1 ————— ————— ————— If it is judged as N G, the USB-B controller (IC701)
does not work properly or communication between
the MAI
N CPU (IC10) and USB-B controller is not
established. Proceed as follows: See also “[4-2] N o
communication via the USB connector (Type B).”
—————
2 Power is not
supplied properly. MAI N Assy Check the power voltage of V +3R3_USB_
IO) line.
Check the connections of the power supply lines.
If soldering is improper, resolder it. —————
2 Power is not
supplied properly. MAI N Assy Check the power voltages of V +3R3_ETH
and V +3R3A_ETHR) lines.
Check the connections of the power supply lines.
If soldering is improper, resolder it. —————
3 The clock is not
properly input. MAI N Assy Check that the frequency at Pin 14
(USB_CLK) of USB-B controller (IC701)
is 4
8 MHz.
Check the connection of the logic IC (IC4).
If soldering is improper, resolder it. —————
3 The clock is not
properly input. MAI N Assy Check that the frequency at Pin 47 (X2) of
PHY CHIP (IC704) is 25 MHz. Check the connections between X1302 and
PHY CHIP. If soldering is improper, resolder it. —————
4 The RESET
signal is not
properly input. MAI N Assy Check that the signals of the USB_RST
and CPU_USB_RST lines are H. Check the connection of the logic IC (IC 8 ).
If soldering is improper, resolder it.
If the signal of the CPU_USB_RST line is L, the
port on the MAI
N CPU may be damaged.
If the signal of the USB_RST line is L, check the
connection of the logic IC (IC
8 ) and its periphery.
—————
4 The RESET
signal is not
properly input. MAI N Assy Check that the signals of the ETHER_RST
and CPU_ETHER_RST lines are H. Check the connection of the logic IC (IC 8 ).
If soldering is improper, resolder it.
If the signal of the CPU_ETHER_RST line is L,
the port on the MAI
N CPU may be damaged.
If the signal of the ETHER_RST line is L, check the
connection of the logic IC (IC
8 ) and its periphery.
—————
5 Loose connection
between the MAI
N
CPU and USB-B
controller
MAI N Assy Check the connection between the MAI N
CPU and USB-B controller.
Check the connections between MAI N CPU
(IC10) and USB-B controller (IC701).
If soldering is improper, resolder it.
—————
5 Loose connection
between the MAI
N
CPU and PHY
CHIP controller
MAI N Assy Check the connection between the MAI N
CPU and PHY CHIP controller.
Check the connections between MAI N CPU
(IC10) and PHY CHIP (IC704).
If soldering is improper, resolder it.

[12-3] E-7020: USB-B DE V ICE ERROR
The USB-B controller (IC701) does not work properly.
1 ————— ————— ————— If it is judged as N G, the PHY CHIP (IC704) does
not work properly or communication between the
MAI
N CPU (IC10) and PHY CHIP is not
established. Proceed as follows: See also
“[5-1]
N o LA N communication.”
—————
[12-4] E-7021: PHY CHIP ERROR
The PHY CHIP (IC704) does not work properly.
6 ————— ————— If the symptom persists after the above
corrections. Replace the USB-B controller (IC701). —————

2 Power is not
supplied properly. TFTB Assy Check the power voltages of V +3R3T_BF
and V +1R2BF) lines.
The TFT CPU requires two power supply systems.
Check the connections of the power supply lines.
If soldering is improper, resolder it. —————
1 ————— ————— ————— If it is judged as N G, the TFT CPU (IC4001),
FLASH (IC4004) or SD_RAM (IC4005) does not
work properly or communication between the
MAI
N CPU (IC10) and TFT CPU (IC4001) is not
established. Proceed as follows: See also
