5. Play and 16/9 Detection
Check 0/6/12 signal on pin 8 of the SCART connector
1130 and change the input with the following commands:

Since in SD4 based single SCART players, pin 8 output is
determined by SCART0 and standby control signal. Since
standby control must be LOW when diagnostic is running,
we can only set pin 8 to 6V or 12 V.
6. Kill Circuit
To check the functionality of the Kill circuitry,the audio
outputs has to be present by the following command:

7. Digital Silence
Digital silence is a signal from the audio DAC, KILL_LR,
when there is no input to the audio DAC, or when the
player is in STOP/PAUSE mode, or during disc changing
track.
To check the KILL_LR signal, use the following command
and check the voltage level at pin 16 of 7200:

8. Front Display
To check the segment display of the FTD, the following
command can be used. And for full detail description of the
test, refer to the chapter of “Diagnostic Software Player

9. IR Receiver
Check at pin 22 of 7101 and observe if this line switches
from LOW (<0.3V) to HIGH (>4.5V) when pressing a key
on a remote control.
