hello, this card was shorted in one of the phases, the short damaged one of the high dp gate tracks (see photos) removed short, also replaces the PWM (up9509) and the pwm drive, the memory voltage is back, but nothing from vGpu, the conductivity of the gates of the mosfets to the pwm and drive, but for some reason the tenão does not go up.

Are you getting PWM impulses?

compare in diode mode all 3 phases against ground
you take same point from all phases (example gate of first mosfet from each phase) and you should get similar readings normaly ; do this for all mosfets and their drivers
if you get different readings of 1 from those 3 phases investigate that mosfet or driver
