3-7 GUI and PLD failure detection procedure
When the results of check item (77) are "NO"
(When the menu display is not OK)
Check item(78). Check the format of the resistor video signal :
Send the following command from Termite.exe.
Send the command "i 0020 0070 0001".
Is the return value "22/21/20/1F/15/14/13/11/10/06/05/04/02" ?
Check the Video signal line. (GUI -> HDMI Tx)
Example
i 0020 0070 0001
