[1] Failure in Startup
[1-1] N o power
[2] Display (JOG FL/LED)
[2-1] The JOG FL does not light.
The JOG FL and the LEDs are controlled by the PA N EL CPU (IC 8 005).
[1-2] Indications on the LCD
Check the indications on the LCD.
N othing is displayed on the LCD. (Black screen)
Indications on the LCD are in white screen.
1 The SW power
does not function
properly. SR V B Assy Check V +12_EUP. If V +12_EUP (C N 7301 pin_1) is not output, the
SW power is defective. Replace it.
—————
2 The SW power
does not function
properly. P N LB Assy Check V +3R3_P N L. The regulator IC (IC 8 002) may be loosely connected
with its peripheral devices or a part may be defective.
Correct loose connection. If the symptom persists,
replace the defective part.
—————
4 V arious power
supply ICs do
not function
properly.
SR V B Assy,
MAI N Assy
Check each power-supply IC. The regulator IC and its peripheral devices for each
power supply may be loosely connected or a part
may be defective. Correct loose connection.
If the symptom persists, replace the defective part. —————
3 The EUP control
unit does not
function properly. SR V B Assy Check the EUP_CO N T signal. If the signal is L, check the output of the SW
power. If
V +12 (C N 7301 pin_2) is not output,
the SW power is defective. Replace it.
If the signal is H, see [10] EUP Mode.
—————
1 Power supply for
the backlight is
not input properly. TFTB Assy Check the connection on the V +12T line and
check the mounting status of the peripheral
parts of the backlight power circuit.
The V +12T line may be loosely connected or the
backlight power circuit may be defective.
Correct loose connection.
If the symptom persists, replace the defective part.
10.11, 10.12
TFTB ASSY
1 Power is not
supplied properly. JFLB Assy Check the power-supply voltages ( V +3R3,
V FDP2R7_F1, V FDP2R7_F2, and V +27)
of the FL.
Each power-supply may be loosely connected or
may be defective. Correct loose connection. If the
symptom persists, replace the defective part. —————
3 Defective JOG FL ————— If the symptom persists after the above
corrections, Replace the JOG FL. —————
2 Defective
control signal JFLB Assy Check that the FL control line is properly
connected in the JFLB ASSY.
• J_SCLK
• J_BK
• J_LAT
• J_DSO Check the connection and correct loose
connection.
As the JOG FL is controlled by the PA
N EL CPU,
if no signal is output, check the PA N EL CPU.
—————
Startup stops with the “Pioneer” logo displayed.
1 Communication
between the MAI
N
CPU and TFT CPU
could not be
established.
TFTB Assy,
MAI
N Assy
Check the serial communication cable
connection between the MAI
N CPU and
TFT CPU.
Diagnose the TFT CPU and its peripherals,
referring to [12-5] E-7023: GUI CPU ERROR. —————
1 The TFT CPU
does not function
properly. TFTB Assy Check the power supply and signals
around the TFT CPU.
•
V +3R3T_BF, V +1R2_BF
• RESET_TFT
• BUSCLK (Approx. 9
8 MHz)
Diagnose the TFT CPU and its peripherals,
