Battery Charge problem since it fall on the water

Hello,

I have a problem with my iPhone 3G it doesn't charge the battery any more, i changed the dock and the battery and it still doesn't charge the battery.

Any idea, do you think the problem it's from the mother board ?

Thank's and have a good day.

First I cleaned the LogicBoard with a contact cleaner and after that nothing, no charge and you are right when i plug the USB charger there's no message like before "Charging" it simply not charge.

I'm going to check the fuse right now and i keep in touch.

thank's a lot

I take it that there is Know fix to the fuse going but to replace the Logic board?

i think some people have made a small jump of solder and very fine wire when small fuses like this "blow. have seen this for capacitors near connector 4. you could try googling the part if you've the fine soldering skills/equipment. I'm sure there is a site that has a list of all the small component parts and who made them, when I relocate the link i'll add it- if you fix it you could post back so others can learn!

logic board is a bit expensive to replace...

Chosen Solution

did you clean the logic board with alcohol or an electronics cleaner ??

(would be the first thing i would do)

does the phone react with a "not charging" message of any kind or does it simply not charge ?

if you cleaned the logicboard and it still does not charge, it's possible that the fuse is shot.

there is the yellow line going to the skyworks sky 77340 - when you follow the yellow line on the picture - it almost touches a greenish part - thats the fuse - if this one's shot - your phone won't charge

edit: i added a picture where i marked the fuse ;-)

Very good details +

Can I do "short" where fuse is and should works, or I need to change for new one?

by

either..if you change the fuse it would be better...it will blow in any power surge instead of an expensive chip. But it's up to you...a blob of solder does the trick
