Nokia 5220 Xpressmusic Charger No Response Not Charging Solution
If ever encountered a Nokia 5220 Xpressmusic that shows no response or indication on the LCD display
when a good and working charger is being plug-in. This trouble may cause by a damaged charging pin connector or an oxidated charging pin terminal contact pads.
Replacing and or by cleaning it will definitely fix the problem.
In some cases like a wet damaged Nokia 5220 there are certain components that may also get damaged like the charging fuse and or the protection diode. The solution below shows where this certain components being mounted or located on Nokia 5220 PCB board.
You may check those components showed on the solution above and replace if found damaged.
You may start to check the fuse if already busted or cut-off, then down to the filter coil and the chip diode.
A shorted diode may cause the fuse to blown or breakdown. Replace it if its already shorted.

nokia 5320xm Ringer and Hands Free Speaker No sound solution
This is the solution for nokia 5320 xpressmusic Ringer and hands free speaker failed to have an audio sounds output when the hands free mode is activated and or no ringtones can be heard. The solution below shows the location of particular components that needs to be check or then by replace if found damaged or faulty.
After ensuring that the speaker is working okay but the problem still exists, locate the corresponding components showed on the solution above, these components are filter coils. You may need to rework the audio IC (AVILMA) for further deeper troubleshhoting and also by tracing the each earpiece line paths from the avilma solder ball bumps across to each filter coils and to the earpiece speaker terminal pads.

Nokia X3 No LCD and keypad backlight LED solution
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.

Nokia 3710fold Ringer Hands Free Speaker No Sounds Solution
This solution may useful and help fix or repair Nokia 3710 fold ringer and hands free mode loud speaker speaker that no audible sounds can be heard on the device.
If encountered and tried to fix this problem you may start to check the speaker, replace if it is already damaged, cleaned up the PCB board contact pads for the speaker terminals.
If already been installing a new speaker or cleaned up the terminal contact pads but still there is no ringtone or an MP3 music sound can be heard on it when being played.
This simple solution shows the left and right ringer (IHF)hands free speaker components circuit on nokia 3710 fold PCB board, that needs to check for further troubleshooting.
IF only one channel is having a problem you may only trace and check the components associated or connected with it. The left channel speaker is which is only connected within the main PCB board, while right speaker channel is the one connected across the flexible wire.
Troubleshooting for the right speaker needs also to check flex cable first before checking the connected components on it. The left speakers connected components are mounted and located near the bottom side of the PCB board.
Checking this components were a lot easier for these are composed of a filter coils and an ESD protection components. Just replace if found one of these components damaged to solved and fix Nokia 3710 fold Hands free and ringtones speaker no sounds problem.
