G660
- check voltage at C662, 2.8VDC
- check signal of 26MHz reference oscillator at C660:
With the voltage of 2.8VDC at C662 the oscillator
must be able to work on a frequency around 26MHz, else
you have to change G660.
N700
- in case you suppose a defect poweramplifier N700 to be responsible for the fault, first of all check the current consumption
of the phone. If current rises to more than 1 Ampere directly after connecting the phone to the servicebattery, remove
coil L703 and check current consumption again. If current is ok now you have to change poweramplifier N700 with help of
µBGA soldering machine and LGA rework kit LRK-1.
