Nokia 2710 No LCD Screen Display Backlight LED solution
If ever encountered a black or dark LCD Lcd display on nokia 2710, this problem is cause by the LED backlight failure or it doesnt light up.
This solution may help fix and repair Nokia 2710 No LCD Screen Display Backlight LED problem that result to a dark Lcd display on the LCD.
If this problem happens you may then first try to install a new replacement LCD Lcd to ensure that the LCD LEDs caused the problem or not. if the Back light LEDs still does not work, you may then proceed to hardware troubleshooting and used this solution below.
The solution above showed the LCD and keypad backlight LED driver circuit. this circuit holds and drive the LEDs to light up or works.
You may start to trace the LEDs positive ansd negative line paths from the LCD pin connector down to the components where it is being connected.
Check the LED driver IC supply voltage, this voltage has a rating value of 3.7 volts which feeds from the phones battery.
If all of the line paths and supply voltages were both fine, you may then proceed to replace the LED driver IC.Note: a damaged LED driver IC on nokia 2710 will also result to keypad backlight failure. Therefore if the keypad backlight is working and only the LCD display backlight does not work, this doesnt mean that the LED driver chip is faulty or damaged. This indicates the LED driver IC is still working and fine.

Nokia 2710 Mic mouthpiece microphone problem solution
Heres the solution for Nokia 2710 navigation edition when trying to fix a microphone problem issues. Its a failure on the hardware which there is no audio sound can be heard over the receivers earpiece speaker.
This solution simply shows the location of the components where you may to have a check or replace if found damaged. In Nokia 2710ne, the cell phone microphone is installed or mounted on the bottom side of the PCB board, and also all of its corresponding circuit components such as the filter coils or surface mount inductors, chip resistors and chip capacitor were also mounted near to it.
This also includes the circuit connection line paths (mic ways) for easy tracing procedures. The three lines paths corresponds to the polarity of the audio signals, the red line is for the positive, the blue line is for negative and the bright green lines correspond as the positive voltage bias of the microphone. If this voltage bias when cut or damaged it will also result to a poor audio signal level or no microphone audio signal.
