    RTX 2080 ti (Zotac - triple fan) - No video output / Vcore / Vmem missing

    Hi,
    I have an RTX 2080 ti (Zotac - triple fan) with no video output.
    So far I have measured the following:
    • PS_FBVDD_PH3_SW = 40 ohm to ground (Micron ICs) - Memory should be fine right?
    • 12V power rail present
    • 3.3V power rail present
    • 5V power rail present
    • 1.8V power rail present
    • Vcore power rail missing --> PS_NVVDD_VREF is present. (from uP9512P / U812)
    • Vmem power rail missing --> Not there because Vcore power rail is missing.

    Any idea? I have already tried to flash the BIOS chip (backup got created) - sadly no changes.

    • Version: 90.02.0B.00.C7
      AND
    • Version: 90.02.17.00.58


    Note: GPU chip is getting hot when PC get turned on - Won't be recognized by MATS.

    MATS result - command: ./mats -e


    command: ./mats -e 5 :less only says "standard input".

      Edit:

      Has anyone the boardview + schematics for the GPU mentioned above? I only have it from a MSI RTX 2080 ti.

                  Evga Gtx 1080 vmem but no vcore
                  by floodster1
                  I have an Evga 1080 for repair.
                  There was a short on the 12v and a burn hole in the bottom stage of the vcore.
                  I cleaned it out and the short is gone.
                  Iv checked all the resistance on the minor rails and there good.
                  Voltages are.
                  12v
                  3.3v
                  5v
                  1.8v
                  Vcore 0v
                  Vmem 1.3v
                  Pex 16mv
                  I thought you need to have vcore or pex before vmem would turn on so it leaves me a bit confused.
                  Iv looked at the vcore ic NCP81274 and I get
                  Enable 1.8v low?
                  Vcc 5v
                  Vref 2v
                  Pgood 0v
                  I did some digging...

                  Apple 820-3662 VCore shorted to ground.
                  by barry101
                  Hi, Would appreciate some help.
                  I have an Apple Late 2013 15" A1398 MacBook Pro with Logic Board 820-3662.
                  Get charger light but no fan spin or chime. No liquid damage.
                  Found PPBUS and VCORE both shorted to ground. Other rails were ok.
                  Removed VCORE MOSFETS U7310, U7320 and U7330. Found U7330 was in fact shorted.
                  With the 3 MOSFETS removed, get PPBUS and fan spin. VCORE is still hard shorted to ground (0 ohms).
                  Attempted voltage insertion on VCORE to locate short using bench supply set at 1.0 VDC and 4.95 Amps (max current for my...
