Hi all, first of all, I am not able to find the schematics or boardview for this gpu model, so I am hoping someone here will point me in the right direction. I am a newbie.
This gpu fans all stopped working after doing fan replacement. Some components of on the pcb board blew up during the power up. The cause of this was realised shortly after that the 12v wire
was carelessly caught in a screw which in contact with the fan shroud. The fan shroud of this gpu is made from metal and hence shorted to ground.
Attached pic of the pcb with the burned component and pic of another board of the same model.
Prelimary testing shows that the transistor near it is also now need to be replaced. Probably the tiny resistor and capacitor near it too.
How do i go about identifying the blown up component. I measured the resistance from the other board but its like less than 1ohms.
The transistor with my limited experience, I think is a pnp transistor RST 93 (correct me if i am wrong)
