Figure 2: FM Radio troubleshooting diagram

Set phone into local mode.

Start FM radio

Does the
radio start?

Check R363,
R365, R369,
R371 and retest
starting. Does it
start now?

Yes

Check N356
soldering, (pins
8,23,25,26,27,2
8,29,30,31)
Does it start?

Change
N356. Does
the radio
start now?

Baseband digital failure
(UPP)

OK, retest in FLALI

Connect RF test signal (note 1)

Set radio channel to 98.0 MHz
Set radio volume to maximum.

Yes

Measure signal
from testpoint
J371. Is it 1 kHz
0,3–0.5 Vp-p?

Set radio and RF
generator to 87.5
and 108.0 MHz.
Measure audio from
J371. Are both cases
OK?

Baseband analog failure
(UEM)

Yes

Measure signal
from N356 pin
12. Is it 1 kHz
0,3–0.6 Vp-p?

Check R360, R361,
R362, R381, C362,
C370, C371, C372,
C373.
Measure signal from
J371. Is it OK?

Check components
V356, V357, L356,
L357, C358, C359. Test
again with 87.5 and
108.0 MHz. Measure
audio from J371 Are
both cases OK?

Measure RF
signal over
Z357 (Note 2)
Is it 10.7 MHz
0,1–0,4 Vp-p?

Change Z357
and check
R359. Measure
signal from

Change N356.
Measure signal
from J371. Is it
OK?

Change radiomodule
LA5

OK retest in
FLALI

Check R358, R370,
V356, V357, C101,
C102, L101, C358,
C359, Z356, Z358
Measure signal from
J371. Is it OK?

Change V356, V357
(BOTH!).
Test again with 87.5
and 108.0 MHz.
Measure audio from
J371 Are both cases

Yes
