Customer Care Europe & Africa Version 5.0 Approved

Technical Services Training Group Date: 05.09.2001

PHONE DOES NOT SWITCH ON

At first always check mechanical appearance of battery connectors X101/X102 if bent or dirty etc. -defect connectors could cause additional faults like "not charging" or the phone switches off intermittently.

Does not switch on with battery (nor with service battery)

Check if phone works properly in service jig. Check if BTEMP AD value is in range of 300.

Check battery connectors X101 / X102 for broken solderings or bent spring contacts (see pictures below). Check if phone works also after connecting LCD module in jig (short circuit in VBB line from LCD possible).

X504 related fault

Check if connector X504 has its correct position - especially after rework in its area.

If it is misplaced or bent, it could cause possible short circuits to D - Cover with throughholes.

POWER switch S416 faulty

Check mechanical condition of S416.

Check if PWRON at R413 drops to 0V during pressing power switch. Change powerswitch S416 or continue with CCONT chapter on page#17.

L102 broken/poor soldered

Check soldering of L102. Check resistance of L102 = 0Q. Resolder coil or change if necessary.

See the different versions of coil in HW changes chapter on page#9.

VB line faulty

Check battery voltage VB 2.7VDC at L102.

Check VB 2.8VDC at R132.

Check connection (0Q) between R132/L102.

See HW changes chapter on page#9 for additional PCB protection.

Customer Care Europe & Africa Version 5.0 Approved

Technical Services Training Group Date: 05.09.2001

DC/DC Converter V105 faulty

Check the difference between V101 cathode 3.2VDC / anode 2.6VDC. Check at V105 - pin 4, 5, 12, and 13: switching frequency 600kHz. Check 1.2VDC at V105, pin 15.

Check at V105, pin3: 0V. If not, check the respective voltage dividers R131, R132, R134, R143, R144. If all ok - change V105.

FLASH D301 / SRAM D302 related faults

Check if the current consumption is approximately 20mA.

Try to flash the phone - if this does not work go to chapter "FLASH update not possible" on page#30.

Check also near the service contacts on the PCB - If any component is missing (like on picture below) - flashing will not work!

Torn off components are the result of sliding the phone on the service battery - the contacts can be damaged, too. NOTE: Always handle the phone in combination with the service battery with care to prevent those failures!

G701 faulty

Check VCC 2.8VDC at C750 (Phone must be set in local mode).

Check control voltage (AFC) 0.1 - 2.3V at C715.

Check 13MHz reference frequency ±50 Hz (900mVpp) at R743.

NOTE:

If you have to change the oscillator, pay attention to use the correct one - also see HW changes chapter on page#8
