Video/Graphics card troubleshooting

July 30, 2019 posted by


This GPU isn’t working , let’s check for any short bad component one leg of the capacitor should be connected to ground and the other should not if they are both connected to ground it means that capacitor is bad i found a faulty one , let’s mark it to remember were it was something is missing there This N-channel Mosfet measures bad This capacitor is shorted I think the problem is only the capacitor because it is in series with the Mosfet transistor and that’s why the transistor measures bad let’s remove the capacitor and hope this Mosfet is ok thank you for watching 😀

    good Job, but bad mosfet causes overvoltage and this Card is absolutly dead.

    I followed your whole diagnostic. I see the bad cap. I see the other small unit on the back. 2 units maybe, until cap is changed then maybe mosfet? I would suppose then a whole unit test? For picture? If no, then the missing #60? Or?

    Ye so nice and if happen this and card still working is cool https://youtu.be/WLuMd-osAbs

    not sure, but the first resister you ;put an arrow to may not have been bad. The large cap was bad, but I never saw you reverse the leads on the mosfet, you were saying was bad. It would be a diode in that direction, and would show continuity, but reversed it would not. Probably bad but may work with just the large cap replaced.

    If checking a graphics card with multimeter then talking about a nice troubleshooting.99,8% there is a reballing reflowing matter of issues.
