2-4. Meaning of the indications
Format : The format of the video output signal is displayed:
NTSC : 525i, 4:2:2 component signals output from the SDI connector
PAL
: 625i, 4:2:2 component signals output from the SDI connector
• AVIB I/F: The status of the FFC cable to be connected to AVIB is displayed (only effective in Normal Operation
mode).
If there is no problem, 316 or 317 is displayed; 316 is displayed when no audio signal is being output from the
PRV-LX1 (during Stop mode, etc.), and 317 is displayed when the audio signal is being output.
Description of Indications Check / Measures
Place value of hundreds:
The conditions of the 27-MHz clock signal output from AVIB and
communication statuses are displayed.
3: No problem
2: Problem with communication statues
1: Problem with the 27-MHz clock signal
0: Problem with the 27-MHz clock signal and
communication statues
In a case when an indication other than 3 is displayed, the following
causes are possible:
• No or incorrect connection using the FFC cable
• Defective soldering at Pins 3 and 29 of CN8602
• Defective soldering at Pins 80, 178, and 182 of IC8611
Place value of tens:
The conditions of the video signal output from AVIB are displayed.
1: No problem
0: Problem with the video signal output
In a case when the indication is 0, the following causes are possible:
• No or incorrect connection using the FFC cable
• Defective soldering at Pins 11, 13, 15, 17, 19, 21, 23, and 25 of
CN8602
• Defective soldering at Pins 160-167 of IC8611
Place value of ones:
The conditions of the three-wire audio signal output from AVIB are
displayed.
2nd bit: Indication of the LR clock
1: With the LR clock
0: No LR clock
1st bit: Indication of the bit clock
1: With the bit clock
0: No bit clock
0 bit: Indication of conditions of the bit data
As the bit data do not change while no audio signal is
output, the data are not used for judging abnormality.
1: The bit data are changing.
0: The bit data are not changing.
7: No problem
6: No problem
5: Problem with the bit clock
4: Problem with the bit clock
3: Problem with the LR clock
2: Problem with the LR clock
1: Problem with the LR and bit clocks
0: Problem with the LR and bit clocks
In a case when an indication other than 7 or 6 is displayed, the
following causes are possible:
• No or incorrect connection using the FFC cable
• Defective soldering at Pins 6, 7 and 8 of CN8602
• Defective soldering at Pins 192, 193, and 194 of IC8611
