Denon AVR-X1600H Service Manual

Example
The rst eight bytes are normally
"00FFFFFFFFFFFF00".
*If the AVR and the TV are not con-
nected via HDMI, the correct register
value cannot be veried.
m_1
When the results of check item (3-11.3.) are "03"
(Detection of HPD is OK / Detection of RXSENSE is OK )
Check item(3-11.4.). Check the Monitor EDID :
① Unplug the AC cord. Plug the AC cord into a power outlet.
② Send the transmission command "m_1" from Termit.exe.
Are the rst eight bytes of the returned value "00FFFFFFFFFFFF00"?
Check item(3-11.5.). Checking the TMDS :
Check the TMDS waveform at the following test
point.

D2+ D2- D1+ D1- D0+ D0- CK+ CK-
Check item(3-11.6.). Check communication with
the monitor :
Are waveforms of "DDCSCK" and "DDCSDA"
observed at the test point near the HDMI output
terminal [JK751]?

Checking the EDID register. (Monitor)
HDMI Rx/Tx [IC721] is faulty.
Replace with a new device.
Recheck from check item (3.3.).
If it does not work, replace the PCB.
HDMI Rx/Tx [IC721] is faulty.
Replace with a new device.
Check for a short circuit in the TMDS line.
If there is no problem, the HDMI Rx/Tx
(IC721) is faulty.
Replace with a new device.
HDMI Rx/Tx [IC721] is faulty.
Replace with a new device.
