    Hints in troubleshooting Nokia 500 Earpiece Speaker

    1. Start to check with Speaker assembly, it is located at the top of the board behind the LCD screen.
    2. Check for possible corrosion build ups, speaker terminal bending.
    Clean it including the speaker terminal pads or aligned it again if
    either the connection might be weak.
    3. Check the speaker using a multimeter. Set the tester to X1 and check
    if there is crackling sound can be heard and the tester responds. If no
    indication of anything, the speaker is already burned out or damaged.
    Replace it at once.
    4. If the speaker is okay, and still there is no sound can be heard, check the firmware. Update it or do re-flash.
    5. If the problem still exists, the possible faulty is the GAZOO ASIC
    chip. The only solution for that is to rework or replace it if necessary
    and that's need a good soldering skills to do it.
    Warning: If you do not have much
    skills on how to to re-ball or install a BGA chip, just leave it to the
    experts. Attempting to touch that chip without expertise will cause the
    phone dead in no time. [/center]
