6510 startup ok, then handsfree mode - GSM-Forum

fontelense · 08-11-2004, 11:27

When I turn on the phone, it has sound in speaker, but two seconds later it breaks and goes to handsfree mode. When handsfree is inserted, there is no sound on it either.
Does anyone have a clue on what to do to repair this?
I already changed bottom connector, checked path between "headint" and R155, R155 and C157, all ok. I also did a reflow on UEM, still the same.

Best regards

Check the other track (external ear-P) L104 , R165 , also if the attached capacitors have any short to Ground .

Thank you, problem is solved. Link from L104 to the socket switch was broken, so the switch was not working at all, always in handsfree mode an even so no sound in handsfree.

Best regards
