Here is the solution for the Nokia 2720 fold Power On Off Switch or END key problem. This solution can only help determine the 2720 Fold Nokia Mobile Phones, said if the device gives instructions when
charging the phone battery charger is a plug-in, but it does not turn the device on when the button is pressed.
To solve this problem, you first keyboard interface and keyboard membrane for possible oxidation build, clean or replace if necessary, it can also lead to the navigation and numeric keypad does not work.
Below refer to this solution as the basic procedures above did not fix the problem.
Just trace the connection of the inner core of the test capacitor and the ESD protection resistance than restoring a jumper wire to connect the line and said path is open or cut-off. The outer core is connected to ground lines, so check it. Replace these parts also those parts as needed. If the connection paths and these components is okay but still not off the 2720 Fold, the potential problem lies in the connection with the LITE PLUS IC. Reformulated and trace the paths of key onto the solder ball bumps C2 will only solve the problem.
