When the results of check item (3-8.2.) are "22"
(Detection of DDC is OK.)
Check item(3-8.5.). Checking register of the TMDS CLK detection status
register :
Send the following command from Termite.exe.
HDMI Rx/Tx
Send the command "i 0006 00FF 0001".
When the following value is returned, go to Yes.
HDMI IN4 "22" HDMI IN5 "11"
When the following value is returned, go to No.
HDMI IN4 "20" HDMI IN5 "10"
Check item(3-8.7.). Checking the audio signal output :
Check the audio signal waveform at the following test point.
Is the waveform like the sample?
129/131/132/133/134/135/136pin

Check item(3-8.6.). Checking the TMDS input waveform. :
Check the TMDS waveform at the following test point.
Is the waveform like the sample?
HDMI IN4
80/81/83/84/86/87/89/90pin
HDMI IN5
93/94/96/97/99/100/102/103pin

Checking the TMDS status register
Example
i 0006 00FF 0001
Check for a short circuit in the pattern of the
TMDS line of the HDMI Rx/Tx [IC721] from the
HDMI input terminal.
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.
Recheck from check item (3.2.).
If it does not work, replace the PCB.
The digital audio block is faulty.
Check the digital audio device.
Check "AUDIO" in troubleshooting.
If it does not work, replace the PCB.
