iPhone 4 dropped under water, WiFi grayed out


Hi,

I have an iPhone 4, this one was dropped in water.

The WiFi was grayed out until then, I disassembled the device and cleaned with a contact cleaner, but nothing changed...

So I dig deeper and removed some of the metal blocs that protects the motherboard, and I came across a short circuit spot (or smt like that).

And this one corresponds to this component which is likely a capacitor.

And I'm wondering if it's possible to repair it, and if it's the cause of the greyed wifi.

I can't post images, can anyone guide me?

Best regards,
d3monCorp

I fixed the issue by linking the upper contact of the C141_RF (near to the WiFi chipset) to the VCC contact of the battery.

I would have liked to post some photos but again I can't in this forum.

away to get an Iphone 5. It doesnt charge or sync.

Could it be a faulty dock or will it be the U2 IC?

Iphone works with battery that is charged from another phone.

thanks
