94 Troubleshooting
Cause
No input signal is being supplied to
HD SDI IN connector A.
No input signal is being supplied to
HD SDI IN connector B(when
using 4:4:4 format).
The phase difference between HD
SDI IN A and HD SDI IN B is too
large.
The format of the input signal to the
HD SDI IN connector A or B is
different from the system format.
The input signal is unstable.
In 4:4:4 mode, the HD SDI A and
HD SDI B connections are
reversed.
In 4:4:4 mode, two 4:2:2 pictures
are being input to the HD SDI IN A
and HD SDI IN B connectors.
In 4:2:2 mode, a 4:4:4 picture is
input.
The input signal is unstable.
The monitor does not support the
format.
The input signal is not matched to
the system frequency.
The frequency exceeds the monitor
scanning frequency.
Wrong interlace and PsF selection. Set the input signal format so as to match the
Monitor is not operating properly.
In the SMPTE 372M 4:2:2 60p
standard, the active lines of digital
field 2 are different between Link A
and Link B (Link A: line 584 to
1123, Link B: line 583 to 1122).
This can be done with a menu
setting.
Countermeasures
Supply the input signal for the selected system
format to HD SDI IN connector A.
To enable use of the 4:4:4 format, input a
signal with the correct format to HD SDI IN
connectors A and B.
If the length of the cable connected to HD SDI
IN A and HD SDI IN B differs significantly,
the signal phase shift may be too large,
preventing normal signal reception. Ensure
that the two cables are of similar length.
The picture is gray when an input signal
format is different from the system signal
format. Input a signal in the correct format.
The picture changes to gray when the input
signal is unstable or interrupted.
Connect the proper signals to the HD SDI IN
A and HD SDI IN B connectors.
Set the input device to the 4:4:4 format.
Input a 4:2:2 format signal.
Supply a correct input signal.
Some older monitors support only the 59.94/
60 frequencies. The 720-50p format is only
supported by some of the newest monitors.
Use a monitor with specifications supporting
the format.
Input a signal with 1.000/1.000 and 1.000/
1.001 that match the system.
If the monitor is a BVM-F24, 25PsF and
29.97PsF cannot be displayed with ×3
scanning, resulting in picture breakup. Use ×2
or ×1 scanning. For 59.94i and 50i, use ASD
scanning.
system setting.
Check the monitor settings. Try turning it off
and on again.
Ensure that the source signal conforms to the
SMPTE 372M 4:2:2 60p standard.
