hello,can u give me idea on how to replace the mic of k750i? im having problem with mic, do you have schematic r diagram on how to do it ... thanks

Platijet · 09-12-2006, 15:31

use "search" button.there is many threads with solution

gachero · 09-15-2006, 15:43

i change the mic using t610. with 1.2k resistor,in series with it, its working rirht now...
thanks for the solution.....

substituting k750i mic with t610(with series 1k resistance) works 100%
THANKS FOR THE SOLUTION

Hi I removed my K750i mic with a sharp blade, but how can I measure e 1.2K resistor in other phones???

6110 · 02-09-2007, 22:20

plz help me i trye to put 1.2 k risistar but mic will not work plz help me what can i do sir

O.k I fixed mines. My problem was that I dont have a technician background, but trying we can get solution 4 everything.

I have a waterdamage Nokia 3310 ordinaire Board.
In between the sim-connectors (just were the simcard connects to the PCB) I took the smallest shiny black part (there are 2 of them). According to the Schematics attached above by MUJIE, I soldered this small Resistor, without knowing it is K1.2 or not, to the board where it is draw to be soldered.
Its was to small and it did not reaches the other edge, so I have use a tin aerpeace wire, the colored one, to join it to the + on the K750i PCB to the + of mic. (mic I took the K300i very small round mic)

I soldered the mic face down to the hole in the K750i PCB
I have used the base off the mic and soldered directly to the ground of BCP where the - of mic should be soldered. On the K750i PCB there is 3 Negative points. 2 points right behind where the resistor K1.2 should be soldered, and all around the hole where the voice goes thru. I have used the 2 points of negative to ground the mic

Read this info, analyse it good, and you will easely fix your K750i or W800 mic problem.

Thanks to all we give advise!
