Abnormality in the
Sequence Processors
Communication error with the
left and right Sequence
Processors
SQ-IC
RTRY
CLK_SQ/TXD_SQ, etc.
IC3201, IC3301, IC3703
The communication between IC and the left and right Sequence
Processors is not established. (It is likely that IC3703 [sender] is in
failure, because communication is not established, neither that for the left
nor right Sequence Processor.)
Drive stop with the left and right
Sequence Processors
SQNO
Check if the video sync signal is input to IC3101.
CN3001, CN3002,
IC3001, IC3002, IC3101
If signal detection by the module microcomputer is properly performed,
the unit operates on an external sync. (Or both sides of the right part of
the screen, whose sync is not monitored, may be abnormal.)
Busy
BUSY
BUSY_SQ
IC3201, IC3301, IC3703
If BUSY_SQ remains high, a shutdown is generated.
Communication error with the
left Sequence Processor
RTRY/L
RXD_AL
IC3201, IC3409, IC3703
"RXD_AL" has not been transmitted to the module microcomputer
("RXD_AR" has been transmitted).
It is likely that IC3201 is not normally started.
Drive stop with the left Sequence
Processor
SQNO/L
Check if the video sync signal is input to IC3201.
CN3001, CN3002, IC3002,
IC3101, IC3201, IC3409
A shutdown is generated if IC3201 is not normally started
(communication error with IC3409 [flash memory]). (Or both sides of the
right part of the screen, whose sync is not monitored, may be abnormal.)
Incoherent version
(hardware, software)
VER-HS
Check the model number of the Digital Assy and the
destination of the sequence processors.
IC3101, IC3301
The written SQ_PROG is incoherent with data on the DIGITAL Assy.
Incoherent version (software, with the
left and right Sequence Processors)
VER-LR
Check the versions of the left and right sequence
programs.
–
Different sequence programs are written on the left and right Sequence
Processors.
Communication error with the
right Sequence Processor
RTRY/R
RXD_AR
IC3301, IC3410, IC3703
"RXD_AR" has not been transmitted to the module microcomputer
("RXD_AL" has been transmitted).
It is likely that IC3301 is not normally started.
A shutdown is generated if IC3301 is not normally started
(communication error with IC3410 [flash memory]). (Or both sides of the
right part of the screen, whose sync is not monitored, may be abnormal.)

Failure in IIC
communication with the
module microcomputer
DIGITAL Assy EEPROM
MD-IIC

IIC communication line of IC3701
IC3701, IC3703
Check the pull-up resistor of the IIC control line and the power to the
corresponding IC.

Abnormality in RST2
power decrease
–
RST2
–
Is the output voltage of the DC-DC converter low?
AXY1138
If RST2 does not become high after the unit is turned on, a shutdown will
be generated in several seconds.
The 12 V power is not output.
POWER SUPPLY Unit
Check if V + 12 V is started.
Blue 4
High temperature of the
panel
–
TMP_NG
TEMP1
Ambient temperature
–
If TEMP1 that is read by the module microcomputer is 75
°
C or higher, a
shutdown will be generated.
Abnormality in the panel temperature sensor
IC3901
Check the connection with the PANEL SENSOR Assy.
Blue 5
Short-circuiting of the
speakers
–
AUDIO
–
Speaker terminals
CN8402, CN8502
Check if any speaker cable is in contact with the chassis.
AUDIO_AMP
IC8001, IC5002
Check if the AMP output is short-circuited.
Periphery of the cable between A2 and M8
CN8002, CN4008
Check if cables are firmly connected.
