HEY HUM ...It's pretty much hard to localise , at the first glance , where , exactly the short-circuit is ..so you have to suspect any FED-BY-VBAT+ component..remove and check ...repeating the procedure till u find the faulty one ...!

Hopefully u manage to fix Soooooon.

mourad is right ,
if still short , u try remove the red circle , if not work , put back

sms-india · 08-09-2007, 07:43

I think u will waist ur time.if u try to remove all main compunents like capecitors , pfo and removable ic's then short circuit in mobile pcb is just like find a small pin in the sea.

amei8141 · 08-09-2007, 07:48

any good idea.........SIR sms-india

if u don have , than i'll try , better than do nothing

sms-india · 08-09-2007, 07:59

sir u misunderstand me. u tell here that u do everything. and u remove and put back compunents, but no results. so if pcb is faulty then what will u do. if u have any solution for repair shorted board, then tell me how ?

amei8141 · 08-09-2007, 08:20

again u misunderstood me ,,
sure i have no 100% solution , so i try to giving him a idea ,
so u meaning my idea only wasting her time to do this fool act
and
i did'nt say remove and put back compunents ,

(sory if i say something not good to you )
