Troubleshooting steps
The following hints should help to find the cause of the problem when the circuitry
seems to be faulty. This troubleshooting instruction is divided into sections.
1 Phone is totally dead
2 Power does not stay on or the phone is jammed
3 Flash programming does not work
4 Display is not working
5 Plug in SIM card is out of order (insert SIM card).
6 Audio fault
7 Charging fault
The first thing to do is carry out a through visual check of the module. Ensure in particular that:
a) there are no mechanical damages
b) soldered joints are OK.
Issue 1 10/02 ¤Nokia Corporation Page 33
Baseband Troubleshooting Instructions CCS Technical Documentation
General instructions
Most semiconductors are static discharge sensitive! ESD p rotection must be taken care
of during repair (ground straps and ESD soldering irons). HAGAR, PA, UEM, UPP, and Flash
are moisture sensitive and must be pre-baked prior to soldering, if they have been out of
their vacuum package longer t han the specified time.
• Connect test jig to computer with DAU-9S cable or to FPS-8 Flash Prommer with
AXS-4 serial cable.
• Make sure that you have PKD-1 dongle connected to computer’s parallel port.
• Connect DC power supply to module test jig with FLC-2 cable.
• Set the DC supply voltage to 3.9 V and set the module test jig (MJS-46) jumper
connector to ”bypass” position. VBAT must not exceed 5.15 V to avoid damaging
the power amplifier (PA), if PA is active.
•MJS-46’s current consumption is ~ 9 mA. Note that MJS-46 is not protected
against reverse voltage and there is a 2 A fuse which may blow if the phone
is short-circuited.
• When doing BB energy management (EM) calibrations use JBV-1 jig and DC supply voltage 12 – 15 V.
•JBV-1’s current consumption is ~ 40 mA with 3.9 V supply voltage and ~ 80
mA with 15 V supply voltage.
• Set the phone module to test jig and start Phoenix service software. Initialize
connection to phone (use FBUS driver when using DAU-9S and COMBOX driver
when using FPS-8).
Note! If a “No power” problem is found, please check the A-cover fit. For more information see section Assembly & Disassembly Instructions of NSM-9DX Service Manual, page 9.
PROGRAMMING FLASH
Fails in Programming Flash -Start:
• Most probably the phone has not started up properly for flashing.
• Try flashing with Phoenix (Figure 46).
• If flashing with Phoenix is not OK, check error code from the Phoenix
window (Figure 47) and check (Table 2: Flash Programming error
codes) for what is not working properly.

1 Check 26 MHz VCTCXO at TP20 (Test Point 20). Frequency deviation should be
<100 Hz). Check also TP3: Voltage should be 2.8VDC.
2 Check TX IQ signals at TP21. If not OK, change UEM.
3 Check 1880 MHz Ch661 at TP22. If OK, continue in step 8.
4 Check supply voltages for Hagar at TP4, TP5, TP6, TP8: 2.8 VDC; TP10 1.35 VDC
and TP1 4.8VDC. If voltages are not OK, change UEM.
5 . Check SDATA at TP51, SCLK TP53, SLE TP52.
6 Check TXC at TP23
7 Check frequency of VCO in TP40 (3760 MHz/ ch 661, TX mode). If not OK, check
TP7 2.8 VDC and TP41 ~2.8VDC. If TP41 is 4.8 VDC, the VCO doesn't probably
work. If all Hagar input signals are OK, probably HAGAR is broken -> Change
Hagar N600.
8 Check 1880 MHZ at TP25. If not OK, check Vbatt at TP9 3.9 VDC. Also check TP26.
If TP9 and TP26 are OK, PA is probably broken -> Change PA N700.
9 Check 1880 MHz at TP30. If not OK, check TP28. Also c heck TP 2 9 squarevawe 2.8

change V550. If that doesn't help change HAGAR N600.
5 Check RX signal level at TP36. If not OK, change Z551.
6 Check RX IQ signals at TP37 (also in burst-mode). If not OK, check HAGAR supply

MJS-46 Module Jig
All RF tunings should be performed in MJS-46 Jig. When using Test Jig MJS-46, the reference level attenuation is 0.1 dB + cable loss.
JVB-1 Docking Station, MJF-6 Adapter and coupler CPL-9
The reference level attenuation for Docking Station JBV-1 + MJF-6 adapter with antenna
coupler CPL-9 is approximately 4 dB +cable loss.There can be minor differences between
CPL-9 antenna couplers, but maximum distribution is +-0.3dBm. Attenuation can vary
between antenna couplers. There is differe n ces in attenuations between low and high
channel, but those can be ignored.
Coupler attenuation calibration
When Docking Station with MJF-6 and CPL-9 inside the shield box JSX-1 is used, then
calibration procedure is following:
• Measure one known phone in MJS-46 Module Jig in Ch 661, the output power
(P1) should be 29.5dBm +- 0.2dB. Remember the jig loss 0.1dB and cable loss.
• Assemble the measured phone in to mechanics
• Put the phone in to the JBV-1 Docking Station, without JXS-1 Shield Box
• Measure the output power (P2) in Ch 661
• The attenuation (A1) of the antenna coupler is: A1=(P1+0.5dBm)-P2
•(Note! Mechanics will increase output power 0.5dB)
Typical coupler (CPL-6) attenuation is 4.0dB. If measurements are done without JXS-1
Shield Box, the same value can be used in TX and RX.
If using shielded box JSX-1, additional loss is needed separately for LO, MID and HI
Channels. Typical loss values are: LO= 5.7dB, MID=2.3dB and HI=0.5dB
Functionality Testing Limits
When checking the phone’s functionality in the JBV-1 docking station with a coupler,
the TX power may vary to some degree. TX power levels 14 and 15 should be ignor ed, as
the coupler’s response is not reliable. The following table lists the TX output power tolerances, when CPL-6 is used for measuring:

JXS-1 Shield Box
Metal shielded box, mentioned to avoid disturbing RF signals, has a great effect to TX
output power, Bit error and Signal Strength reporting results, since the surface of
shielded box is reflecting RF-waves and therefore changing RF performance.
In following pictures the behavior of JVB-1 Docking Station with MJF-6 adapter is presented in JXS-1 Shield Box and without the box (coupler).
The measurements are done in the following conditions:
• Temperature +25
°C (77 °F)
• NOKIA 6590 Cellular Phone
• NOKIA JXS-1 Shield Box
• NOKIA JBV-1 Docking station with antenna coupler (1900 MHz)
• RF-Attenuation for MJF-6 and cable is 4.5dB
