rx 5700 pulse Schematic & Boardview request 1.8 missing sometimes present

[Lucifer87]

Hi, I need the schematic and boardview of a Radeon RX 5700 Pulse, sometimes it turns on, sometimes it doesn't... I checked when it doesn't turn on, the enable signal is missing on pin 15 EN2 3v to power 1.8v... the problem is that when it works I can't test it since the signal is present... I would like to check the signal paths but I would need the diagram and the boardview thanks

Do you own an oscilloscope?

no I have a tester... I sometimes get 3V on pin 15 (EN2 ) and the card works then sometimes it doesn't arrive and the card doesn't start...so the 3V is missing EN .I don't have the boardview of the card so I can't follow the tracks...

I have ASUS, GIGABYTE and MSI boardviews for the 5700 and 5700 XT if that might help...some boards are based on reference boards. I am not sure in your case.

unfortunately all these boardviews are different, they all have the gs7260 controller ic, I needed the specific one from the pulse which mounts an NB685GQ

I did some checks, I traced the signal and checked the voltages, the 3v en2 signal that passes through these points and it is not present... what I don't know is where the en2 signal originates, who produces it? I attach some photos
