Earpiece and Ringer Speaker Solution for Nokia 1800 and Nokia 1616


Here's the repair solution to solve and fix nokia 1800 and nokia 1616 Earpiece and Loud Speaker (Ringer/buzzer) failure. In nokia 1800 and nokia 1616 the earpiece and ringer circuit have been combined and connected to a single speaker unlike the old types which  have both different speaker in each circuit.

The  below solution picture shows the line paths and layout of components for the Earpiece Speaker.You may trace all of those corresponding components if having trouble with the earpiece or Earpiece Audio sound problem. The positive and negative audio signal which flow across into four coils, a chip resistor 4.6 ohms and an EMI filter chip before it being feeds to the Speaker terminal pads and so on to the speaker.

The two remaining components are chip resistors, this resistors are fusible resistors with has a zero ohms value. Both positive and negative Audio signals also flow into the two filter coils and the emi filter chip then feeds trough to the speaker.

All those components are very easy to check and you may find a replacement on it if found busted or damaged. If all of its corresponding components were already replace and making sure that all of it working perfectly okay but the problem still exists and no audio sound can be heard over the speaker, we may now consider that the problem lies on the line paths between the main IC or the IC itself is being damaged. connections.

The last solution solution for this is to reflow, rework the main IC component. Be sure to check the line paths of corresponding solder ball bumps of the IC component which holds the earpiece or the  ringer loud speaker, after reballing it and inplacing it back.
Just be careful and have a good heat temperature and air flow control using you reworking station in handling the main IC module
