mccm · 04-10-2010, 07:56

set water damaged,after cleans phone working fine except no sound as in headset,mic,earpieces or speaker when making calls,incoming calls phone ringing so not the speaker or earpieces problems,most probably hardware faulty.
Anyone have experiencing this fault?

Thanks in advance

it must be from power supply control ic smp3i(infinion).

please check it for liquid damage.

Make sure the mute switch is not set to off. Sometimes we forget simple things and search at the wrong place. Just and idea more.

just change earpeace strip tested by me,,,,,

be carefull while remoing display

mccm · 04-10-2010, 11:13

not all the above mention logic device ,test the board on a working set still no earpieces,mic or speaker sound when making calls,but can play out songs?

when restore from itunes ,it never congratulate about sim activation,only the set shows device are activated.

could it be software problems?

maybe you need to check speaker line, speaker? before restore!

Ear piece strip Mounted together with LCD ,as mention I had try on a complete working set,is the main board problems.
All speakers and earpiece line not broken or under value.
Some chips are control audio ,don't know which?
