Troubleshooting
Cause
No signal input to HD SDI IN A
connector.
No signal input to HD SDI IN B
connector (in 4:4:4 mode).
The phase difference between the
HD SDI IN A and HD SDI IN B
signals is too large.
The format of the signal input to one
of the HD SDI IN A/B connectors is
different from the system signal
format.
Even though the setting of
REFERENCE is EXT, the signal
input to the REF IN connector is in
the wrong format, or there is no input
signal.
When the setting of REFERENCE is
EXT, input a reference signal in the
selected system signal format to the
REF IN connector.
The unit is playing back a section
where nothing is recorded.
The heads are dirty.
The input and reference signals are
unstable.
The SRW-1 is not powered on.
In 4:4:4 mode, the HD SDI A and HD
SDI B connections are switched.
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.
In 4:4:4 mode, the signal from the
VTR (HD SDI OUT B connector) is
not being input to the monitor.
Steps to take
Input a signal in the selected system signal format to the
HD SDI IN A connector.
In 4:4:4 mode, input signals in the correct format to both the
HD SDI IN A connector and the HD SDI IN B connector.
The phase difference may be too large, preventing proper
reception, if one of the cables connected to the HD SDI IN
A and HD SDI IN B connectors is much longer than the
other. Connect cables of the same length to both
connectors.
The picture is gray when an input signal format is different
from the system signal format. Input a signal in the correct
format.
When SD&HD is selected, and a proper HD signal is input,
a picture appears even if the SD signal is missing or in the
wrong format. When the SD is correct, a picture appears if
the HD signal is missing, but the picture is gray if the HD
signal is in the wrong format.
A gray picture appears when this unit is playing back a
section where nothing is recorded on the tape.
The heads can become dirty when playing back a
damaged section of a tape. Clean the heads.
The picture changes to gray when the input or reference
signals are unstable or interrupted.
The system does not operate properly when the SRW-1 is
not powered on, even if the SRPC-1 is powered on. Check
the power switches. Check with the operation panel.
Connect the proper signals to the HD SDI IN A and HD SDI
IN B connectors.
Set the input device to 4:4:4.
Input 4:2:2 signals.
Even if there is no signal from the HD SDI OUT B
connector, a picture appears on the monitor, which can
make it difficult to detect connection mistakes. Input a
signal from the HD SDI OUT B connector to the monitor.
