You are doing such a great job with your videos !!!! Each one keeps getting better.

[@electronicsrepairbasics_erb]

Thank you so much!

[@Djazeiry]

your videos are getting better and better dude just keep going because you're...unique

[@electronicsrepairbasics_erb]

Thanks, will do!

[@surgingcircuits6955]

Very Useful! TY!

[@electronicsrepairbasics_erb]

Glad it was helpful!

[@stalwartekwere2157]

Nice job.... your a good teacher 👍

[@electronicsrepairbasics_erb]

I appreciate that!

[@francesco6016]

Hi, is there risk of frying components using the multimeter? (i.e. applying too much voltage or current using a given setting)
Many thanks and great video! Cheers from Italy

[@garypoplin4599]

3:06 - If you were to test your meter leads by connecting the other probe to a different point on that ground pad, you would verify the first probe connection as well as the integrity of your meter leads with a single test. Then move the other probe to your test points with confidence of a solid connection to the first probe for accurate readings.

You said a low resistance is bad - what qualifies as low?
For all of my inductors I'm getting a low of 300 ohms. Saw 50 ohms on one.

[@Rams_hobby]

nice, thanks

[@electronicsrepairbasics_erb]

Thank you too

[@ppafan]

Very comprehensive video, great job. Can you also make video on voltage injection to find fault

[@electronicsrepairbasics_erb]

Noted

[@uttamthakur2016]

and also where do need to inject voltage to detect short

[@laptopguy2230]

very nice please do one video on voltage injection. Thank you

[@electronicsrepairbasics_erb]

Ok. Thanks

[@hazemeldemrdash2284]

great

[@electronicsrepairbasics_erb]

Thank you

[@borujawi5629]

great work! and very crucial title , you found region where short circiut is take place but how we can found excact component(s) wich make short may inductor,capacitor ext..?? thanks so much

[@electronicsrepairbasics_erb]

Yes, you are right

[@electronicsrepairbasics_erb]

You are very welcome

[@lvwilb5687]

GREAT JOB. HOW DO YOU INJECT VOLTAGE TO FIND SHORT CIRCUIT .

[@electronicsrepairbasics_erb]

The voltage injection is the easiest way to spot a short circuit. Voltage injection occur on the shorted component

[@kgerakopoulos]

1v and starting with 2amps

Where's Cato Fong inspector?

[@surgingcircuits6955]

I must admit that removing the CPU or like, and getting a higher resistance is baffling me a bit. Seems like it would remove resistance. Is it possibly because capacitors supporting the chip are drawing current from the DMM during testing? Or other? Thx.

[@electronicsrepairbasics_erb]

Keep in mind that the resistance of all chipsets including CPU are low in every motherboard.

[@surgingcircuits6955]

@@electronicsrepairbasics_erb ...yes, agree, but seems like we're adding more wire ... although very small. Thanks for your video and response.

[@zoedubois800]

Hello if the short circuit is in the cpu how to remove it

[@electronicsrepairbasics_erb]

By changing it

[@restingroysurong805]

Mean all the component are bad ? So explain clearly sir

[@electronicsrepairbasics_erb]

Not all of them are bad, just one is bad and infects the others

[@restingroysurong805]

So if we remove the bad one there is no buzer or beap sound coming again. Please explain sir so that I will try my own

[@candrmix]

So how to know which component caused short??

[@electronicsrepairbasics_erb]

Using many methods that I shared in many videos, for example by checking what component becomes hot, etc

Please use modern boards. You cannot remove cpus from modern boards. I have asked before that you should actually do proper troubleshooting from beginning to end on modern boards. This would be very helpful.

[@electronicsrepairbasics_erb]

It's not about old or modern boards, but about understanding how things works,
Regards

[@christiannolan8333]

@@electronicsrepairbasics_erb So if the CPU is not removeable, how would one know if the low resistance is from the CPU or from the circuit itself? I think that is what Dombarton is trying to figure out, including myself -). Btw I really enjoy the content on your channel , it's extremely helpful.

[@shenidan2023]

He's made a great video so stop slagging him down. I am be grateful he has gone to a lot of effort to impart his knowledge
