Nokia 2720 fold Volume UP(+) and Volume Down(-) Button Switch Connection TracksNokia 2720 fold Volume UP(+) and Volume Down(-) Button Switch Connection Tracks



If you are looking for the connection line paths of the Nokia 2720 fold volume up and volume down control button switch, here we show the complete circuit connection of the said two volume control button switches.
This solution is a big help especially for a damaged or already lifted solder pads of the switches terminals.. or already been replaced a damaged button switch but still it doesn't work and fix the problem.

The solution below shows the connection of the Volume Up and Volume Down button switch of Nokia 2720 fold. Refer to it and use it as your tracing guide to troubleshoot a not working volume button keys.

 The two button switches share a common connection on its two upper terminals, which is connected directly to the keypad filter IC.
The lower terminals is Voume Up is also associated or connected to 0, 8, 5 and 2 keypad keys. While the Volume Down is connected to *, 7, 4 and 1 keypad keys. So, if also happens that those keypads keys doesn't work, it means that your problem may possibly lies on the filter IC.
You can check and trace this line paths using a multimeter. Then managed to apply a jumper wire if the said connection has been cut-off. Hope this helps in repairing volume control problem on Nokia 2720 fold cell phones.

Nokia 2720 fold LCD flex ribbon cable connector Nokia 2720 fold LCD flex ribbon cable connector Nokia 2720 fold LCD flex ribbon cable connector



Here's the basic Nokia 2720 fold solution for LCD screen display problems such as the following like white empty screen, blue screen, garbled or saturated screen, blurry or blur screen  displays and others as long you can hear that the phone is still working, like you can still hear the welcome tone, the keypad tones etc.

This may work if the LCD is not damaged, cracked or broken. For beginners  you may still need an LCD screen replacements for quick and easy technique by just confirming that the problem does not lies on the LCD screen. You may also check the device firmware first., if the firmware is okay then proceed to the given solution below.

Hints for troubleshooting the Nokia 2720 Display problems this may apply on the main LCD screen and the catalina LCD:
Check the flex ribbon cable assemblies for possible damaged.
Try to replace or install a new working LCD screen panel.

 If the LCD and flexible cable confirmed that nothing wrong with it, proceed to the PCB board hardware troubleshooting below. 

The solution below shows the connection line paths of the display data signals from the filter resistors through to the LCD flex pin connector. This is only the brief solution for we start our troubleshooting here.

nokia 2720 fold display jumper ways
First check the VIO and VFLASH supply voltages, you can read about 1.8V and 2.8V on that spots of the certain pins or through the capacitors. Then check all the resistors and trace its connection down to the LCD flex connector. This may useful especially when the device suffered wet or water damaged, replace and apply jumper if necessary. If this solution doesn't work, the problem may possibly then lies on the processor IC, it is because the display data signals is feed and comes from through it. A re-hot, re-work or replacement to the CPU IC will only fix the problem.

Okay, there you have it, the basic steps procedure in troubleshooting LCD screen display problem on Nokia 2720 fold. This once again created through by request of our colleagues on our Nokia solution request box.

Nokia 2720 fold Power ON-OFF Key Connection TracksNokia 2720 fold Power ON-OFF Key Connection Tracks



Here's the solution for Nokia 2720 fold Power On Off switch or END keypad problem,. This solution may only help fix the  2720 fold Nokia Mobile Phones, if the said device shows charging indications when the phone battery charger is plug-in but it doesn't turn the device ON when the power key is pressed.

To fix this problem, you may first check the keypad interface and keypad membrane for possible oxidation build up, clean or replace it if necessary, it might also cause the navigation and numeric keypad not to work.
Refer to this solution below if the basic procedures above doesn't fix the problem.



Nokia 2720 fold Power ON-OFF Key Connection  Tracks

Just trace the connection of the power key inner core to the capacitor and the ESD protection resistor then mend a jumper wire on it to reconnect if the said line paths is open or cut-off. The outer core is connected to ground lines, so check it as well. Replace those components also those components if necessary. If the connection paths and those components is okay, but still the 2720 fold don't turn ON, the possible problem may lies on the connection to the LITEPLUS IC. Reworking it and tracing the power key paths on the solder ball bumps C2 will only fix the problem.
