Denon AVR-X3300W 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 of RXSENSE close to the HDMI input terminal (N1005/N1006/N100) indicate the 5V?
IN7
5V
IN6 IN5
5V 5V
Check item(16). Check the DDC line :
Are waveforms of "DDCSCK" and "DDCSDA" observed at the test point near the HDMI input
terminal(N1005/N1006/N1007)?
DDCSCK
DDCSDA
IN7 IN6 IN5
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).
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 5 V line and the 5
V 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.
Replace with a new device.
Recheck from check item (3).
If it does not work, replace the PCB.
