Denon AVR-X2400H Service Manual

HDMI Tx [U1039] is faulty.
Replace with a new device.
Recheck from check item (3).
If it does not work, replace the PCB.
HDMI Tx [U1039] is faulty.
Replace with a new device.
Check for a short circuit in the TMDS line.
If there is no problem, the HDMI Tx
[U1039] is faulty.
Replace with a new device.
Check for a short circuit in the DDC line.
If there is no problem, the HDMI Tx
[U1039] is faulty.
Replace with a new device.
When the results of check item (58) are "30"
(Detection of HPD is OK / Detection of RXSENSE is OK )
Check item(59). 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 Termite.exe.
Are the rst eight bytes of the returned value "00FFFFFFFFFFFF00"?
Check item(60). Checking the TMDS :
Check the TMDS waveform at the following test
point.
