    e114139 94V-0 dc-jack short to ground

    Hello,
    I have a laptop mb e114139 94V-0 which blow a capacitor (PL1) near the dcjack.
    After I remove the capacitor I checked the dc jack and all pins (1,2,3) are short to ground.
    I couldnt found schematics and I don't know if this is a mosfet problem.
    Can someone guide me to test what is going on?

          pl1 should be an inductor.with it gone the short is most likely at or near the jack.
          looks like maybe a burn thru at the jack side of pl1.start there.

              Thanks a lot for the schematics meritosari.
              So if I remove the jack you think it could be fixed or it may be burnt down the layers?
              Could it be some other component short ?

                  Update:
                  I removed jack and pc1. Jack is ok but when I measure 1,2,3 in jack position on board it shows short to ground.
                  How can I clean the board in that position so I bypass the short?

                      The problem was that after PL1 blew up it short the dc jack line. I cut all lines from positive voltage and just connect it to one end of the new pl1 and it worked. Thanks everyone for your help and espessialy meritosari for the schematics.

                          hello everyone , working zebronics power suply 450 watts , 5v ,3.3v givin short to ground black wire, also in circuit at output, resistor was charred but shows right values , after removing resistors 39ohms, 51 ohms, there was no short , no continuity beeps with ground , but after replacing new resistors (now i am not switching it on) ,again short still exists . when i put bigger ohm resistor like 100k ohm , no short beeping sound comes , lower ohm resistor gives continuity beeps ,other big ones donest , as its a working psu , i am confused what to remove now or how to go further now .

                          820-00840 / No boot / PP3V3_G3H Short to ground
                          by MisterAIL
                          Hello everyone,

                          Firstly sorry for my english, french guy inside.

                          I brought a macbook pro A1708 - 820-00840 logic board, wasn't powering on.
                          History is a day, nothing happened when opening the laptop.

                          Nothing special inside, no corrosion, no liquid damage, never opened.

                          First, with the logicboard alone on the desk, mesures are :
                          5v017 and 0.000 amp. nothing else.
                          Finding a short on the PP3V3_G3H_VR, but not on the PP3V3_G3H (0.540 on diode mode), PPDCIN_G3H_CHGR_R present (5,1 volts) PPVIN_G3H_P3V3G3H around 4.1 volts. PM_EN_P3V3_G3H...

                          suspect mainboard.
                          disconnecting tcon has no change on operation.

                          PS5 - long screw damage, via to ground layer short?
                          by Prott
                          Hello dear Badcappers,
                          I came across a PS5 that was longscrewed. The screw went through the HDMI IC (which I replaced + repaired the traces it damaged), however the screw also bend the board and slightly cracked it on the other side. It still seems like it could be fixable though as the area might not have lots of traces going through it (fingers crossed).

                          Can somebody, please, measure their board and tell me if my assumption of an inner short between the via and ground layer is correct? These 3 pads have almost no resistance. I would like to make sure those are not some data...

                          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...
