Check this components if not damaged missing,you can also check for
continuity green fuse.

Components are all there and OK.

Battery is draining very fast.
When charger connected PMIC is getting very hot.:eek:

Check black diode and coil near of PMIC if not short to GND.
If short,remove black diode & check again.

Diode replaced.
PMIC still getting hot, and the voltage on the diode is only 1.2V. ??
When diode removed this is also only 1.2V

replace PMIC! i can do this!

i can do this too, if i have a the chip !
Can you also supply the chip so i can put it in myself

yes, i have good chips. i can give you a trustable adress, most chips are fake on the market i know.....

seller msn: [email protected]

his name is tyson. tell him that you know him from me, my name is Matthias.

Yes bro replace PMIC.
Bro Matthias is right.

Any Solutions for greyed Wi-Fi in 3GS? (Water Damage).....+4V are ok on Wi-Fi Module....

Check L15_RF L20_RF if they generate voltages.At C53 vsd2 1.8V if present.
Voltage or CLK problem.

Last time i had that, there was a bad contact in the area C418_RF, C419_RF, and XW18_RF.

Located between the module and the 2 coils

@wites: 1.8V (VSD2) comes from BB-PMU and this is ok. The VSD2 is only a pullup voltage for some signals i think, not? L15 and L20 is this for internal Power-Supply from the WLAN-Module?

@X10robin: I checked this parts already....there is all ok, i know this problem also.

Fact is: The WLAN-Module becomes +BAT Voltage (about 4V). i see some corrosions on the WLAN-Board, but not that strong. Maybe bad solders under a Chip on the WLAN-Module??

Thanks a lot.
I just send him an email.

other prbolem:

iPhone 4: All sounds are very loud biased (sounds like too high gain). when i reduce volume becomes better, but still biased. when i connect earphone, the same there. when i try to make a call, the mic makes a backcoupling and i hear only a loud beeeeeeeeeeeep. in the earphone also the same!

it was an water damage. i removed the metal shield around the NAND-Flash for cleaning. before i had no backligt, sound was ok i think, i can't say! which ic should i try to reball first??

what can that be? if somebody can help me, you get my greatest respect!!!

hi, i was updating my iphone on itune the suddenly it battery gets low n it turned off , now the situation is when i put it on charging it charge for 3to 4 but still battery low show itune cable sign n when it wanted to restore it in this condtion it turned off again saying battery low , i changed the dock and the cable but still same i even chaged the battery but no use
