I bought a defective Denon AVR-X2600h receiver, wanted to use this one to find and fix a fault in my X2400h. This last part is already successfully done (turned out to be a defective TOP268VG in the X2400h's STBY PSU). So far so good.

      As I like a challenge, I now want to try to fix the X2600h. According to the serial nr. the receiver is built in june 2020. The seller wrote in his ad, that he had bought the receiver in a defective state, and wanted to fix it himself, but could not find the time to do so. The receiver would jump to DC protect mode when switched on...

      Lenovo Yoga Pro 9 14IRP8 - help identifying what exploded in the motherboard
      by iminusjk
      Hello everyone,
      I hope this finds you doing well.

      I need some help identifying what and how important is that exploded in my laptop's motherboard.
      Photos attached.

      My laptop is a 1 month old Lenovo Yoga Pro 9 14IRP8 (83BU), i9-13905H, RTX4070, 64 GB ram.
      It was in the charger, and I was excited to play FC24 for the first time, but when the loading screen came something exploded in the laptop and it shut down.
      It didn't turn on for about 30 seconds after that, but then it turned on and has been working seemingly perfectly (at least I didn't notice...

      NVidia bumpgate
      by piernov
      Just archiving everything related to bumpgate since most stuff has disappeared from Google. Maybe people will finally take the time to read some of it and stop shouting "reflow gpu" at every occasion but rather try to understand what the real issue is…
      Interesting parts about the failure analysis are "Why Nvidia's chips are defective" and "Why Nvidia's duff chips are due to shoddy engineering"


      May complete this post at a later date with more details.
      Basically issue is a combination of thermal dissipation of the chip with hotspot,...
