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...09-27-2024, 03:31 AM -
I'm working on a LED circuit board and am testing a 8C 1A component, it has a wide ground tab on one side and 3 tabs on the other and the center tab is grounded also. the circuit board has it as a V2 component ,so is this a mosfet or transistor ? -
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... -
I have a Razer laptop (RZ09 MB# CH570_MB_NT) that has a shorted mosfet marked BND M03 E067 that I'm unable to find anywhere online. Does anyone either know what the part number is for this mosfet or have a schematic I can find it in?
Backstory on the whole thing the laptop was plugged into a lamp at a hotel. The lamp got unplugged while it was charging and now the system won't power on anymore. I found the caps around this mosfet shorted and when I injected voltage into the caps the mosfet got hot and my bench psu was pulling 5A. Pretty sure this is all that's wrong with the laptop... -
This is an lcd display used on ebikes.
long story short, there was condensation inside the unit.
I opened it and thoroughly cleaned the pcb with isopryl.
The board had no visible corosion.
It powered on fine and was tested for an hour or so.
However when connected to the bike,,it did not power on at all.
I took it home and reopened it to take a look. There are no shorts based on MY testing.
However,,when I probe the transistor and the mosfet gate in diode mode or contuinity mode, (one probe on transistor collector and one probe on mosfet gate}the unit...09-16-2025, 12:56 PM
