When the results of check item (3-9.2.) are "00 or 04"
(Detection of DDC is not OK.)
Check item(3-9.4.). Check the DDC Line HPD line :
Are waveforms of "DDCSCK" and "DDCSDA" observed at the test point near the HDMI input terminal
[JK701/JK711/JK721]?

Check the DDC line. (HDMI SW)
HDMI SW [IC701] is faulty.
Replace with a new device.
Check for a short circuit in the DDC line.
If there is no problem, the HDMI SW [IC701] is
faulty.
Replace with a new device.
Recheck from check item (3.2.).
If it does not work, replace the PCB.

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.
