hi sir, i have this laptop .. msi ms-16jf.. shorted polymer capacitor.. everytime i replaced the capacitor when i power on it damage again.. by the way i replaced it with a differen code but the same picture.. please see the photo.. do i have to replaced it with the same code value?

if I did not replace and left it vacant , the laptop power on but no display...

remove capacitor and check voltage . maybe this point have over voltage problem ,.

i removed the capacitor and chexked the voltage it gives 19v .this capacitor s near to the cpu coil.. when i removed the capacitor and try to power on, the laptop has power on but no display

You need to same value(preferably)... if it blows, that means u might have more shorts(possibly)...
This capacitor, which line is it on?

 

[user24495]

on that red circle bro..

Thanks..Check short on the MOSFETs connected to that cap.... that's a smoothing capacitor connected to coil(possibly) i can see 3 caps(they could be smoothing caps) close to PCH.. Just use diode mode and test around Output from on of the iC's.. I think the one that is shorted is the output cap after Coil.

U can take out the cap, check if its still short(diode mode). then continue to take out some components Mosfets, check again, and continue like that..trace back to the short.. Most people are to afraid to take out components in the beginninging.. just remove them one by one.. and test them and retest them.. I use to be like that, these days I just remove anything on the potential faulty line.. until I find the problem..

It was the gpu , I reflow the gpu bro.. and i did not replace the capacitor i totally removed it ..the laptop is now functioning,, im just worried if it is ok that 1 capacitor is missing, although the laptop is perfectly running..

That's good u got it working.... check schematic.. if its a filter cap, then you can leave it out without replacing it (if u have more caps on that line)..

if its working,just leave it as it is..

the problem is that this model has no available schematic thats why .. but anyway thank you so much bro for guiding me

That's good work then without schematic.. Ps. you're welcome..
