    Ps5 edm-033 bios and southbridge standby voltage


    Hi all,

    i need your help for understanding if there is an issue around my bios on edm-033 and around southbridge pin P16 and P17.

    I have removed my Southbridge and when I check standby voltage on the bios, I’ve got this value:
    • pin 1: 0,16v
    • Pin 8: 3,3v
    • Pin 7: 3,3v

    I think there is an issue between 3,3v line and cs pin, but I don’t know where.

    then this are the values on SB P17 and P16: 0,93v, But I have 3,3v on L17.

    Thanks for your help.

      Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
      by tvguy12012012120
      This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

      Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

      🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
      by macabook
      Hello everyone,

      I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
      🧩 Initial Issue
      • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
      • External display (HDMI) shows

      ASUS TP500LA BIOS request/repair/merge?
      by jbonavita
      Hi, my laptop wont boot at all
      With original bios no POST, only LED lights
      With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
      Some issues
      A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
      B- If updated from 500LN version 203 to 300, the battery stops being recognized

      Things I tried

      1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
