Network / Bluetooth / Usb; Cannot Connect To The Network - Denon AVR-S950H Series Service Manual

5. Network / Bluetooth / USB

5.1. Cannot connect to the network

Check the connection environment
Is the LAN cable correctly inserted?
YES
Check the setting
Are the network settings of this unit correct?
YES
Are peripheral devices such as the router and hub
connected to this unit correctly?
YES
Are the router settings correct?
YES
Checking the unit
Can the voltage (5V) be confirmed between
[N1033 : 2-5pin]?
YES
NO
Insert the LAN cable correctly and then turn on
the power again.
NO
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.
NO
Connect the peripheral devices correctly.
NO
Check the instruction manual of the router and
configure the settings correctly.
Check that there are no connection restrictions by
MAC addresses, etc.
NO
The circuit between the AC inlet and [N1033] is
faulty.
Check the SMPS PCB.
NO
Can the output voltage (5V) to Is NET5V POWER [U1018 : 48pin
[U1080 : FET-SW] be confirmed? uCOM ] "Hi" ?
YES
Can the output voltage (3.3V) to [U1067 : DC-DC
Conv.] be confirmed?
YES
NO
Can the output voltage (3.3 V)
Is NET3.3V POWER [U1018 : 135
to [U1079 : FET-SW] be con-
pin uCOM] "Hi" ?
firmed?
YES
82
NO
The circuit of NET5V POWER
between [U1018-U1080 : FET-
SW] are faulty.
YES
The circuit around [U1080 : FET-
SW] is faulty.
NO
The circuit around [U1067 : DC-DC.Conv.] is faulty.
NO
The circuit of NET3.3V POWER
between [U1018-U1079] are
faulty.
YES
The circuit around [U1079 : FET-
SW] is faulty.
