Heres a solution that may possibly help fix and repair Nokia X3 Failure of LED backlight  on keypad and LCD screen display. This solution completely shows the lines paths and particular components that may need to check and replace if the LED backlight failed to light up.




There is a fusible resistor is been connected to the LED backlight circuit in case a short circuit occurred if the device is being damaged by a liquid (Wet Damaged). See solution above marked with number 1.
That resistor is the one feeds the power supply from the phones battery.
If that resistor is open both keypad and LCD display LEDs will not light up for it is the main LED supplying positive voltage.
The negative current or voltage has two circuits, one for the LCD (marked with number 4) and the other one is for the keypads (marked with number 3).
You may check / replace each particular corresponding  connected components highlighted on the picture for further troubleshooting.

This solution shows the connection of the Nokia 2710 navigation edition keypad connections from the keypad matrix flex through to the keypad pin connector and  keypad filter ICs.

Bluetooth, Wireless LAN and GPS connection  problem can be cause by a firmware failure and can be easily be fix by restoring, updating or flashing the phones firmware again. But after doing any firmware repair and the problem still exists the problem may certainly lies on the hardware components failures.

This solution below  may possibly useful and help fix and repair Nokia X6 Bluetooth, WLAN and GPS problem issues for it shows the Bluetooh, WLAN and GPS component circuit.




Repair Hints: Ensure that the firmware of the device is successfully calibrated, upgraded and restored.
1) Check all corresponding supply voltages in the circuit
2) Check the RF buffer clock  feeds from the RF circuit
3) Check the Bluetooth and WLAN antenna
4) Rework the Bluetooth IC first,  the WLAN will not work if the Bluetooth IC is faulty.

Heres the full and complete solution for Nokia 2690 Keypad line tracks and keypad filter IC jumper ways including the power on-off key connection. This solution below may possibly help fix and repair a certain keypad malfunction that stop responding on a damaged Nokia 2690 cell phones.
