Da0zqfmb6f0 rev f shorted

Hi i dont know where to find this section of ic on the schematic it showing shorted line





schematic attached also

Re: Da0zqfmb6f0 rev f shorted

What is the exact resistance on that coil?? It is supposed to be low. Why dont you remove the coil and see which side is shorted?

Re: Da0zqfmb6f0 rev f shorted

0.8 OHMS sir

Re: Da0zqfmb6f0 rev f shorted

too low.. it is probably a shorted smd cap.. inject 1v 1A and hope something heats up..

Re: Da0zqfmb6f0 rev f shorted

I remove the coil and inject voltage and amp but nothing heats up sir

Re: Da0zqfmb6f0 rev f shorted

I see a fet missing in your pic. have you soldered a new one there?? 0.8Ohms may not be low if that coil is part of vcore circuit as cpu is onboard. Btw, which side of the coil is shorted?? Remove all caps near the coil and check them out of circuit.

i already tried changging the mosfet and checking all the coils showing some of the coils is shorted

Re: Da0zqfmb6f0 rev f shorted

those readings are solid short circuit.. try to remove all the coils to isolate the circuit.. then try to test it again where is the short coming from.. happy hunting!!!

This is diode mode, not resistance mode. Also attach pictures directly to your post with a better resolution (and without random shady links).

Re: Da0zqfmb6f0 rev f shorted

did you find the short circuit? he is using diode mode and testing the circuit with red probe
ground and black probe for poking. did you remove all the coils?
