How to identify shorted capacitors, you don’t need to inject any voltages 

Whats the point? I am just trying to learn.

no we dont have

They do go open. They can develop high "equivalent series resistance" ESR. They can develop leakage ranging from in specification to out of spec but undetectable malfunction all of the way to shorted. They can suffer a reduction in capacity usually accompanied by increase in ESR. Look into ideal component characteristics versus real components which all have resistance, capacitance and inductance. Good luck!

Yes, some power rails are connected to a pch, cpu and graphics chip, those chips have low resistance to ground…

@@jbvtechnologies Thanks brother for the information 🙂

Lol

- Over heating - Board failure to turn on - Some components fail

You kinda screwed. I don't think you can figure that out. You'll need a schematic or donor board.

Samee

sometimes you can find example circuits of ic's in which you can tell the different capacitors used

Sometimes rows of caps are of same value so you can measure the one next to it with cap meter. You can guess by measuring other caps on board and seeing most common values. It's all just educated guesses though.

using capacitance meter or smd tester or if you dont have replace with the same size

That depends, when checking it outside the board then big yes, yes …but when connected to the board you should be careful and check the power rail where the cap is connected

@@jbvtechnologies thnks bro..like your video

@@jbvtechnologies Sir , I have a capacitor that I checked outside the board , it gives no reading at all wether it is in diode mode or in resistor mode . is the capacitor dead ?

He meant burnt not bent

@@BrownBoiTech thank you

it's clear for me. turn up your speakers.
