I got a K750i in for service, it can't charge and the official SE service center rejected it cause it's water damaged.
The problem is that a small drop made the pin12 platin disapear, but isn't there a point i can reconnect pin12 to somewhere on the board? any help is apreciated

Best Regards

anyone got a service manual?

@SubTen - can you not just re-plate the contact - I'm sure electronic shops sell 'pens' for such a job! Or is the damage worse then I see in the pic?

I know it's hard to see on the picture, but the line to pin12 isn't vissible, it's in a deeper layer and there's only a microscopic VIA hole left, so the pen won't help me

Thanks mate! Im testing this right now

For me it looks like you've made a circle around 2 components, but the upper one has "C2" written on it, and the other one has "HD" on it, hope this helps, or else, tell me how I can help you with it

My old HP scanner could scan HIRES pictures of pcb's, but my new Canon scanner is making the pictures very blurred when the opject is lifted 1-2mm from the glass platten, so I can't make a better picture right now, but im 100% sure that it's {HD} written on it, just checked it through microscope...
and thanks for your sollution... the phone works perfectly right nok
