Troubleshooting - Roland V-440HD Owner's Manual

Troubleshooting

If the V-440HD does not function properly, first check the following
points before determining there is some malfunction. If after
checking these points the problem persists, consult the nearest
Roland Service Center or Roland dealer.
Video Output
Video not being output
Confirm that the connected video device is properly connected as
described in "Making the Connections" (p. 20). If the connections
are correct, check the following points.
• Appropriate format for video device not selected
Check to confirm whether or not the output selected is suited for the
video device connected to the HD/RGB output connectors.
• Output connectors and output format not properly selected
If the video device is connected to the HD OUT connectors, confirm
that 1080i or 720p is selected with the OUTPUT FORMAT button. If
the video device is connected to the RGB OUT connectors, confirm
that RGB is selected with the OUTPUT FORMAT button.
Video output is disrupted
• Final output not locked
Changing the V-440HD's output format settings may prevent
locking of the video with the device receiving the video. If this
occurs, try turning off the power to all devices, then turning on the
power to the transmitting device (e.g., video deck), the V-440HD,
and the receiving video device, in that order.
• Video output incompatible with receiving device
If the video output from the V-440HD is in a format that is not
compatible with the receiving device (such as a television monitor
or projector), the receiving device may be unable to output images
well. After confirming the formats compatible with the receiving
device, set the video output in the menu (p. 24).
• Reference signal (black burst signal) properly connected to
device requiring it
The V-440HD does not input or output reference signals (black burst
signals), thus video images may become disrupted when the
reference signals are connected to devices that require them. If this
occurs, use the following methods of avoiding disruption of the
video images.
• Input the signals output from the V-440HD's HD OUTPUT
connector 2 Y connector to the reference signal input
connector on the device requiring reference signals.
• Switch the device requiring the reference signal to a mode
that uses reference signals within the component signals.
Video input to the HD/RGB IN connectors is disrupted
• Instability of the video
Depending on the condition of the video signals input to the V-
440HD, the video image may become very unstable when the C-BUS
or D-BUS channel buttons are used to switch the video (when the
lock is off). If this occurs, go to "2. HD/RGB Input" (p. 59) in the
menu and set "1. Format Auto Detect" to "Manual," then select the
video to be input with "Input Format."
• Video being input to the BNC and D-Sub connectors on the
same channel
Inputting two video sources to the same channel creates interference
in the internal circuitry, resulting in disruption of the images. Input
video sources to different channels.
Color of input video is incorrect
As the V-440HD inputs and outputs HD, RGB, and SD signals as
analog signals, differences in individual devices can lead to color
variance, even with the same video sources. Correct these
differences with "2. HD/RGB Input" (p. 59) in the menu.
• Mistake in BNC connector used for inputting component video
When inputting component signals, connecting to the wrong BNC
connectors may result in video being displayed monochrome image.
Confirm that the connections to each BNC connector are correct.
Video images input to HD/RGB are disrupted
• Video being input with differing System Frame Rate settings (p. 49)
When the video format uses a different frame rate than the system
frame rate set for the V-440HD, the video image may at times move
in a disjointed fashion due to the frame rate conversion processing
required.
• Video being input with frame rate different than that for the
output format (p. 26)
When the video format uses a different frame rate than the frame
rate set for the V-440HD's output format, the video image may at
times move in a disjointed fashion due to the frame rate conversion
processing required.
Aspect ratio of video input using RGB
signals is off
• Settings not matching screen's aspect ratio
In some instances, the screen aspect ratio of the device to which the
finished video images are being input may not match the aspect
ratio of the RGB input video. Make the settings selected in the menu
(p. 24) to achieve the proper aspect ratio.
• RGB input's horizontal synchronization set to rate other than 60
Hz or 75 Hz
If the horizontal synchronization of the RGB video is not properly
matched to the 60 or 75 settings, the video image will be extended
vertically as a result.
• Does the signal conform to VESA standards?
• The RGB signal output of some devices may not properly
conform to VESA standards. When such signals are used, the
screen image may be extended vertically or horizontally as a
result.
If this occurs, you can adjust the aspect ratio of the RGB video
images by setting "6. Manual X Scale" and "7. Manual Y Scale"
under "2. HD/RGB Input" (p. 59) in the menu.
Screen shows visible vertical
discrepancies
The screen aspect ratio may be distorted if the format of the output
video does not match the settings of the device receiving HD output
or RGB output.
Not all of the video appearing in the screen
Some receiving devices may not display all of the video output from
the V-440HD. This may be due to differences in the size of the
region in which video is not displayed (the safe area) in some
receiving devices. To adjust the video size so that it does not reach
into the safe area, set "4. Zooming" under "1. HD/RGB Output" in
the menu.
