Nokia 2630 No Network Service Found Solution
Heres a revived solution for Nokia 2630 No network service found problem. This problem may happens if the device suffered water damaged and or heavily dropped. The solution below shows the Nokia 2630 RF (radio frequency) circuit. This holds as the transceivers of the data into the airwaves during transmission, and if this circuit will breakdown or being damaged it will result to NO NETWORK Signal problem issues.
Repair Tips:
Ensure that the device firmware is okay or successfully restored or flashed.
Try to upgrade into higher version and write a good PM files.
IF the firmware calibration already done but seems nothing happens you may proceed to trace, check or replace the corresponding components showed on the solution above. Make sure that the PCB board condition is still stable and not like bended or some damaged spots. Check also if there is oxidation build up, clean it first before you may proceed.
First check the PA supply voltage, this voltage is came from the battery B+ terminal and you can trace it between capacitors showed on the solution above.
If the voltage line paths is okay, try to replaced the PA (power amplifier).
Then if nothing happens, you may then try to rework or replaced the RF transceiver chip.
If all the chip is already been replaced but the problem still exists, try to replace the voltage controlled clock crystal oscillator.

Nokia 5320 xpressmusic No network Signal problem hardware repair solution
Heres the solution that may possibly help fix and repair nokia 5320 xpressmusic No network signal problem issues. Before you may proceed to use this solution, ensure that the device firmware is okay, restored and already flashed and or updated. This solution may only works if the device suffered a water damaged or heavily dropped by the user.Repair Hints:Check the battery voltage across to the components highlighted on the solution below. These are filter coils and you need to have a voltage reading in this components about 3.7 volts., It is connected directly to the battery positive terminal. Replaced filter coils if found damaged, apply a jumper wire if found the supply voltage line is open or cut.
Check the voltages in these components highlighted in below solution, these are the output voltages from the voltage regulator chips that supplies to the RF IC and RF Power Amplifier chip. If there is no voltage readings in these components, check and replace the corresponding Voltage regulator chip.
1)Rework or replace the Power amplifier PA IC,
2) Replace the Voltage controlled crystal clock oscillator
3) Rework the RF IC or replace if necessary
Hope this helps solved to fix or repair a damaged Nokia 5320 No network problem issues.

gfive l228 network solution
Gfive l228 is very famous in this time in bangladesh.This Mobile phone famous for loud sound.However,now I discuss how to repair gfive l228 network problem or no service.
How to do this work : Open your phone with sim and see on the display.If you see no service or no network then first restore factory setting using security code 1234 and see result.if you see result same then check ant and ant ways if damage this repair it, if this are ok but problem same then replace red mark parts.this is network ic (pa).
