Replace with a new device.
Recheck from check item (3.3.).
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 (3-13.4.) are "30"
(Detection of HPD is OK / Detection of RXSENSE is OK )
Check item(3-13.5.). 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(3-13.6.). Checking the TMDS :
Check the TMDS waveform at the following test
point.

Check item(3-13.7.). Check the communication :
Are waveforms of "DDCCLK and DDCSDA" ob-
served at the test point near the HDMI output
terminal [N1031]?

Example
The rst eight bytes are nor-
mally "00FFFFFFFFFFFF00".
*If the AVR and the TV are not
connected via HDMI, the cor-
rect register value cannot be
veried.

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