Troubleshooting

No output image

Check if there is any signal at the input.

Check if there is any signal at the output.

You can check these using an oscilloscope or a multimeter.

Ghosting on image

This is generally is not a faulty switch/scaler, but may be caused by poor quality cabling (to or from the switch/scaler), or incorrect setup on the display. Check cables and their connections, as well as the display setup.

Waves on image

If the output image has waves, especially if the waves move up or down, check that all devices and components (video players, computers, etc.) are grounded properly.

Poor color saturation

Double-check the input and output connections of all cables. Check for bent pins on VGA cables.

Static or waves become stronger when connecting using RCA connectors

Possibly due to incorrect grounding. Check grounding immediately. This could cause damage to the VSC device.

Remote control not working

Check that the batteries are inserted correctly. Check that the batteries are charged. Replace batteries as necessary.

RS-232 control not working

Check that the baud rate on the VSC device matches the baud rate set on the connected device.

When a computer is being used, check that the COM port set on the computer matches the COM port set in the OSD on the VSC device.

Make sure the serial port is in good working condition.

Try swapping the TX and RX at one one.

Power LED unlit

Make sure the power cord connection is good, and that the adapter (if used) is working. Make sure that there is power at the outlet.

Device does not respond when buttons are pressed on the front, when the remote control is used or when RS-232 communications are active.

The VSC device may need repair. Contact your dealer.
