Troubleshooting
If you suspect a malfunction, please check the following points. If this does not resolve the problem, contact a nearby EDIROL/Roland
Service Center.
Problems with the image output
Problem
Cause and Action
The power does not turn on when
you press the [POWER] switch.
●
Could you be using an AC adaptor other than the included one?
➔
Use the included AC adaptor.
Problems with the image output
Problem
Cause and Action
No image is output
●
Could the [OUTPUT FADE] fader be lowered?
➔
With the factory settings, lowering the [OUTPUT FADE] fader will fade the image. Raise the
[OUTPUT FADE] fader.
●
Have you used the INPUT SELECT buttons to select an appropriate input channel?
➔
Select a channel into which an image is being input.
●
Could the [FADE] button be blinking?
➔
If the [FADE] button is blinking, you can use the [CONTROL] fader to fade the image of bus A or
bus B. Raise the [CONTROL] fader.
●
Is an image being output from the connected video device or PC?
●
Have you selected the correct input on the projector or television monitor to which the V-8’s
signal is being output?
●
Is the correct video format (NTSC or PAL) specified?
➔
Specify NTSC or PAL as appropriate for the format of the input signal.
☞
Operating the video fader does not
change the image
●
Could the same image be selected for bus A and bus B?
➔
If the same image is selected for bus A and bus B, operating the video fader will not change the
output image. Select different images for bus A and bus B.
Image is distorted
●
It may be that the level of the synchronization signal being output by your video equipment
is below the allowable level.
➔
Try adjusting the “Utility” menu item “Video Sync Threshold.” This may allow synchronization to
be achieved so that the image will display correctly.
●
Is the correct video format (NTSC or PAL) specified?
➔
Specify NTSC or PAL as appropriate for the format of the input signal.
☞
●
Could you have used the [PC INPUT SELECT] switch to change PC inputs?
➔
When you switch PC inputs, it will take some time for the input to stabilize. We recommend that
you use the monitor to verify the image.
●
Could you be displaying moving images from a PC input?
➔
Displaying moving images from a PC input may cause skewed or flickering images. This is a
phenomenon called “tearing,” and is not a malfunction.
☞
●
Could you be using the INPUT SELECT buttons to switch the image?
➔
If the video fader is not set all the way to the bus A or bus B position, using the INPUT SELECT
buttons to switch channels will cause the image to be distorted, but this is not a malfunction.
Before using the INPUT SELECT buttons to switch between images, perform the following oper-
ations or settings. This will allow smooth transitions between images without switching noise.
•
Set the video fader all the way to the bus A or bus B position (the bus that is outputting the
image).
•
Raise the value of the “Utility” menu item “Input Select Delay Time.”
