Nokia E5 Keypad Light LED Jumper Ways
[You must be registered and logged in to see this image.]
Troubleshooting hints for Nokia E5 not working keypad backlight LED problem:
1. Check a certain LED's that won't light up using a multimeter. The white LED bulb are connected in parallel. Replace if found damaged.
2. Trace each certain connection line paths for possible cut off or open circuit.
3. Check the 3.7v VBAT (battery voltage) across the inductor coil.
4. Check/replace the inductor coil.
5. Check/replace the diode.
6. The LED's negative supply voltage is feed from the GAZOO IC.
There is a possibilty if the GAZOO chip is faulty, it will result to keypad light problem.
Reworking it might only fix the problem or replace if necessary.

Nokia E5 Insert Sim Card Error Problem Solution
[You must be registered and logged in to see this image.]
In Nokia E5 the sim card operational circuit is controlled by the GAZOO IC. You may first check, clean the SIM card connector pins, then try to replace the highlighted components such as the capacitors and resistors.
Check the VSIM ( sim card supply voltage) and ground pin line paths.
If all of the said components is okay, but the problem continues. The problem may possibly lies on a GAZOO chip. Reheating or reworking it might only fix the problem. And then replace if necessary.

Nokia E5 LCD Screen Display Problem Solution
[You must be registered and logged in to see this image.]
The solution above shows the connection line paths of the display signals from the ESD-EMI filter IC down to the LCD pin connector. Which you can use to trace the the LCD displays corresponding line paths across to that circuit. You may first check the LCD's supply voltages on the upper components of the PCB board, also check or replace the resistors and capacitors. Then if the two supply voltages is okay. Try to replace the Display filter IC alternately.
