iPhone 4 no sound during call – is this iphone problem , and strang hardware issue

On January 23, 2015, Posted by , In iPhone, With Comments Off on iPhone 4 no sound during call – is this iphone problem , and strang hardware issue

Hi,


I have an iPhone 4 laying arround and it has the following problem :

  • no sound during phone calls ( also on speaker )
  • mic during phone calls

How can i fix this ? This phone was dropped from 2.5M height.

Do i want to replace / reflow Audio IC 338S0589 ?

If i want to replace it what temperature can i use the best ?

No Comment so far:

    And is 338S0589 the right one or do i have to replace other one?

    No want to replace, just desolder, reball, and solder it back.

    Be careful, first you have to remove the resin, and careful too when you lift the chip, to avoid stripped pads. If you never done it, give it to a professional
