Nokia X2-01 Bluetooth Hardware Problem Solution

Nokia X2-01 Bluetooth Hardware Problem Solution

ere's a solution if having a Bluetooth function failure on Nokia X2-01 due to wet damaged or accidentally dropped. The

solution below shows the key components of bluetooth on the device. Bluetooth may not often damaged, for it is properly

shielded and mounted toughly on the PCB board. But sometimes it also goes wrong specially when the device is getting wet by

a any liquid or just have being accidentally dropped.

To fix Bluetooh X2-01 problem you may first check the device firmware. and try to restore it, flash or update it. If the

device suffered wet damaged, you may first take a check up on the bluetooth components, clean it first, by using a liquid

cleaner. Check the antenna connection pads and connector, if the connection is weak it will also result to connection error

and malfunction..

Check and trace the supply voltages to the bluetooth module... If the voltages were okay, then you may proceed to re-working

and replacement procedure.

Nokia X2-01 Camera Hardware Failure Problem Solution

Nokia X2-01 Camera Hardware Failure Problem Solution

Here's the solution for Nokia X2-01 if damaged and the camera goes wrong and it doesn't work. This solution may work for

hardware problem issues and you already ensure that the firmware is already been re-installed or flash/update, but the

problem still exists.

Refer to the solution below have a check up on highlighted components, for it holds the camera connection line paths. You

may also then check and trace the camera supply voltages (VCAM 1.8V and 2.8V). Mostly, if these voltages are missing it

will result to camera failure situation.

You may also check the camera module holder for possible damaged. Clean, re-solder it if necessary. Sometimes an oxidation

build up due to wet or water damaged may cause the problem to exist.

Nokia X2-01 MIC microphone problem Jumper Ways/Tracks Solution

Nokia X2-01 MIC microphone problem Jumper Ways/Tracks Solution

Here's the solution to help fix and solved a not working microphone or MIC on Nokia X2-01 handsets.
The solution provides the detailed info of how the built in microphone on Nokia X2-01 PCb board were being connected to other components. It may help for to easily track down and locate the problem if the said microphone failed to work.

The Nokia X2-01 used an ordinary two pin microphone that is mounted or attached at the lower part of the PCB board, unlike other newly released device that uses a five pin digital microphone. Troubleshooting this kind of microphone is a little bit easier.

To begin troubleshooting , you may first inspect the whole microphone surroundings or connected components. Clean it if there is an oxidation build up occurs. You can check the microphone by using a multimeter. The connected components which are labeled according to their desired values are also a big help. You may also check and trace the connection line paths from component to component such as capacitors, resistors and filter coils.

Nokia X2-01 Not Charging Problem Jumper Ways/Tracks Solution

Nokia X2-01 Not Charging Problem Jumper Ways/Tracks Solution

Here's the solution for Nokia X2-01 if ever encountered a not charging problem.
The solution below provides the connection line paths of the charging circuit.

To fix the problem, you may first ensure that the wall charger you are using is properly working and the battery is not totally drained. Continue by checking the charging pin connector or DC jack connector, visually check it for possible damaged. Clean the PCB board charging pads and battery connector. If the problem still occurs proceed to components troubleshooting.

First check the fuse if open or damaged, second check the diode if shorted. Check the 330hms resistor near the power IC. Re-solder or replace if damaged. Trace the VCHARGE (charging voltage) line paths and the ground of the charging pads.

If the procedures above doesn't solved the charging problem, the possible faulty is the power IC. Rework or replace if necessary.
