hi at all.. check if mic contact on pcb for dirty or oxide you can try to check first headset connector sometimes it is broken, after check the component next mic contact .. the mic path is mic headset conn cobba ic, for last solution try to resold ccont ic and cobba ic whit ir solder.

Hi, its easy you have to change the serial MIC Condensator which is located in the top right corner (near Cobba) it has value 2x33nF and it is broken od damaged (working 100%) tested.

Hiii just try rehot COBBA IC (10 second) and it can solve many problem of MIC and Speaker....

Sandman · 11-29-2001, 18:33

TO J2000

i don't think that will work at this time co'z i've tried it many times but still no mic.

the only solution to that is to try air-tek's solution first then if nothing happens then i'll tell gsmlord to try your solution.

best regards........

eureka8888 · 12-31-2001, 11:41

is that part number c120?

hooi76 · 01-02-2002, 15:53

Ok, i've tested personally by my self and it's the cobba ic (usually water damaged and it's oxidise inside the cobba ic's balls), so my choice is to take out the cobba ic and then clean the pcb and the cobba ic with thinner and resolder it back... and the mic works perfectly...hope this can solve you guys problems Cheers

gsm-lord · 01-02-2002, 20:00

can u tell with which equipment u can resolder cobba ic?
