Thread: Water damaged 3g questions??
01-28-2011, 08:05 PM #1Water damaged 3g questions??
Bought used iphone. Both water sensors activated. Battery was dead changed charger port and installed different board. Everything works the way it should now. When I reinstall activated mother board I get nothing. Not recognized doesn't charge. Nothing.
My question are:
1/Is this a parts board now or is there a possibility of bringing it back to life? And how maybe?
2/ I read somewhere that bleach when applied to indicators it will reverse action turn them white again. Any input?
3/ Is there a good paste or rosin to use so that corrosion doesn't occur a later date?
4/ Is there a good contact cleaner that will work to set up solder joints?
5/ When remounting mini components on motherboard, would a person use an iron or if using heat gun how are small parts held in place without being blown off of board? Wood, tooth pick?

You can try washing the logic board with as close as 100% alcohol as you can get let it set o\in it for 10-15 mins then take a soft brush, and brush away the corrosion.
And what parts are you trying to take off exactly??

There doesn't appear to have any corrosion. Board appears clean. I tried wiping connection areas with a cue tip and some contact cleaner and had no luck.
Parts I am going to attempt change are the choke coil at cell antennae and several capacitors at the battery connector area. Battery is not charging on this board and parts are missing. (It is only good as an Ipod right now with no phone activity.) They were wiped off the board by the previous owner due to an accident.
If I can post links for pics of my problem areas I can do that.
thanks for your reply

Hope this works as you are working with a nerd here.

I hope this is understood. The #s1 and #s2 go together.
Took awhile to put these together.
thanks for the replies.
Hope you can suggest something.

Hey I got your message. Looks like you removed some inductors off of the phone. Some of the clear ones on the bottom of the phone by the antenna are crucial to it powering up. I had one with the same issue. If you can take one off another dead phone, it may work. I have not tried it but its worth a shot.

Hi Krazy, I know you suggested you hadn't replaced any inductors, but, if you were to, would you solder or use a heat gun, to remount?

Definitely heatgun. Not the off the shelf type, but rather a hakko hot air station with a tiny nozzle.

yeah you might want to take to an expert that isnt easy to di
