What is this part ?

[Jueyyy]

Hey everybody,

i am starting to get into repairing gpus i have plugged this gpu in and nothing, fans dont spin nothing. Then i opened the card up and looked for obvious defects and i stumbled across this, it looks like a corner has broken off and now i am trying to find out what it is and what else could be effected 

PS: its the part labelled LR33

Looks like an SMD inductor.

I'd voltage probe it to see if it still conducts. Looks more like some filth than damage to me.

what it is

It's a 0,33µH (+-15%) high current SMD inductor, likely part of the power circuit.

It appears to either just be dirty, or, as you said, have a cracked corner, which shouldn't affect it a lot.

Just the ferrite. Doesn't change too much if it is cracked.

no its broken off and i tested the capacitors on the right of it and they are all shortet to ground

i guessed that it had soemthing to do with power cause the fans wouldnt spin and id get bno picture put the shortet capacitors next to it got me thinking

also what the part below ? and should it be connected to ground on both sides ?

The part below is a diode, it allows for current to only flow in one direction.

Current flows from the unmarked side to the marked side. If you set your multimeter to continuity, you should only see continuity if you connect the black lead to the marked side and the red lead to the unmarked side.

Are both sides of the capacitors shorting to ground?

yes they are but sadly i dont have a  lab power supply and thermal camera or flux (atleast right now) so i cant see what gets hot when i insert voltage at those capacitors does anyone have any alternatives?

What model is this GPU actually?

 

As for what you can do: Probe around with a multimeter, becaus sometimes you find something with that as well. (also a general tip: find a part code deciphering table/tool online, they can help a ton, just keep in mind that codes aren't the same across different types of components)

i did probe around but i dont really know what to look for and those capacitors and broken inductor is all that i found
