This solution may possibly help fix and repair a damaged Nokia 7230 that result to Insert Sim card problem issues. If the mobile handset device does not accept any kind of sim card and only shows insert sim card in the LCD Lcd display, you may refer to this solution below to trace and check certain components that might get damaged and result to insert sim card problem.
The solution above shows the connection of the sim card pin connector and its signal line paths through to the GAZOO IC.
You may need to ensure that SIM card pin connector is perfectly clean and free from any oxidation build up.
The SIM card supply voltage or VSIM is one particularly line paths that may need to check first for this line paths will easily open or cut especially if the nokia 7230 suffered water  damaged.
If the Sim voltage line is okay and you get a voltage reading on that area. You may then proceed to suspect that the GAZOO chip is faulty, reworking the chip might help fix and solve the Nokia 7230 insert SIM card problem.

This solution can be used as  a guide to fix or repair Nokia N97 microphone problem issues. A failure that no voice can be heard from the caller on the device.

This solution solution shows the components location of Nokia N97 microphone circuit that needs to be check if the problem occurs.
Repair tips:
Ensure to restore or flash the device firmware first before trying to calibrate hardware components.
If flash firmware updating  is already been done and nothing happens , you may then proceed to troubleshoot hardware components.
a) Trace and check the supply lines paths of the microphone module.
b) Check and or replace the resistors highlighted on solution above, the two resistors have 0 ohms resistance value while the other one has 100 ohms.
c) If all the resistors seems all working and or already replaced and the supply voltage is okay, you may then replace the digital microphone module.

For further troubleshooting Nokia N97 Microphone failure, there are instances that you may need to rework the audio IC(AVILMAS) and sometimes the problem lies on a faulty CPU IC (RAPIDO).

NOKIA N73 MICROPHONE AND EARPIECE PROBLEM: THE PHOTO CONTAINS NOKIA N73 MIC AND EARPIECE PROBLEM REPAIRING SOLUTION.

If ever trying to fix Nokia X6 touch Lcd failure issues and youll do replacing the touch plate module, trying to calibrate the touch Lcd setting but unresponsive and restoring, upgrading and flashing the device firmware but nothing happens, the problem still exist and the touch Lcd left unresponsive.
This sometimes happens if the device suffered due to a wet damaged, heavily dropped and any related damaged accidentally done by the user. In this case only a hardware repair may only help solved the problem.
This solution below show the Nokia X6 PCB board components that holds and control the touch Lcd panel to work.

The solution above showed  a Touch Accelerometer chip that   used to sense orientation,  detect direction in multi-access direction of the Touch  Plate module. If the chip is damaged the touch Lcd will not work and remains unresponsive. This chip needs a DC supply voltage of 2.78 volts in this designed on Nokia X6 and also. The 2.78 Dc volts is also feeds and supply the touch plate module.
You may check this supply voltage first before trying to rework, re-ball or replacing the touch accelerometer  chip.

Heres a solution that can be used to fix and repair Nokia X6 Display problem issues like white Lcd, blue Lcd, blank Lcd, garbled and saturated Lcd displays.. This solution may help if having a LCD display problems and already tried to upgrade or restore the device  firmware and  replaced it with a new LCD module replacements but the problem  still exists. There are two voltage supply that also need to the LCD display to work, the 1.8 volts and 2.78 volts.The solution above alao shows particular components that needs to check and replace if found faulty or damaged like the Display  ESD-EMI filter IC.

If those supply voltages seems to be okay and the LCD display ESD-EMI filter IC is working well and already been checked and replaced the solution below shows the next components that also needs to check, rework or replace. On Nokia X6 there is a display controller IC that is being used and connected on the LCD display circuit.
If the LCD display controller chip become faulty or damaged this will also result to a display problem issues on Nokia X6. But before trying to reflow, rework or replaced you  need to check first the three filter coils connected near to it and trace each line paths to the LCD pin connector.
