I had watched a lot of videos on mosfets and this is absolutely the best instruction on testing them. Thank you for sharing them. Got a new sub right here.

I had no idea the transistor maintained its state after switching. I thought the input had to be sustained to keep it in that state. Amazing stuff.

This is awesome! Can you do more of these vids? Until your videos came, I didn't even think it was worth it repairing graphics cards. A series for beginners (how to read schematics, what are gates, etc) would be great! Thank you. Hopefully you get more subscribers.

Much appreciate the short intro; nothing annoys me more than those long, loud intro's. Thanks for this content.

wonderful lesson sensei

Thank for the demonstration

Awesome video

MOST-FE ❤ Most faith

thank u for the information ....it will help me a lot 🙂

Thnanks for the class.

Nice technic, though you always have to know the type of MOSFET you're trying to measure i.e P-channel or N-channel mosfet. Thanks for the knowledge

Thanks!

Can u add checking drmos? I dont know if im right what is called, the one with the internal driver and mosfet combined i think.

Thanks for the video ,i have an important question ,so if i want to replace a faulty cpu mosfet and i dont have one ,can i connect two single normal mosfet together with wire and use them as a dual mosfet for replacement ?

Great work

cool!

is the mosfet you test first working properly? I have couple of mosfets from donor card i wanted to use as replacement for another gpu, but the resistance on first channel and second channel is different like on the first one you test, the second mosfet you're testing shows similar resistance on both channels. I worry that if i slap them in they'll just blow up on start @northwestrepair

For the algo!!!

Good work

I dont get how do you "open" and "close". Does multimeter provide some sort of voltage?

I believe this is true only for a n channel mosfet?

wow.

thanks. what issues do you usually encounter with a bad mosfets?

I have a gtx 1080 Aero from MSI and one of the mosfets was bolwn. Since I dont have the the same one for replacmet but have a similar from diferent MSI card gtx 1070 gaming x. The mosfet in question is 4C85N and the one I want to repalce with is 4C86N, they have same pin leyout an similar datasheet. My question is it safe to use that one for replacment or wait 1 to 2 month for replacment ?

Thanks!
