Missing capacitor on motherboard

the capacitor (?) that I circled here is missing on my board. The phone doesn’t power on. Anyone knows what it does and what to replace it with?

update: I found it is c2721, where can I find these capacitors? (I live in the Netherlands)

another update: I got in touch with a motherboard repair shop who is going to give it a shot to repair. He has a ‘No cure No pay’ policy so I guess we’ll see. Thanks anyways!

That missing capacitor would not stop the phone booting. What would be more important is why it is missing. That line I think is a CPU power line and since it has another 6 capacitors on that line I would not be concerned.

As for why your phone is not functioning we will need some more info.

· How did the phone become like this?

· Is it recognised by iTunes?

· Does it draw any current before prompt to boot?

It is not recognized by iTunes, neither does it draw any current. I don’t know how it got in this state. I bought the phone like this, the seller told the phone was dropped and not functioning after that.

I tried a screen and battery that were confirmed to work and I still did not get anything. The seller said there was never any work done to the motherboard but the shield and sticker covering that capacitor were missing. So I doubt that he’s telling the thruth.
