Sony J70 no speaker - GSM-Forum

psych0 · 05-27-2003, 09:17

I have a Sony J70 with no speaker, however the speaker itself works great in a Nokia phone. The loudspeaker and the headset are OK. The speaker is not dumb fully because I hear that little gsm noise but there is not any voice. I downloaded the service manual but I can not figure anything out because the manual is not as detailed as the Nokia sevice manual and I am not a professional too.
So, can you help me repairing this unit?
