    19v rail short voltage injection help!

    i HAVE AN HP MOBO WHICH HAS SHORT +VIN.
    THE SHORT APPEARS AFTER THER CURRENT SENSE RESISTOR.(REMOVED AND TESTED).

    I AM GETTING RESISTANCE TO GROUND 14 OHMS.

    I PLACED A JUMPER CABLE ON CURRENT SENSE RESISTOR AND I APPLIED 2V
    AND I INCREASE AMPS UPTO 0.86 SHOWNING CC ON PS FOR SHORT.
    I NOTICE PCH AEAR IS GETTING A LITTLE BIT WARM.
    I INCREASE AMPS TO 0.9 AND CC LIGHT ON PS WHEN OFF.

    ACCORDING TO PS SHORT CC LIGHT IS ON BETWEEN 0.27-0.86A

    WHY IS THIS!
    CAN SOMEONE EXPLAIN

    THANKS

      Acer Nitro 5 LA-L181p power LED turns on by 5 secs (Short on PCH rail?)
      by Victor Moreira Silva
      Hello everyone,

      I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.

      Well, my decice specs are the following:

      Model: Acer Nitro 5 AN517-54-55T5
      CPU: Intel Core i5-11400H
      GPU: NVIDIA GeForce GTX 1650
      Motherboard: GH51G LA-L181P Rev:1c

      The symptom:
      When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...

      Xbox One S - 12V Rail Short - Q9F1 Keeps Blowing
      by grimacelord
      Hello,

      Have an Xbox One S here that has a short on the 12V power rail. There is no power, beep, or partial fan spin when connecting power cable.

      After diagnosing with thermal camera, Q9F1 MOSFET (NTTFS4C50N) is getting hot. When I remove this MOSFET, the short on the 12V rail disappears.

      I first replaced Q9F1 with one from a donor board and then partially reassembled the Xbox to test. When I plugged the power cord in, I got a partial fan spin and I thought I had fixed it, but unfortunately, the Xbox still did not power on. So I then disassembled the Xbox...

      Asus Geforce Cerberus GTX1050TI-O4G-DIS short circuit in the FBVDDQ rail
      by nagkiller
      Hello everyone!

      This grafic card came for repair, but when I connected it to the motherboard, the board would not start (short circuit in the 12V rail).

      After removing some PLs to isolate the short in the 12V rail, I got to PML1/PML2, according to the BoardView reference.

      Even injecting a voltage of 1V0 and a current of 3A in the FBVDDQ rail, for example, the voltage drops to 0V20 and none of the components heat up.

      The attached boardview file is very similar to this grafic card, which I am basing the repair on.

      I would like some...

      Acer AN515-55-528T FH52M LA-J891P - Short ciruit after PQW1 MOSFET on +1.35VSDGPU rail.
      by joshAU
      Hi all.
      This notebook was showing no signs of life.

      I removed the FH52M LA-J891P mainboard and found that there was 19V at the DC jack.
      However there was zero volts on the two PRB2 and PRB46 resistors immediately after the two polarity protection MOSFETs (PQB11 & PQB12).

      If I remove the PQW1 MOSFET, the 19V rail starts working, and I can turn on the unit - at least I get the fans, and the power light comes on, when I simulate the power button being pressed. No display.

      I tried replacing the MOSFET with a new one, but again no voltage on the...

      MSI B360M Bazooka short on 3VSB rail
      by karlp028
      I have an MSI B360M Bazooka with a dead short on the 3VSB rail (and VDD33 which is connected). The ethernet controller chip (UL3 in boardview) was getting very hot, so I thought that was the culprit. But after I removed it, the short remained. When I added 5V standby power again, I noticed the ground pad where the ethernet controller had been was getting very hot, as was the nearby hole for an m2 standoff.z

      I haven't found the problem component(s) causing the short yet (no thermal cam). Does the heating of the ground pad mean it should be something near there?
