the main one I would like to fix right now doesn't power on at all.

I have changed the motherboard into another phone which is working perfectly and has a charged battery. it does nothing.

I think it may have been plugged into a cheap charger at some point.

I have tested for voltage at L9 and there is ~3.5v at both pins. there is continuity at the little pair of inductors which most people label as fuses, and also at the green battery resistor/fuse.

Any ideas?

#2

this phone has taken a dip in the ocean, when I got it every crevice was full of sand.
it seems to work perfectly except the display is scrambled with mostly white vertical lines through it.
I have put this motherboard into a good phone and the problem goes with the motherboard.

what area is likely to cause this? there arent really any white deposits on the board from the water.
I have given it a rinse with isopropyl too, which actually seems to have made it worse.

Any help with either of these phones would be greatly appreciated!

Hey Wites,

looks like you're the man for this sort of thing, I've been reading your posts and downloaded your iphone 4 schematic for later use.
I've had this persons phone for a while now (wont turn on) and I was wondering if you can help me with it? of course I understand many people here want your help.

Thanks!
