Denon AVR-X3500H Service Manual

When the results of check item (3-11.1.) are "NO"
(Detection of 5V is not OK)
When the results of check item (3-11.2.) are "00 or 04"
(Detection of DDC is not OK.)
Check item(3-11.3.). Check the +5V voltage.
Does the test point near HDMI input terminal [N1005/N1006/N1007] indicate 5V?

Check the +5V voltage. (HDMI IN5 - 7) Check the DDC line. (HDMI IN5 - 7)
HDMI Switcher1 [U1003] is faulty.
Replace with a new device.
Recheck from check item (3.2.)
If it does not work, replace the PCB.
HDMI Switcher1 [U1003] is faulty.
Replace with a new device.
Check for a short circuit in the 5V line and the 5V
Switch IC [U1002].
If there is no problem, the HDMI Switcher1
[U1003] or the 5 V Switch IC [U1002] is faulty.
Replace with a new device.
Check for a short circuit in the DDC line.
If there is no problem, the HDMI Switcher1
[U1003] is faulty.
