sony ericsson w300i mic not working

Sunday, July 22, 2012 | 0 comments

Hai i am using the sony ericsson w300i for last two and the half years. Now i purchased the new phone samsung guru e2252 (dual sim and dual standby ). But i was very happy with my sony ericsson w300i since two years, so i have two sim cards and both are in samsung 2252. but in recent times i have faced some problem with my sony ericsson w300i. since this is the flap phone, i have changed its flex ribon two times. That's is the biggest problem of the flap phones, but this is destiny.

But now i am facing the new problem. the mic of my phone is creating bit problem.even you are calling to another person then you have shout harder to keep that persons alive , the mic of sony ericsson w300i is integrated with mother board. so can't not change the  mic easily . but i have heard some mic ways , jumper ways, by which we can change the mic of a phone easily with hard work. so i am uploading some pictures of my sony ericsso w300i, after the every picture i am telling you about the problem that i am facing and what i did at that time.

This is how i opened my phone , not a big problem

6t screw driver opened two close to speakers and 2 below the battery, thats looks fine.

now just make up lay down the mother board and stand rest of the part of the mobile , like in the picture , don't stretch the mother board it will harm the flex ribon.


I take out the mic it was very hard , i did carefully and you should , this is how now he looked.This is picture right before sholdring.




This is the picuture that i found on the internet , and this giving solution.

, This is now the real situation , i have purchased 3 mic and i fixed them to accordinaly + , - and after fixing the first mic, the volume of my mic loud, then for some reason the first mic was broken , then i puchased the second mic , when i fixed this the volume was very low and then after that attemp the mic did not work with second and third mic. now mic is not working , i am tired of sholdring

I did lot of shouldring and removed it , This may be the reason that places of plus and minues effected. The way that i am using the volume recording function of laptop for  testing the mic of the phone. The very frustrating thing is that you have to close the whole phone just with out  4 screw then turn on the phone and test the mic , if the mic is not working , then again you have to open the back panel and speaker cover.
 If you dont know anything about the mobile phone , then may be you should try another phone because the upper panel will always there with mother board , and of tried to remove the flex ribon jack , then you may lose you flex ribon(i tried once and lost ,my flex ribon).
 

WHAT SHOULD I DO?
please tell me way that i test the mic with out removing the battery

i need your suggestion advise , this post may be helpful for many other as well
thanks
