Items to check
The color space of the video being input or output does
not match the color space for the processing being
done by the unit.
HDCP is set to ON.
A monitor that supports HDCP is not being used.
The computer's driver for USB port is not up to date.
The connection is using an extension cable or USB hub.
At the USB Streaming screen, parameters are not set
correctly.
The device was not formatted on the VR-50HD.
A non-Roland USB flash drive was used.
Selecting a different connector than the connector
Specified by Input Assign was attempted.
HDCP is set to ON.
Because the buses needed for switching the video being
composited are insufficient, this problem occurs when
AUX Bus Source is set to a value from Video 1–Video 4
and PinP or PinP/KEY is used, and the mode is switched
while a WIPE operation is in progress.
When values related to the video being input and
output change, video corruption can occur when the
values are set.
The display settings are not compatible.
The HDMI output signal is not compatible.
Voltage of the external power source you are using is
not within DC 12 V–16 V.
The cooling fan malfunction.
Action
(When input or output HDMI, RGB/COMPONENT)
Use the menus to change the settings for the following parameters.
For details, refer to "Reference Manual" (PDF).
• Set Video Input Color Space.
• For Video Input, set Color Correction to its default value.
• For Video Output, set Color Correction to its default value.
Depending on the equipment, the color-space setting may change
with the selection of DVI or HDMI or the format selection. In such
cases, changing the color space on the input and output equipment
might correct the problem.
When HDCP is set to ON, no video other than HDMI is output. Also, no
output is made via the USB STREAMING connector.
Check whether a monitor that supports HDCP is being used.
Install the updated driver.
Connect the VR-50HD and the computer directly.
Touch <Reset> in the USB Streaming screen.
Lower the settings for Resolution and Frame Rate so that the Dropped
Frames value reaches "0. "
Format the device on the VR-50HD.
Operation of non-Roland USB flash drives cannot be assured.
Also, operation has been tested for commonly available USB flash
drives, but operation with all USB flash drives is not assured. Depend-
ing on the manufacturer and type of the USB flash drive, correct
operation may not be possible.
ANALOG/HDMI 1 is dependent on the Input Assign setting for channel
1, and ANALOG/HDMI 2 is dependent on the setting for channel 2.
Using Input Assign to select SDI makes it possible to choose Composite
or RGB.
When HDCP is set to ON, output can be made only to HDCP-compatible
HDMI equipment.
If you are using audio only, use a separate HDCP-compatible device
capable of de-embedding HDMI audio.
This is not a malfunction.
When you want smooth switching between memory sets before and
after call-up, set the values for the video output to PGM to the same
settings in both memory sets.
In the case of HDMI signals, automatic overscan occurs on some
displays. Change the display's settings.
Using the menus, go to Video Output and select DVI-D as the setting
for Signal Type.
For details, refer to "Reference Manual" (PDF).
Stop using the external power source and use the included AC
adaptor.
Immediately stop using the unit, and request servicing by your
retailer, the nearest Roland Service Center, or an authorized Roland
distributor, as listed on the "Information" sheet.
