    High side mosfet of the power supply of the RTX2060 graphic chip burned out

    Hello. They brought a personal computer for repair in which the video card was GeForce RTX ™ 2060 WINDFORCE OC 6G (rev. 1.0). Graphics core power mosfet burned out.
    Is there a chance to restore the site where the mosfet was? I started to grind the mosfet substrate with a dremel, which stuck to the board, but for now I stopped and decided to ask you for advice. I also noticed dark spots on the PCB near the video memory chips. Does this mean that the video memory is out of order? I cleaned the place where there was a burnout, a short circuit of 12 V was removed. On the coils on the power supply of the chip 1 ohm, on the power supply of the memory 36 ohms. Are these resistances normal? I have not encountered video cards, so I ask you for help.

    as u see u have MANY free phases. just move mosfets and few components to free phase

    just grind until u dont have short on main 12V phase

        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
        by Tynan Dill
        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

        Upon bringing it home and plugging it up, it showed a standby light.

        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

        The screen seems to blackout and stay black, but with a flashlight I can see the display.

        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

        Assuming...

        Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
        by sam_sam_sam
        I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

        One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

        general question when a mosfet on primary of transformer is burned
        by Wolf1977
        hi
        in a welding machine i had a mosfet and four components wich connect with it burned
        i ordered all the damaged components and replace it but when i put the device on the plug all the components burned again i had tested before and i had not shunts
        i dont understand whats happen wrong
        more particular on the schematic q11p01 mosfet q11p02 tranzistor
        three paralel resistors had burned q11p07 zener shunt q11p08 open
        when i changed all these shunts q11po7 mosfet and tranzistors
        maby the transformer has problem on your opinion or something on...

        Any Idea for repair L13 Gen2 LAR-2 PD Charger Mosfet CSD87501L always Burned
        by Mike_Ho
        Dear All

        Anybody have experience to repair L13 Gen2 Board Number : LAR-2 PD charger problem?

        I have one board the U4201 CSD87501L are burned and the 20V_VBUS_USB2 can't switch to 20V_VINT_IN, after replace this Mosfet it's still very HOT and just use few hours will burned again. i have repeat replace this Mosfet 3 times and all dead.

        After that i try to shorted Mosfet Source 1 to Source 2 to bypass the 20V, and found the Control Gate 1 and Gate 2 voltage both are 20v same with 20V_VBUS_USB2.🤨

        So did anybody know this case will need to replace...

        How do you test MOSFET in laptops ?
        by Jane
        I tried to use this method:

        Testing an N-channel MOSFET:

        Step 1: Discharge the Gate (turn off the MOSFET)
        Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
        Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.

        Step 2: Charge the Gate (turn on the MOSFET)
        Now, place the red probe on the Gate (G) and the black probe on the
