| I think we need some notes regarding mobile hardware
initially we should note regarding the common faults such as mic, speaker, ringer etc.
As the procedure to measure positive prod of multimeter to ground and negative prod to a target point in a ohms range or buzzer range.
In a good and running set we would measure the value of mic point, speaker point, ringer point, lcd point etc, according to the model and make and note it on a fair.
In regarding to fault such as ringer from board in a set we mesure it and match it from our note and if singl or both the point differ from out note than it might be faulty from that track we should check it from first point to the last.
If we follow these rules than the faults from board would be much more easy. |
