• If the soldering is correct, replace H650.
* If that doesn´t fix it, measure the resistance between H650:3 (fig. 9.7) and
D600:94 (fig 9.8) (~0 Ohm)
* If the resistance is ~0 Ohm, replace D600
* If the resistance is larger, is there a foil damage.
If the fault still remains, send the phone to the next repair level.
9.6 Red top indicator doesn´t work.
Open the phone and check for liquid damages.
If the green top indicator (should flash green when the phone has got serv) doesn´t
work either, make sure the soldering is correct and measure the resistance of R646
(~470 Ohm, Fig. 9.7).
Make sure the double LED H650 (class A, Fig. 9.7) or D600:93 (Fig. 9.9) are cor-
rectly soldered.

• If the soldering is correct, replace H650.
