Nokia 3710 fold Earpiece Speaker Failure Solution
If the there is no sound can be heard on Nokia 3710 earpiece speaker, this problem may possibly caused by a faulty speaker, a corrupted flash firmware, a damaged flex wire, oxidation build up due to wet damaged, weak contact terminal pads and possible damaged components within the PCB board circuit.
This solution below can be used for further troubleshooting if already doing a check up and found out that the speaker is okay, the flex wire is good and working and or already tried installing a new replacement, the PCb board is already cleaned.
The components highlighted on the solution above is mounted or located near the flex pin connector and the application processor chip. These components are composed of a filter coils, resistors and an ESD protection chip. These is where the audio signal flow across this components which is feeds from the Audio IC (GAZOO).
You may check each of these components and replace if found damaged to possibly fix Nokia 3710 earpiece speaker problem.

Nokia 2710ne camera hardware failure problem repair solution
This solution shows the camera module circuit of nokia 2710 navigation edition. If the camera failed to initiate, this solution might help fix and repair the problem. If already tried to restore its firmware but the problem still exists, this solution shows the tracks of the Camera module supply voltages that needs to check before attempting to replace the camera module assembly.
There are three power supply voltages that makes the camera module works and operate if one of these voltage were missing the camera will not function, and it shows camera hardware failure, camera on standby and either no reactions or indication at all.
A Camera on standby mode may fix by restoring its firmware. If an empty or black screen showed on the LCD display screen, the problem may lies on the camera module itself, replacing it will possibly solve the problem. So first ensure that the firmware is secured before proceeding to hardware troubleshooting.

Nokia X6 Send E60 and END keypad keys failure solution
If the Send, E60 and End key button keys failed to respond on Nokia X6, and you already tried to restore, reset, flash and update the device firmware but nothing happens.
Keypad keys malfunction on Nokia X6 may also possibly caused by a faulty keypad flex, cleaning or by replacing it will help solved the problem.
If after replacing and ensuring that the flex is okay but the keys still unresponsive, you may then consider that the problem lies on a faulty keypad circuits hardware components on the PCB board. This solution below will tell us which components holds and controls the keypad keys to function or work.
Check the keypad pin connector first ensure that it is free from dirt and oxidation.
From the keypad pin connector there are three line filter coils located near to it, have a check on this components and replace if found damaged.
From the keypad filter coils the lines is feeds to a keypad filtering chip or keypad IC, you may then check this chip, trace its line paths and replace if found damaged.
The I/0 Expander Chip is the keypad controller components, which holds and control the keypads including the Touch Control Module. You may also rework or replace this chip for further harder keypad problem repair on Nokia X6.
