Diagnosis of the line from the S video input to the HDMI video output
How to diagnose the line from the S video input to the HDMI video output is explained here.
1. To forcibly input the signal to the video converter circuit, short-circuit between the pads to R2231 (C input) and
R2232 (Y input) on the S VIDEO Assy. *1
2. If the video output from the S VIDEO Assy is to be monitored, short-circuit between R2294 (C output) and
R2295 (Y output) on the S VIDEO Assy.
3. Make the preparations described in "Preparations for diagnosis of the HDMI block and related systems."
4. Connect between the HDMI connector and the chassis, and between the composite connector and the chassis,
separately.*2
5. Connect a S-video cable from the source equipment (DVD player, etc.) to the S-VIDEO INPUT 1 connector.
6. Connect between the HDMI OUT connector and a TV monitor. (When Step 2 above is performed, the signal from the
S-VIDEO OUT connector can be monitored. When Step 2 in "Diagnosis of the line from the composite video input to
the HDMI video output" is performed, the signal from the COMPOSITE OUT connector can also be monitored.)
7. Assign S-VIDEO INPUT 1 as DVD function. Set the INPUT SELECTOR switch to DVD function.
*1: Remove the solder used for short-circuiting after the diagnosis is finished.
*2: Be sure to connect between the HDMI connector fitting and the chassis, and between the composite connector fitting
and the chassis, separately. Otherwise, operations will be unstable.
