5.8.8 Furore Nuclei
5.9 Test Instruction Front Display and Audio/
Video Board
These test instruction is designed specifically for SACD 2002
single disc models which has the following outputs:
• 6 Channel Audio output
• Coaxial / Optical digital output
• CVBS
• Component output YUV
• SVHS
• Double SCART output
• Front Display
5.9.1 General
• All the waveforms measurement carried out in these test
instruction will be base on the testpoint indicated in the
A/V Board and Front Display schematic diagram in the
Service manual.
• Impedance of the measuring-equipment should be > 1MΩ
• Most of the tests can be done using either the Diagnostic
software “ Player script” which can be found in the chapter
“Diagnostic Software description and troubleshooting” or
the Menu interface using the Service PC with a terminal
emulation program ( e.g. Window Hyperterminal ) where it
is possible to control the execution of the Diagnostic Nuclei
• Setup for the measurement will be done in set level with all
modules connected as shown in the Wiring Block diagram.
5.9.2 General Start-Up Measurement
Supply Check:
Before starting the measurement,ensure that all power supply
are connected to the A/V and Front Display board via
conn.1420 and 1108 respectively.
Clock Check
Ensure the present of the clock to the DAC and the slave µP.
Audio Mute Check
Measure the Audio mute voltage input at pin 22 of connector
1421
