The solution below shows us where and what particular components we need to check in troubleshooting nokia X3 camera problem.

Nokia X3 Camera Operation Failed Solution

If encountered such camera problem, you may need to check the supply voltages of the camera module first, if this supply voltages is open or cut, just find a way to reconnect the line paths.
Try also to replace or install a new Camera Module.
If these camera supply voltages is not present or can't be read using a multimeter there is a possibility that the Pearl IC is faulty, and also if all the supply voltage line paths and camera module is okay, you may need to rework the pearl IC or replace if necessary.

Nokia X3 No Network Signal Solution

Here's the solution for nokia X3 No network signal problem. This solution can be only used if the said device is already been restored or already do flashing the flash firmware but still the problem still exists.

The solution below shows the RF circuit on Nokia X3 PCB board layout.
You may need to check, rework or replace these components for further no network signal problem troubleshooting.

Nokia X3 No Network Signal Solution

In troubleshooting network problem  manually, check the whole RF circuit components first, ensure that it is cleaned free from oxidation build up due to water or wet damaged.
You may start to work with the RF Power amplifier (PA).
Try to replace it with new replacement one but before that check the RF supply voltage first which came from the battery voltage 3.7 volts.
If the power amplifier has been already replaced but nothing happens, you may then try to rework the RF chip, or replace it if necessary.
There are also some possibilities that the signal lost is caused by a faulty or damaged oscillator and RF filters.

Check the line paths of Nokia X3 Camera, Volume Up and Volume Down terminal line paths where it is being connected to certain numeric keys, in these procedure you can determine which and where certain spots you can apply a jumper wire when needed or when the button switch terminal solder pads is already lifted or damaged.

Nokia X5-01 Blank, Blue, Garbled LCD Screen Display Problem Solution

Here's a full troubleshooting guide to fix and repair Nokia x5-01 display problem issues.

This may help in troubleshooting display problems such as blank or empty screen, blue screen, white screen, garbled and saturated screen displays.

If ever encountered this kind of display problem you must first try to install a new replacement LCD module and then restore or flash the device flash firmware again.
Once the installing a new LCD screen and flashing the phones firmware but the problem still exists, you may then check the components showed on the solution below for it is where display problem occurred when these components being damaged or faulty.

Nokia X5-01 Display Filter IC solder ball bumps connection tracks

In Nokia X5-01, there are two ESD-EMI filter chip is being used in the display circuit, mounted or located beneath the metal shielding just besides the LCD pin connector.
You may then check this two display filter IC and or trace each line paths for possible open or cut-off lines.
Replacing a damaged Display Filter IC may only help solved and fix nokia X5-01 display problem that is not caused by the LCD module and interrupted flash firmware

Nokia X5-01 Menu,Send, Power ON/OFF and Navigation keypad flex solution

This is a solution for nokia X5-01 upper keypad flex that is not working or functioning. If encountered a problem like the Send, Music, S60-L, Soft left, Soft right, Left, Right, Up, Down, Select and the End / power button keys that is not working this solution may possibly help fix the problem.

The following solution shows the  flex keypad connection line paths for easy tracing and check up procedures. This can be also used to locate where and which components needs to be check and or where can apply and put a jumper when there's a line being cut or open due to wet or water damaged.

In troubleshooting upper keypads you must first visually check the flex assembly for possible damaged, scratched or cut. A damaged flexible cable wire assembly needs to be replaced a new replacement spare.
However, if there is only one key that is not working except the END/POWER key, you may refer this solution below for it shows the connection line paths of the upper keypad keys board on the flex assembly.

Nokia X5-01 Upper Keypad Flex Line Connection  Tracks

The Send, Music, S60-L, Soft left, Soft right, Left, Right, Up, Down, Select and the End / power button keys connection used filter coils that is mounted or located at the back side of flex. If only one key is not working except the power key , you may first trace the corresponding line paths and filter coil connected to it, then just replace or mend to reconnect the open or cut line paths.  If there is two or more keys that is not working you may suspect that the flex is already damaged it is because the solution shows that there are minimum of two certain keys shared in one line paths except the power on/off button.

The next solution below can be used for further upper keypad keys breakdown or failure. This solution can be used if the keypad flex is already been tried installing a new replacement flex ribbon wire, for it shows the complete connection line paths from the flex pin connector to the keypad filter IC solder ball bumps.
