Gigabyte RTX 2060 GV-N2060D6-6GD

Hi,

I bought this faulty card for me and I am trying to repair it.
There was missing components in one area so I replace them (I found some boardview and pictures so I figured out the values).

The missing components were C1311, R625, C1221 and R759.

But the card is still not recognized.

I have 12v, 5v, 1.8v on the board but NVVDD_ENABLE is missing.

But the strange think is that the voltages on U505 are good (pin 1 => 3.3V, pin 2 => 1.8V) but pin 4 is only 0.36V !

Do you have any ideas ?

Thank you in advance.

PS : I used the schematic of this post because it's exactly the same on my board.

i think u505 have problem if the require at pin 1 and pin 2 was pass, should be voltage leads from pin 5 to pin 4

[ductranvinh]

you can test by using wire connect pin 5 to pin 4, if gpu block coil not have voltage, maybe some fet was broken

Sorry I didn't see your message.

I ordered replacement parts for u505 / u506 I will see.

I replaced U505 and U506 but still 0.3V on pin 4 of U505 even if I have 3.3v on pin 1 and 1.8V on pin 2 !
How is it possible ?

Yes I just changed Q501 and everything works ! Q501 was not a 2N7002DW but another reference.

check for resistance to ground. something must be pulling it down.

Yes it was Q501 after U505.
Thanks for all.
