LOCATION UPDATE
No Service EGSM & DCS TX good in testmode (TX I/Q and RF) + RSSI good in test
mode (RX I/Q and level) + IC 600 replaced
xg014 IC300
No Service EGSM & DCS TCXO frequency no good and impossible to adjust with
TCXO adj val in testmode
xg015 X600
No Service EGSM & DCS TX no good in testmode, consumption > 300 mA, IC701

POWER ON PROBLEM
Normal consumption in TestMode :
45mA to 49mA
Power on no good Displayed Test Mode when battery connected on mobile
PS=4,5 V instead 0 V and HFDETL=0 V xg007 R148
No power on Consumption at 15 mA X600
No power on Consumption at 30 mA download or change
IC201
No power on check PS TCXO-check L603-PSTCXO=2.8 V xg012 L603 (resoldering
only)
No power on Power on OK with EXPS and TESTPS & visual check :
dirty battery contacts.No power on with batt. xg016 cleaning the battery
contacts
No power on No 13 MHz and Fadj voltage no good, consumption at
60mA xg018 IC300
Short autonomy 800 mA < Ich <1.5 A IC701
No power on and no "check battery" displayed when ACDC connected
on mobile without battery xg020 download SW
No power on 2.8 VD no good on C114 and 3.6VBat is very low xg026 TR100
No power on Displayed Contact Provider xg011 download SW
No power on Displayed Contact Provider xg011 IC201, IC203
Turn on in Testmode TESTPS voltage is 1 volt instead of 0 (R148 is broken:
value is 68kohms instead of 1 kohms) xg025 R148, R147, IC203,
IC201
