Hi Wondering if you clever people could assist I have a iphone 5c that has no sound from the ear speaker, i have replaced the front camera flex as well as the little black speaker, but i still cannot get any sound from the ear speaker. Is there a chip or some other part on the board that controls this, or some obvious software setting Thank you all Update (02/25/2017) Thank you all for your repsonse So ive tried the following

  1. Tried 2 new ear speakers
  2. Tried 2 new flexes
  3. Checked connector All ok no obvious issues, is there a chip or something on the board that may be causing this issue?. If i try a factory reset will that work? Regards Ali

Most likely, if you have replaced the front camera flex, as well as the speaker itself, it is either misaligned on the contacts (make sure that the contacts on the black speaker piece are aligned on the camera flex cable), misaligned on the logic board (check for misaligned flex cables on the logic board), or a pin has been broken on the logic board (disconnect the flexes for the display and camera, and check for any broken or damaged pins on the board). Other causes are far less likely, but could include: Defective speakerDefective Front Camera FlexOther hardware or software issues
