if it still doesnt work. ill bake it for 10 minutes at 200C and see.
better dont. it is very likely that this will totaly corrupt card. you dont have problem with desoldered core. simptoms you describe are not simptoms of desoldered core.
i tried it with the multimeter ousude the case, with just the power connected.. fans dont run, vrm doesnt get volts,
but after i put it in the slot, the voltage is going past the vrm(3.3V0, but the voltage around the core is 0.
i think this is a dud.
i booted with both cars, nothing got detected.
check other components on the line between vrms and core. it is either them or pcb rail has failed.
i did check one cap and the coils. they have volts. no scratches visible. but i think this is more than a two layer PCB, right?
not 100% sure bust most likely yes
I would say anywhere from 4-8 layers. Cheap motherboards are usually 4.
Try this. Connect the card to the slot and connect power. Take a multimeter and connect the black probe to any ground terminal of your PSU or any part of the chassis and the red probe to the points as shown. Check the attachment. The card is my card. Your's should have similar design.
already done. those points have voltage. after that there is not voltage.
Then I think that voltage controller IC has failed. I doubt any soldering joint has gone bad. Also try a heat air gun and reflow over all the components. Best of luck.
as i said, its giving correct volts. 3.3 volt is going out of the vrm. and passes the coils and caps. then i couldnt trace it. too cramped.
heat gun same as the oven.
I suggest you give it to a service center. If its a minor power related problem which I think it is, then you can have it fixed cheap.
