Nokia 1800 and Nokia 1616 Insert Sim Card Problem Solutions
Heres a complete repair guide to fix Nokia 1800 and Nokia 1616 Insert Sim Card problem issues. This solution shows the complete line paths of the SIM card circuit which we can used for easy troubleshooting procedures, including its connection to the IC components solder ball bumps.
The Sim card circuit of Nokia 1616 and Nokia 1800 used an EMI filter chip for the circuit protection.
This EMI filter IC can be damaged if an excessive electromagnetic interference or electrostatic discharge interfere with the circuit. The Vsim which is the voltage being supplied to the sim card to make it work also cause the problem if being cut or damaged, this voltage range from 1.8 to 2.4 volts, the voltage varies according to the type of SIM card.
Repair hints for Insert SIM card Problem repair procedures:
1. You may check the circuit surroundings first and see to it that it is free from dirt, foreign object and corrosion, a corroded components may also cause the problem, clean it first as necessary.
2. You may start to check the VSIM line paths continuity by using a multimeter, start from the VSIM capacitor through to the SIM card pin connector, to check if that said line is okay.
3. Check the ground line of the sim card pin connector, If the ground line is cut it also cause the problem.
4. Remove the EMI filter chip if the above check up is okay, check the EMI filter IC internal line paths, from solder bumps; A2 and A3 are the line for the the SIM data and the resistance value is 100ohms, B1 and B3 SIM reset, the resistance value is 100 ohms also and then C1 and C3 for the SIM clock signals which has a resistance of 47 ohms. Replace it if found busted or damaged, you can easily find a replacement for it in other non working Nokia cell phone models PCB board that has an EMI filter IC also, just look for the solder bumps configuration if its same.
5. This part may need an adequate experience and extra care to handle with or you may end up killing the phone, if you are a beginner mobile phone techie you may need to ask assistance to your head tech or a senior and most experience one technician before doing this procedure.
Now if all the above does not solve the problem, you may need to reflow, rework, remove the main IC labeled X-gold 110, then check the solder bumps continuity through to the SIM pin connectors, then reball it and in-place it back.

Nokia 1800 and Nokia 1616 Power ON OFF switch Key Line paths for Nokia working solution
Heres the solution to repair Nokia 1616 and Nokia 1800 power ON/OFF switch problem.
This problem may cause the device unable to power up when hitting the power key. The problem may easily configured if the power ON and OFF switch key has no response, but the device is not totally dead for it shows a charging indication when you charge it up. Now, this solution simply shows the line paths (ON OFF ways)of the power key.![nokia]()
Hints for repair: when the device will unable to power up when hitting the power key button but it shows charging indication when you plug-in the battery charger, the problem may possibly lies on the power key line paths. But before tracing the line paths, you must see to it that the keypad membrane is perfectly clean and free from dirt, corrosion and oxidation.
You can check the power ON/OFF voltage to the inner core of the switch key terminal pads, this voltage may range approximately from 1to 3 volts. If there is no voltage reading you get on that spot, locate and trace the test spots for the power switch, see the picture guide above, it is located just near the keypad LED. Make a continuity check by using a multimeter to those corresponding spots indicated on the picture guide, from the power key pads through to each corresponding component. The outer core is connected to a chip capacitor located near the clock crystal oscillator.
