3100: No Speaker and Microphone at 900MHz - GSM-Forum

NobrakeS · 09-19-2005, 15:08

Hi to everybody who can offer a solution

I have 3 Nokias 3100 with no speaker and mic while serving at 900MHz Operator. The phone sends and receives calls but no sound at all: neither in mic, nor in speaker. I do not hear anybody and they do not hear me. Tested on several sims from different operators. No effect.

But If I put a sim from another Operator using 1800MHz - all is OK: both mic and speaker work.

RH-19 (3100), MCU 6.01, PM is OK(tried several versions).

Please, help! This is urgent.

Thanks.

hi m8,

i think reason for your problem can be your tx,rx not in order for 900mhz.
try to replace power amp first.post result.
goodluck.
