Thread: iPhone 3G housing re-assembled - no speaker, no proximity

  1. #1
    Default iPhone 3G housing re-assembled - no speaker, no proximity
    I recently replaced the housing on my iPhone 3g in the effort to make it more valuable on eBay (not worth the time and money spent).

    Now the speaker and the proximity sensor do not work

    Display, touchscreen, mic, headphone jack, etc all work fine.

    Any ideas on what's wrong?

    I think it might have something to do with cable 3 (but that doesn't explain the speaker).

    do you mean the speaker or the earpiece?

    ribbon 3 controls the proximity sensor and the earpiece. You either damaged it or didn't plug in in correctly.

    I did the same thing tried to force it in a little and crinked it. hopefully you just didn't connect it right.

    I agree with tag8402. The connector labled 3 is either damaged or not plugged in.

    Earpiece is fine; made a test call and I could hear everything and they could hear me.

    Definitely the loud speaker.

    Interesting, so the sensor flex controls the earpiece ... when I disassembled it I didn't realised that cable 3 had a lock so I probably damaged it.

    How hard is it to replace the sensor flex cable? And can I just get one off eBay?

    What controls the loud speaker?
