Sin chanthoeurn · 11-02-2011, 14:55

this resistor brother! . i exact 100% because i borrow resistor for other iphone4 put it on my board it power on fine!

kostelectronics · 11-02-2011, 15:00

you saw my post? i will check the value as soon i'm at my workshop. But i must remove from board to measure. why you didn't measure when you pulled from other phone for testing??

mehulkr76 · 11-02-2011, 15:03

it can be low ohms coil also.

kostelectronics · 11-02-2011, 15:09

@mehulkr76: yes, i thougt this also, but when i measure, i ged a very high unconstant value. maybe the BGA-Glue or something. i will check it exactly this evening.

bro its power ic not audio ic make bolls agian ,maybe when you try to change it its rehoot the main ic its so risky and carefully work you contact me at sonrak id100.1607930

Sin chanthoeurn · 11-03-2011, 11:48

yes! brother KOSTELECTRONICS speak right ! ,only need the value of this resistor!.....now my PHONE still DEAD..DEAD...if know value can take from other like 3G or 3GS

I can't understand if hi borrow resistor from other pcb why hi didn't check value from that resistor rather then asking here to do for him other members.
Did hi make clowns from you?

resistor near audio ic if removed phone wont boot.i checked it too.i was shocked when after removing the audio ic the phone did not boot i have many experience replacing this audio ic but this phone didnot boot than the other.finaly i found a resistor was missing after replace before fixing the audio ic the phone booted now.
