[help]s3 i9300 no mic, no gyroscope and now doest power on! (water damage) - GSM-Forum

phantomEVO · 02-17-2015, 14:55

so i have opened two thread for only one phone an i9300..so i think there is a little bit confusione. i write this thread to report all together the problem of this phone (fall in water). administrator can close old thread, thanks!

i've cleaned the motherboard and changed 4 corroded inductor, taking them from a motherboard of different phone with similar inductor (same size)

the phone boot!

but it has 3 problem: no microphone (in audio record there isn any sound) and no microphone in video recording (there is only a very bike noise like tv where there isn't signal)

the second problem is that camera menu buttons are all upside down, and when a take a picture, it is saved upside down

the third problem is that using secret menu, it tells me that gyroscope test fail!

i've done this fix

and solder it (taking from s-6500, u403)

than i've checked the voltage of u600

but the voltage of c601 drop to zero some secondo after i switch on the phone

then i've checked all voltage like service manual said

and they are all ok so i've rehot u205
but the worst thing is that now the phone doesn't power on anymore and it is not recognized from pc!!

i've checked all voltage

and it is all ok!!! now i don't know what to do please help me!!! could be the other u600 that i've soldered? because before soldering it, the phone power on!

Don't jump from one problem to other. Solve one problem from start to end, than go to next.
