Denon AVR-X6300H Service Manual

When the results of check item (13) are "NO"
(Detection of 5V is not OK)
When the results of check item (14) are "00 or 04"
(Detection of DDC is not OK.)
Check item(15). Check the +5V voltage.
Does the test point near HDMI input terminal (N2400/N2401/N2402) indicate 5V?

Check the +5V voltage. (HDMI IN5 - 7) Check the DDC line. (HDMI IN5 - 7)
HDMI Switcher1 (U2401) is faulty.
Replace with a new device.
Recheck from check item (3).
If it does not work, replace the PCB.
HDMI Switcher1 (U2401) is faulty.
Replace with a new device.
Check the 5V line for soldering faults and the 5V
Switch IC (U2400).
If there is no problem, the HDMI Switcher1
(U2401) or the 5 V Switch IC (U2400) is faulty
Replace with a new device.
Check for a short circuit in the DDC line.
If there is no problem, the HDMI Switcher1
(U2401) is faulty.
Replace with a new device.
Recheck from check item (3).
If it does not work, replace the PCB.
