    Default Problems with Iphone 2G

    Hi. I have a few problems with my Iphone 2G:

    1. It turns on only if connect to charger
    2. It charges only when it's off
    3. Can't wake up the phone from stand-by, except connect it to charger or remove-insert sim card.

    Otherwise the phone works exccellent. Everything it's ok - wifi, bluetooth, can receive and make calls, sound and mic also ok. When it's on all the butons works fine. I can turn it off by power button but can't turn it on. All the problems start when my friend drop the phone in the pool. After that it was dead. I opened it clean it with ultrasonic vane and it stars but no lcd backlight. Then I resolder some of the legs of the lcd board connector and the light comes on. I check all connectors, diods, most of rezistors, I think they are fine. But I stiil got problems. Where I should search the problem - com or logic board, or which one to change-com or logic board.
    I will be very thankfull if anyone can help

    There is some progress in my case. The phone now charges ok - the charger was faulty. But still can't switch on with power button. I tried different logic board from other phone just for the test and everything was ok. So the problem is in the logic board. I noticed that on logic board there's a missing crystal - the one with circle and red dots in the photo . There are only 8 pins /I draw them like red dots/ and no crystal. This crystal is the same like the other one on the photo and has these letters "73NDE7". I can't find any datasheet for this ic. Do you know what is this cristal for or have a datasheet or jumper. May be my problem is in this crystal. Thanks
