    Mac Pro 2013 a1481

    Hey wonderful that you got the system booted .
    I came across this thread in the hopes to find a schematic for the a1481 , I believe they don't exist . Please correct me if I'm wrong. Also if you'd post them i'd be greatful .


    i have a Mac Pro 2013 a1481 with led 2 , 3, 5 remaining on and then the system tries to boot to s0 , with led 6, led 7 ie s0 and s4 turning on simultaneously and Turing off .
    I don't have a doner board nor schematics … hence trying to figure out where to start to probe . I've checked all connectors and cables which a seated and working fine .

    Also I don't have the WiFi and fan cable plugged in since the cable is currently broken and no SSD installed .Will it have an effect for the system boot ???
    I have only one 4gb Ram stick 1866mhz installed in slot 1.

    I can share images or video of the system if you'd like .

    thanks

          Mac Pro Late 2013 A1481 ISSUE
          by Stephen
          So the computer works minus a flaw with the HDMI port. LCDs get detected but they won't display. I plug the LCDS into the Thunderbolt port no issue. HDMI port doesn't seem to display. So I plugged in multiple monitors and used the HDMI port and it detects the display but won't give an image. One time it gave a grainy colorful distorted image which makes me wonder if it's a bad HDMI port or Gpu Board? Anyone have any ideas? I am leaning towards a Bad hdmi, or bad D300 GPU or maybe the top logic board? I have never seen this issue before and would like to fix it. Any suggestions would help. I believe...

          A1481 Late 2013 Mac Pro (Trash Can) Clean Bios needed
          by Stephen
          Can't seem to find it on here so sending a request. Did a search and nothing came up. We ordered 3 Bios chips for these Mac Pros (they have been installed with Monterey and we suspect it corrupted them firmware on the Machines) so we need to replace the bios with an older clean version to wipe it and update to Mojave.

          These are not EFI locked. I believe the firmware is corrupted and needs to be cleaned up.

          A1398 15” 2013 short when screen plugged in
          by bogosort
          Hello,

          I have a MacBook Pro 15” A1398 2013 that has no backlight, but I see an image when putting light through the logo. I noticed that when the screen is plugged in, I get a 300 ohms short (see image).

          When unplugged, the short is gone.

          Any idea?
