    HP LaserJet III - ERROR 50

    I no longer have this printer but inherited a defective one which I repaired using the following instructions:

    The faulty board is numbered RG1-1438. The problem described is capacitor C153 (22uF@25V) has leaked and has created a short on the circuit board. The fix is to cut a trace to remove the short, resolder it with a piece of wire and replace the burst capacitor.

    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...

    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.
