When the results of check item (3-15.1.) are "YES"
(When the menu display is OK)
HDMI
Turn Video Conversion "ON" on the setup menu.
(SETUP MENU-> Video-> Output Settings-> Video Conversion = On)
In order to check, connect the player to the HDMI terminal and configure the player as AVR source.
Next, turn on the power for the player and TV and start playback on the player.
Check the Video signal line. (HDMI Tx -> PLD)
IN1 HDMI OUT
Check item(3-15.5.). Check the PLD video signal line from the HDMI
Tx :
Check the video signal waveform at the following test point.
Is the waveform like the sample?
U1001
R2204
YES
Check the peripheral pattern between the HDMI Tx [U1001] and PLD [U1011].
If there is no problem, the HDMI Tx [U1001] is faulty.
Replace with a new device.
Recheck from check item (3.5.)
If it does not work, replace the PCB.
Check the Video signal line. (PLD -> GUI)
Check item(3-12.6.). Check the GUI video signal line from the PLD :
Check the video signal waveform at the following test point.
Is the waveform like the sample?
R2217
U1026
YES
GUI [U1026] is faulty.
Replace with a new device.
Recheck from check item (3.5.)
If it does not work, replace the PCB.
