Hi everyone.
Can someone plz provide the instructions on how to detect faults etc according to the service manuals. For example i have one nokia 2600c with keypad problem. up and down keys are not working and all else are working fine. i checked all the things ( strip, jack etc) changed keypad ic ( Z2400) but problem is still same. i checked the service manual but i dont know how to find that where tracks are going from z2400.
Here is the attached picture from manual.
Can anyone plz provide any video etc to trace faults from service manuals.
Thanks
