NO.
d. To check the power supply of main board B+
ACC should
be +12V; The voltage of stabilivolt of ACC power supply wire
ZD210 (6V8) should be 6V8
e. To check the voltage of the 19 pin (AVDD) of MCU (T5CL8)
should be +3V3; The output voltage of IC307 (LM2950) should
be +3V3
c. To check whether there is any contamination and bad
contact on the 22 Pin male/female connector on the panel and
main board
g. To check Panel LED +5V voltage , should be normal
a. To check whether the volume knob is turn to the minimum
position

a. To check whether it is connect well of the ISO connector
(4PIN power input ). Whether it is loose of the 15A fuse of the
ISO connector, or insert non in place
b. To check whether the reset button Sw201 is long term
functional then caused short circuit and no power

failure cause
failure phenomena
remark
CEM2100
e. To check the oscillation frequence of crystal XT001 of the
tuner, should be 32.768KHZ
d . To check the circuit of power amplifier IC501 (LV47004) and
VOL IC403 (PT7313E)
3
f. To check the oscillation frequence of crystal X201 , shuold be
8MHz, and for the crystal X202 should be 32.768KHZ
b. To check whether the unit is at MUTE mode, press SOURCE
button and check whether it is effective of the input sound
source
c. To check whether the connection of 8PIN audio output wire of
ISO connector is correct; wrong connection or short circuit to the
ground will caused the protection of the power amplifier( no
voltage output)
b. To check whether the strength of then input signal of the
tuner is too weak
Radio abnormal
f. To check the L output voltage of the 5 pin of tuner should be
1V5, the 6 pin R output voltage , should be 1V5
e. To check the normal voltage of 22 PIN(MUTE) of power
amplifier IC501(LV47004) , normally should be 4V
d. To check the voltage of the 10 pin(RES) of the tuner, should
be +3V6; the 11 pin(CLK) should be +3V1; the 12 pin(date)
should be +2V8
2
NO audio output
NO Power
c. To check the voltage of the 7 pin(VDD) of the tuner , should
be +3V3
f. To check the voltage of control PIN SDA
SCL
the 27
28pin
of audio processor IC403
PT7313E
, should be +3V3
a. To check the antenna of the tuner
