Denon AVR-X2400H Service Manual

5. Network / Bluetooth / USB
Check the setting
Are the network settings of this unit correct?
Are peripheral devices such as the router and hub
connected to this unit correctly?
Are the router settings correct?
Set the IP address, etc. correctly.
When the static IP address is used, check that no
other devices have the same IP address and that
the subnet mask settings are correct.
Connect the peripheral devices correctly.
Check the instruction manual of the router and
congure the settings correctly.
Check that there are no connection restrictions by
MAC addresses, etc.
5.1. Cannot connect to the network
Is the LAN cable correctly inserted?
Insert the LAN cable correctly and then turn on
the power again.
Check the connection environment
Checking the unit
Can the output voltage (5V) to
[Q1074 : FET-SW] be conrmed?
Can the voltage (5V) be conrmed between
[N1033 : 2-5pin]?
Is NET5V POWER [U1018 : 48pin
uCOM ] "Hi" ?
The circuit of NET5V POWER
between [U1018-Q1074 : FET-
SW] are faulty.
The circuit around [Q1074 : FET-
SW] is faulty.
The circuit between the AC inlet and [N1033] is
faulty.
Check the SMPS PCB.
Can the output voltage (3.3V)
to [U1067 : DC-DC Conv.] be
conrmed?
Can the output voltage (3.3 V)
to [Q1071 : FET-SW] be con-
rmed?
Is D5V_POWER [U1018 :136 pin
uCOM] "Hi" ?
Is NET3.3V POWER [U1018 : 135
pin uCOM] "Hi" ?
The circuit of D5V_POWER
between [U1018-U1067] are
faulty.
The circuit of NET3.3V POWER
between [U1018-Q1071] are
faulty.
The circuit around [U1067 : DC-
DC.Conv.] is faulty.
