Problems with Video

No picture is input.

Is copyright-protected (HDCP) video being input?

Copyright-protected (HDCP) video signals can be input when they

meet all of the following conditions.

5

Input is via the HDMI IN 3 or 4 connector.

5

The HDCP setting is set to ON.

5

The 4:4:4 process is specified as the connection destination for

HDMI IN 3 or 4.

p. 20

Do the settings match the video format of the input?

Set the process format of the V-1200HD to match the video format of

the input to the 4:2:2 process.
For example, if the 4:2:2 process format on the V-1200HD is set to

1080/59.94i, the only video format that can be input to the 4:2:2

process is 1080/59.94i.
You can input video formats other than the set process format to

HDMI IN 3 and 4. For details, refer to “About HDMI IN 3 and 4” (p. 20).

p. 19

No picture is output.

Is copyright-protected (HDCP) video being output?

Check whether an HDCP-compatible monitor is being used.

Does the output-destination device (HDMI monitor, etc.)

support the output setting specified on the V-1200HD?

On the V-1200HD, video in the same format as the process format set

for the respective process is output.
For instance, if the process format for the 4:4:4 process is set to

1080/59.94p and video is output from the HDMI OUT 1 connector,

video output is possible if the output-destination device (HDMI

monitor, etc.) supports a 1080/59.94p signal.

p. 19

Are the patchbay settings correct?

Use an optional V-1200HDR unit or remote-control software to change

the patchbay settings. (*1)

Colors are incorrect.

Does the color space of the video being input or output

match the color space for the processing being done

by the unit?

Use an optional V-1200HDR unit or remote-control software to change

the settings for the color space. (*1)

Depending on the device, the color space might be interlinked with

the selection of DVI or HDMI or the selected format. In such cases,

changing the color space on the input or output device might bring

about improvement for the problem.

HDMI output shown on a display

has its periphery cut off.

Are the display settings compatible?

In the case of an HDMI signal, overscanning might be performed

automatically, depending on the display. Change the display’s

settings.

Other Problems

Remote control from a V-1200HDR

unit or V-1200HD RCS is not

possible.

Is the LINK indicator on the front panel dark?

Connect the V-1200HDR or V-1200HD RCS to the V-1200HD correctly.

p. 27

The body of the V-1200HD is

extremely hot.

Is an external power source whose voltage is outside

the range of DC 22 V to 26 V being used?

Stop using the external power source and use the included AC power

cord to supply from a power outlet.

p. 12

Has the cooling fan stopped?

Immediately stop use and contact a Roland Service Center.

Is the FAN indicator on the front panel flashing?

A USB flash drive cannot be read.

Was the USB flash drive formatted on the unit?

When you’re using a USB flash drive for the first time, be sure to

format it on the unit.

p. 30

Was a non-Roland USB flash drive used?

Operation of non-Roland USB flash drives cannot be assured.
Operation has been tested for commonly available USB flash drives,

but operation with all USB flash drives is not assured. Depending on

the manufacturer and type of the USB flash drive, correct operation

may not be possible.
