Nokia C2-03, C2-06, C2-08 Not Charging Problem Solution

Now working on with the new solution for Nokia C2-03, C2-06 and C2-08 with Dual SIM phone capability. This time we will tackle first the charging circuit in case handling into troubleshooting a not charging problem, due to wet damaged or any possible causes.

The highlighted components below are the basic components of Nokia C2-03, C2-06 and C2-08 charging circuit just like any other Nokia previous PCB designs, the only thing always makes any different is the location of those particular components location being mounted on the PCB board.  


And here's how to fix a not charging problem for Nokia C2-03, C2-06 and C2-08: 
1) Ensure and check first the wall charger, battery and battery connectors for possible damaged. 
2) Check the charging pin connector (DC jack), clean it including the terminal contact pads. Replace if necessary.
3) Check the charger voltage protection components such as the fuse, diode, filter coil and capacitors. Replace if found damaged. 
4) Trace the charger voltage line paths for possible open circuit or cut-off lines. 
5) Check the charging voltage transistor switching circuits, including the 0.15 ohms fusible resistor.

Nokia C2-03, C2-06, C2-08 Memory Not Detected Solution (MMC IC Jumper Tracks/Ways)

Here's another solution that covers for Nokia C2-03, C2-06, C2-08 memory card not detected problem cause by wet damaged or any possible causes like oxidation build ups etc.The Nokia C2-03, C2-06 and C2-08 slider phone has designed with a built in ESD and EMI filter chip that protects the system circuit if there's something went wrong from the memory card. In most Nokia PCB design this chips were also found and called as "MMC filter IC". So, in troubleshooting Memory card not detected problem mostly it can be fix by replacing the said MMC IC.

Here's some hints on how to fix Nokia C2-03, Nokia C2-06 or Nokia C2-08 Dual SIM card, slider phone with touch and type features.
1) If memory card is not detected error shows, try to use another working memory card. The memory card might be corrupt  or already damaged.
2) Check for possible damaged and or clean the memory card connector pins and its surroundings components on the PCB board. 
3) Check the firmware, reflash, restore or update to latest version if necessary.
4) Check, resolder, rework or replace the memory card filter chip (MMC filter IC)

Nokia C2-03 Keypad Light LED Problem Solution

Here's the some hints that may preferably help fix in troubleshooting Nokia C2-03 keypad back light failure. 

1. Check the whole area and surrounding components for the keypad white LED for possible damaged, cracks, oxidation etc. Clean it first if necessary.
2. Check both of the two LED's using a multimeter. Replaced if already damaged.
3. If the LED's light are still working check the (VBAT 3.7V) battery voltage line paths.

4. Check each of the LED's positive and negative connections.
5. Check the  connected resistors and coils, re-solder or replace if damaged
6. Check the LED driver transistors. Re-work or replace if necessary.

The Nokia C2-03 backlight driver components.
In this figure shows the detailed components or parts that is called "LED driver circuit".
This will cause the display backlight loss if one of these components being damaged and or each of its connection line paths breakdowns. This circuit may only damaged if the device suffered wet or water damaged that resulted into oxidation build ups and then caused a short or open circuit.

So, check out these parts:
- Clean these components surface if necessary.
- Check each of the filter coils first. Replace if found damaged.
-  Trace the VLED and VBAT_BB connection line paths - point to point to the corresponding capacitors, filter coils and including down to the Flex pin connector.
