    Extreme High Current & Low Voltage Short Killer ??
    by DynaxSC
    Hi Folks

    I'm looking for a extreme high current short killer solution for a reasonable cost.

    I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
    After taking off the socket, the shorts dissappear again.
    The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

    Gigabyte GTX1080 - identifying a dead short on vmem
    by Prott
    Hey!
    I have a problem with Gigabyte Aorus 1080. The card seems fine (expected resistance on vcore, pex, 5v, 1.8v, 12v and reset) except for a dead short on vmem (FBVDD). It's interesting failure mode, cause usually (in my experience) when memory fails it still retains a few ohms - this one is literally a dead short.

    I removed the inductors and tried inject voltage (0.8 V at 6 A) which only seemed to warm up the cables to the card while the card itself didn't show any hotspots.

    Is there any way to narrow down the search for a short? I would prefer not to remove...

    LG OLD55CX6LA TCON Short - Help Identifying Component
    by spookt
    Hi Folks

    I've got a friend's LG OLED on the bench (well the dining table given the size of it!). It immediately powers off when turned on and sits in standby. PSU voltages are good and after disconnecting the TCON board there is stable 12V and 22V coming out of the PSU board.

    Hunting around the TCON board there appears to be a shorted power rail (DVDD09_CORE) but I'm having issues identifying the component which is shorted. I've attached a picture. It's sitting before the coil so I'm assuming it's a MOSFET of some description, but the markings I can make out don't seem...

    MacBook Pro 14" A2442 Short on PPBUS_AON but no short present when injecting voltage!
    by Stephen
    I check PPBUS_AON and there is a short present on the line, the computer shows a short when testing for short to ground, so when I inject voltage into the line, I get 0AMPS so no short is showing up. I have replaced a blown cap on this board that exploded and tested for the short and it is now removed. Any suggestions? I tested voltage at the line when the fuses are connected and I am getting 1.2 Volts at the line.

    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...
