(8-10) Y/C Output Check (AEP, UK model)
Color bar output by video encoder
Error 11: Serial transfer error
With AV-CONT: "H", E-V/Y: "L", E-V/RGB: "H", video signals
areoutput.
For the video signals, the color bars are output same as in (8-2).
(8-11) RGB Output Check (AEP, UK model)
Color bar output by video encoder
Error 11: Serial transfer error
With AV-CONT: "H", E-V/Y: "H", E-V/RGB: "L", video signals
areoutput.
For the video signals, the color bars are output same as in (8-2).
(8-12) AV CONT Wide Mode Check (AEP, UK model)
Color bar output by video encoder
Error 11: Serial transfer error
With AV-CONT: "H", VS: "H", video signals are output.
For the video signals, the color bars are output same as in (8-2).
(8-13) AV CONT Through Check (AEP, UK model)
Color bar output by video encoder
Error 11: Serial transfer error
Input picture is sent as it is from EURO AV2 (CNJ601) to the AV1
(CNJ602).
The color bars are output from the player, same as in (8-2).
As AV-CONT output signal is turned on/off repeatedly two times,
confirm that the picture output is switched between through and
color bar alternately.
(8-14) Component Output Check
Color bar output by NTSC Encoder in Video Encoder (IC252)
Error 11: Serial transfer error
With AV-CONT: "H", Component output "ON", video signals are
output.
The color bars are output from the player, same as in (8-2).
(9) Audio Concerned
(9-2) Sampling Frequency 44.1kHz
16.9344MHz oscillation
Error 37: PLL DAC (IC209) serial transfer interruption is not de-
tected
Sampling frequency 44.1kHz is set to the PLL DAC (IC209).
If no error is found, the message is displayed to prompt for key
entry.
Observe the output waveform of IC209 (CXD8696R) SCK02 pin.
(9-3) Sampling Frequency 48kHz
18.4320MHz oscillation
Error 37: PLL DAC (IC209) serial transfer interruption is not de-
tected
Sampling frequency 48kHz is set to the PLL DAC (IC209).
If no error is found, the message is displayed to prompt for key
entry.
Observe the output waveform of IC209 (CXD8696R) SCK02 pin.
(9-4) Sampling Frequency 96kHz
36.8640MHz oscillation
Error 37: PLL DAC (IC209) serial transfer interruption is not de-
tected
Sampling frequency 96kHz is set to the PLL DAC (IC209).
If no error is found, the message is displayed to prompt for key
entry.
Observe the output waveform of IC209 (CXD8696R) SCK02 pin.
(9-5) Audio Digital Output
ROM audio data → ARP (IC806) → AV Decoder (IC203) → Digi-
tal audio I/F output
Error 10: ARP (IC806) → AV Decoder (IC203) data transfer er-
ror
37: PLL DAC (IC209) serial transfer interruption is not de-
tected
AC-3-audio bit stream data stored in ROM (IC803) are transferred
to the AV Decoder (IC203) via ARP (IC806), and output to the
digital audio interface.
If no error is found, the message is displayed to prompt for key
entry.
Analog outputs are muted.
(9-6) Audio Digital Mute
ROM audio data → ARP (IC806) → AV Decoder (IC203) → Digi-
tal Audio I/F output
Error 10: ARP (IC806) → AV Decoder (IC203) data transfer er-
ror
37: PLL DAC (IC209) serial transfer interruption is not de-
tected
AC-3-audio bit stream data stored in ROM (IC803) are transferred
to the AV Decoder (IC203) via ARP (IC806), and output to the
Digital Audio Interface. In such a case, the mute signal is turned
on/off alternately while the data are output 4 times.
1st time : Mute off Audible
2nd time : Mute on Not audible
3rd time : Mute off Audible
4th time : Mute on Not audible
If no error is found, the message is displayed to prompt for key
entry.
