age at N705 pin 2 (~3.1V, fig. 7.4).
Fig. 7.3 shows the component side of the circuit board.
• If the input voltage is too low or missing, check the VDIG feed voltage (~3.2V) at C600 (fig. 7.4).
• If VDIG is too low, measure the resistance from it to ground (>500 ohms).
• If it's correct, replace N702 (class A, fig. 7.4).
• If it's too low there's a short circuit in one of the circuits fed by this regulator. Send the phone to the
