Nokia 6700 classic LCD backlight LED not working solution
This solution covers for Nokia 6700 classic Backlight LED not working on the LCD Lcd display that result to a dark or black Lcd LCD display.
You may first try to install a new LCD Lcd module before applying or using this solution below.
If the LCD Lcd is already tried installing a new one but still the backlight LED still not working or unable to light up. You may then need to trace, check and or replace the components showed on the solution above.
There is a BVAT voltage line that supplies to the LED driver IC and you can check this voltage about 3.7 volts which is came from the battery positive terminal. and came way across to the two filter coils before it feeds in to the LED driver IC.
If the the voltage supply line is okay, remove the LED driver IC and trace each corresponding solder ball terminal line paths through to the pin connector and VBAT voltage line filter coils.
Rework and clean the solder ball terminal pads.
Replace the LED driver chip if the problem unsolved.

Nokia X3 keypad problem full solution
Heres a full solution of Nokia X6 keypad problem and failure. This solution shows the complete line tracks for easy tracing particular keys that stop responding including the camera and volume control switches button.
Each key were group in one line of connection, each connection is filtered by an ESD filter IC. The solution above shows how each certain keys are being connected to the keypad filter IC. There are three keys commonly connected together in one line of connection, therefore if only one or two key is not working, you may consider that the problem lies only on an open path of connection. If there are three and above keys does not work you may considered that the keypad ESD filter is damaged or faulty.
