K700 no microphone-help pls - GSM-Forum

daneli · 02-26-2005, 22:07

Hi friends. I have SE K700 with damaged microphone circuit. The small metal IC near bottom connector is broken. Does anybody know solution to fix this problem without changing this IC. Maybe I need to short some points on the IC area. I don't know, I have no manual. Please help me with some photo.

Come on guys there must be solution
Have somebody try to bridge or bandage mic???

If you look the PCB from behind(the SYS conn is down). Then the MIC contacts are last 2 in the lowest row and other 2 are last 2 in the highest row. Hope this helps AND GOOD LUCK WITH BRODGING. O I forkgot to mention... if PCB is from the latest production then it is all LEAD FREE so be careful.
