Moi drodzy jeśli ktoś z dobrych dusz mógłby mi pomóc to będę wdzięczny bo już kota dostaje i błądzę jak ślepy w nocy po lesie :(

Nie mogę znaleźć źródła zwarcia na płycie HP DAG3BEMBCD0 REV D na cewce zaznaczonej na żółto ( wartość rezystancji 1,56 ohm ) ...jest ona podłączona do układu RT8816AGQW ( bez układu bo na próbę go wylutowałem rezystancja jest taka sama czyli 1,56ohm )

Będę serdecznie wdzięczny za jakąkolwiek pomoc

Hello!
And why do you think it's a short circuit to ground?

The GPU core power supply (power rail "NVVDD") is separated into two parts on this board (power rails "NVVDD1" and "NVVDD2").
The coil marked in your picture is a second GPU core power supply ("NVVDD2" power rail) on which the given resistance seems perfectly fine to me.

And You are perfectly right :). After i have taken a deep look into that motherboard and a schematic it all make sense and was a clear case :)

But thank You so much once again for a reply and proving that my assumptions were correct :)
