Troubleshooting
If you think there may be a problem with the device, first check the following points. If after checking these points the
problem persists, consult your dealer or local Roland Service.
Image not switching when fader is moved
If the same input is selected for both MAIN and INSERT while the EFFECTS MODE is set to OFF, moving the video fader
to switch the images will not change the image that is output.
In addition, switching the main input while the insert effects are in use automatically cancels the insert effects, so to start
using the insert effects again, first tilt the video fader completely to the MAIN side. Begin the insertion with the fader
tilted all the way to MAIN.
Image not switching when main input is switched
Are you looking at a display connected to MONITOR OUT? Select OUTPUT in the Monitor Select buttons. Alternatively,
you can connect the display to OUTPUT (the video output connector).
Images not switching as intended when the input is switched
You cannot use the same input simultaneously with both the composite and S-VIDEO connectors. The S-VIDEO takes
priority in this case.
No picture, even though source device is producing a signal
Is the Output Control button switched off (flashing)? If it is switched off, the screen will be black. Press the flashing
Output Control button to switch it to ON (lit), and the images are then output.
Transition effects not working
When the TIME setting knob is set near "0," no transition effect is attained when the main image is switched. You can
obtain the effect by using a longer time setting.
In addition, if the unit is not operating as you expect, first connect a display to the output of the device connected to the
LVS-400's input connector and confirm that the images are being output correctly.
