3 Doesn’t start.
3.1 Find out if the phone will start by using the
On/Off-button.
Insert a fully charged battery and press the On/Off-button.
• If the phone doesn’t start, proceed to section 3.2
• If the phone starts, check the charging function by connecting a charger at the
system connector.
If the phone doesn’t charge, proceed to chapter 6 (“Charging”-fault).
If the phone starts (lights the background illumination, asks for SIM/PIN,
seeks the net…) and charges it’s probably not faulty or the problem is inter-
mittent.
Open the phone and make a visual examination of the circuit board.
The component side of the board is shown in fig. 3.1.
Fig. 3.1
Check for liquid damages anywhere at the board. Also check for burnt or damaged
pads at the system connector and faulty soldering at, for instance, D600, D610 and
D620 (fig. 3.2).
