Diagnosis of the line from the component video input to the HDMI video output
How to diagnose the line from the component video input to the HDMI video output is explained here.
1. Make the preparations described in "Preparations for diagnosis of the HDMI block and related systems" on the
previous page.
2. Remove the COMPOSITE V Assy and S VIDEO Assy.
3. Connect between the HDMI connector and the chassis. *1
4. Insert 75-ohm resistors separately between W4318 and W4316, between W4319 and W4316, and between W4320
and W4316 on the INTERFACE Assy to create impedance that matches the actual input impedance.*2
5. Connect a component video cable from the source equipment (DVD player, etc.) to W4318: Y IN, W4319: Pb IN, and
W4320:Pr IN, separately. *2
6. Connect a HDMI cable between the HDMI OUT connector and a TV monitor.
7. Referring to the instruction manual for this unit, assign COMPONENT INPUT 1 as DVD function. Set the INPUT
SELECTOR switch to DVD function.
*1: Be sure to connect between the HDMI connector and the chassis. Otherwise, operations will be unstable.
*2: Be sure to remove the resistors or jumpers after the diagnosis is finished.
