Question about Nokia 8250 Cellular Phone
Keys; 2,5,8,and 0 are disable
For the model is, too often I see these problems arising from damage ic, most of which I see, the problem related to dropping out of the circuit or not connected. I usually use a microscope to see where the location of the circuit is broken. Without a microscope you can also search for the cause, you can use a multimeter, for keypad, I would prefer to name row and colum circuit, with a multimeter you try to check whether each gold pad keypad that is, whether among advanced, do a test by touching the pad outside the gold gold pads on each keypad problem. Because the outside, we call the vertical line, and it is connected between 2,5,8,0. horizontal lines between 1,2,3, and 3 if a problem does not it mean not to disturb the horizontal lines, clean the surface of the gold pad keypads using the eraser, and if the phone has entered the water, which causes the circuit is broken. If you make a Jumper keypad surface area, not too heavy or large, as this may disturb or cause it to function without you pressing the keypad.
