    xbox 360 blowing mosfet

    Hi Folks:

    I have an xbox 360 that had a shorted USB pin. After unbending it and turning it on it came without video and red ring. I tried the towel trick and it came up with video. Then the power source led turned red and I heard a mosfet failing. I tested the mosfets and found the two 5v mosfets were shorted (they showed as two resistances on the tester). I replaced them but now the one closer to the CPU is shorting everytime I power it on. If I remove it it starts with red ring.

    Any ideas of what could be failing? Maybe a shorted capacitor? What tests should I do?

    Regards

    Asus GA502D keeps blowing mosfet
    by Scotchmist
    I have an Asus GA502D, it had a blown mosfet which I replaced and the laptop booted into windows, a few mins later it shut off, the same mosfet was blown. I thought maybe just a bad mosfet but same thing happened again, a few mins in windows and shuts off.

    I have removed the mosfet and can run the laptop no problem

    The MOSFET is FDPC5018SG

    Can anyone point me in the direction of what could be the cause of this, could it be the controller rt3663bc?

    Thanks

    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

    An Xbox One PSU Odyssey

    Firstly I am not a tech. You guys may see mistakes or oversights in my methods so don't be bashful and feel free to post corrections/opinions.

    =>Background:
    I bought my son a used Xbox One original model: A12-220N1A Rev: 02 with original PSU & 2 controllers 7 years ago. I “modded” the unit placing a 4.5” 12V exhaust fan with a 9v wall wart adapter on top of the vent/fan of the unit. And plugged the Xbox PSU into a Tripplite LTR-600 voltage regulator. Also connected to the Tripplite are a 275w computer tower, an Xbox 360 PSU and a Westinghouse 52” LED TV. ...

    Xbox One S - 12V Rail Short - Q9F1 Keeps Blowing
    by grimacelord
    Hello,

    Have an Xbox One S here that has a short on the 12V power rail. There is no power, beep, or partial fan spin when connecting power cable.

    After diagnosing with thermal camera, Q9F1 MOSFET (NTTFS4C50N) is getting hot. When I remove this MOSFET, the short on the 12V rail disappears.

    I first replaced Q9F1 with one from a donor board and then partially reassembled the Xbox to test. When I plugged the power cord in, I got a partial fan spin and I thought I had fixed it, but unfortunately, the Xbox still did not power on. So I then disassembled the Xbox...

    VGA MOSfet permanently shorted and loss of MOSfet pad
    by Nooy
    Hello everyone, I recently found this badcaps site and super Learn Electronics Repair youtube channel. And I wanted to learn how to troubleshoot power supplies and VGA cards and how to practice soldering, since I already have a properly defective piece of them. I am currently trying to solve two problems:

    I have a Gigabyte GV-RX460WF2OC-4GD type card. I managed to find the faulty MOSfet (AON6414A) on it, which I replaced. The card starts up, but after about half a minute, the MOSfet in the same position will be shorted again. Is it possible that the PWM controller driving the MOSfet...
