    N5010 DG15 shorted Mosfet 3.3-5v Low side

    Hi im working with this DG15 .
    the client has given a handful.
    i checked :
    PU4601 to hot , replaced with TPS51125 also to hot again , after i checked 2 mosfet low side PU4605 - PU4604 Shorted with Gnd . removed these and measured and are OK ,the short is on coil (PL4601 pin 1 -PL4602 pin 2) so

    3,3V_ALW and 5V_ALW are shotrted with gnd ,

    apply 3.3v 3a on shorted side of coil PL4601 And heat up Igp HM57
    apply 5v 3a on shorted side of coil PL4602 And heat up Igp HM57

    so HM57 is to replace or any other suggestion?

              hi today i m working with another DG15 identical problem , but on this not heat up anything no 3,3-5v and these coils are shorted with ground no 3,3v_pwr and 5v_pwr.

              when i apply voltage with PSU nothing heats up . any advice please

                      VRM shorted, low side shorted ?
                      by Bousty
                      Hello,

                      my motherboard, a Gigabyte b660m-DS3H, broke last night, and I'm trying to fix it.
                      The symptoms are as follows:
                      - The PC doesn't boot when the CPU power supply is connected (without CPU).
                      - When voltage is applied to the CPU connection, the three phase 2 MOSFETs start to heat up. The other MOSFETs do not heat up.

                      The phases are made up of one high-side and two low-side MOSFETs.
                      My hypothesis is that if the two Low MOSFETs are hot, they must be permanently ON, even when the High is ON, causing a short-circuit.

                      Do you know how...

                      Panasonic TC-P50S1 shorted TXNSC1EDUU (TNPA4782AB) SC Board
                      by Yanleb
                      Hi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.

                      I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :

                      D608, good
                      D618 RF101L4S, good (See warning 1 below)
                      D619 RF101L4S, good (See warning 1 below)
                      D865 RF101L4S, shorted (See warning 1 below)

                      Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
                      by flibidy
                      I have here a Magnum IA.100 which belongs to my parents.



                      The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


                      Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.


                      What Ive done........

                      Dead Razer Blade 14 2022, shorted CPU?
                      by BalkanBoy
                      Hi,

                      today I got Razer Blade 14, Ryzen 9 6900HX and RTX 3070Ti.

                      Laptop was completely dead. I found shorted CPU VRM mosfet, shorted 19V mosfet and blown battery fuse.

                      I replaced it all, but still on CPU coil where mosfet was shorted I got very low resistance, near 0 ohms. On other CPU coils I got around 3 ohms.

                      Laptop now raises voltage on whole board, but still nothing comes on the screen. CPU gets 0.7V on all coils except the shorted one. CPU gets only slightly hot, below 40 C.

                      I removed coil and injected 0.7V, it draw around...

                      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...
