Denon AVR-X3500H Service Manual

When the results of check item (3-14.3.) are "78 or 70"
(Detection of 5V is not OK.)
When the results of check item (3-14.4.) are "00 or 04"
(Detection of DDC is not OK.)
Check item(3-14.5.). Check the +5V voltage.
Does the HDMI Tx [U1001] test point indicate (5V)?
The test points are as follows.
U1001
106pin
Check item(3-14.6.). 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 (3.4.)
If it does not work, replace the PCB.
Recheck from check item (3.4.)
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.
YESYES
NO NO

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