Denon AVR-X3300W Service Manual

When the results of check item (53) are "78 or 70"
(Detection of 5V is not OK.)
When the results of check item (54) are "00 or 04"
(Detection of DDC is not OK.)
Check item(55). Check the +5V voltage.
Does the HDMI Tx (U1001) test point indicate (5V)?
The test points are as follows.
U1001
106 pin
5V
Check item(56). Check the DDC line :
Are the "DDCSCK" and "DDCSDA" waveforms for
the HDMI Tx (U1001) signal correct (as shown in the
gure)?
The test points are as follows.
U1001
DDCSCK
DDCSDA
Check the +5V voltage. (Front HDMI Buffer) Check the DDC Line. (Front HDMI Buffer)
HDMI Tx (U1001) is faulty.
Replace with a new device.
Recheck from check item (5).
If it does not work, replace the PCB.
Recheck from check item (5).
If it does not work, replace the PCB.
HDMI Tx (U1001) is faulty.
Replace with a new device.
Check for a short circuit in the 5 V line, the
Front HDMI FFC, and the 5 V Switch (U1002).
If there is no problem, the HDMI Tx (U1001) or
the 5 V Switch (U1002) is faulty.
Replace with a new device.
Check for a short circuit in the DDC line and
check the Front HDMI FFC.
If there is no problem, the Front HDMI
Buffer(U1022) is faulty.
Replace with a new device.

This diagram shows an example of the DDC commu-
nication waveform.
-The high level voltage is 5V.
-The frequency of the DDC CLK is 100 KHz or less.
Check at each test point.
