i have a 3310 with no ear sound . mic and ringer are ok but no ear sound. the tracks from ear conectors to capaciror near cobba are ok. i changed the cobba but still the same. the resistance between conectors is about 1800. what could be the prob???? some ideas????

any help will be apriciated.
Thanks mates!!!!!!!!1

check the lines from speaker pads to the resistor arround the cobba ic, cobba change still no sound 99% broken tracks (compare the tracks with other33xx) .

check pin g5,g6 from hagar to f8,g8 cobba connection...

TechnicMan · 05-01-2005, 15:02

Check resistance of speacker (30Ohm),change speacker if bent or soiled.
1. Check connection between speackerpads on PCB & C124. if not ok, check R119/120.
Check resistance of speackerlines to ground, resistance of both lines should be > 0.5M
If fault persists, change COBBA N100. Note that it is necessary to realing RX/TX values & rewrite SIMlockdata after changing COBBA....

Hi, guy. Try my idea. I am sure you will learn more than "no sound" on 3310.

See the attachment

More info, refer to www.seichina.com

Ask them for some books.
