M35 slow ring

[nnarta]

I have a problem with M35. Buzzer rings very slowly. Buzzer ok, pcb is clean, all components near bottom connector are ok, software reflashed...<br />Any ideas?

I'm not sure if there is a time crystal on a M35. But solved many problems with nokia slow ringing tones by changing time crystal.

Sorry, I made the mistake!<br />I have low, quiet ring (instead of slow ring)<br /> <img src="smile.gif" border="0"> <br />Any ideas?

NNarta...if it helps any..on c25 this was caused many times by a coil damaged by opening housing incorrectly.M35...maybe??? <img src="wink.gif" border="0">

I solved many on ericsson phones by changing small ic with three legs, that is near the buzzer. it must be a problem and nothing else..

Try to replace small microcircuit below keypad. The most right microcircuit which control buzzer and Led.

Hope help

Yes, BBand is right, there is a small microcircuit (6 legs) and some of it marked DOB located at the bottom of the keypad, this microcircuit controlling the lamp and the buzzer activity, replacing it may correct ur problem

Everything has been replaced (crystall, 6-pin element, software). Result is zero! M35 has no coil as C25. I gave phone back to the client. <img src="confused.gif" border="0">
