i ve tracked the no voltage up to up9511, ENable pin is 0V on that chip so it's not powering on the rest of the card. but i don't know why

hi ! i have a gtx 1070 gigabyte g1 with some missing voltages on all phases and mosfets except the first mosfets of each line i have 12v In but no output so can someone advise me please ? and help me diagnose that card because i've tried so many things (no soldering only diagnose with probes)...

i ve found the buck controler in bottom (pgu1) and seems good voltage pass through it how do i know he s bad ? well i'm not sure but resistance to ground goes up and down really fast like 20ohms to 400 then go back to 55 ohms then 350 in a couple of second

yeah i see the ITE i've checked these ones and nothing bad i think no short in diode mode and resistance seems good

no problem in the first post i've said i'm new in that kind of thing, i'm trying to learn, i'm trying to read datasheets to know which value i need to check, making my own process here. maybe it's just the gpu but i want to be sure that it's not something else. and i found the controller in the...

wow thanks the fact is, the board is powering on with fan spining and lights on ! i've got voltage at some points like 12v and others but that's just that area which i don't know don't get power ... can you tell me where the gpu memory controller is ? oh and when the card is on, the gpu die...

between all of them i have 1.1 ohm. on all the vrm and vrams area i have between0.9 and 1.45 ohms everywhere

yeay but the problem is i have 0.9 on all the row of inductor all grey ones (10 of them) so i don't understand

i ve measured 0.9 ohms to ground for the two grey inductors on top is it that ?

i've tested mosfets and they re goods no short nothing, what do you call a memory inductor terminal ? can you show me where it is ?

so this is all measures i have so far i think it's possible memory mosfets on the top right are dead ? oh and the little blank square is 1.1 V

i have 110ohm for 5v and for vram 400ohm

but i'm having shorts in diode mode for all my vrams and little caps around them

i can't remember exactly by head but i'll check tomorrow, but i'm pretty sure it was normal value

hello there thanks ! i'm watching many of his videos cuz that guy is a beast ! it helped me many times but for that card i'm stuck !

hi thanks for your answer i've tried to measure voltage in (voltage mode obviously) at the red spots here, i've tried to find a short at these point with resistance mode and diode mode too but nothing.

Hi everybody i'm new here and i'm trying to learn soldering ! I ve got a gtx 1080 strix with no display, show in device manager but crash when driver installed (nvlddmkm.sys BSOD) I ve flash vbios many times with no error (100% please reboot to take effect) When i ve opened the card, and tested...
