|If the power LED on the unit is off or red and there is nothing displayed on the LCD, then insure that the AC power cord is connected properly and the power switch is on at the AC outlet. Press the standby button on the unit to turn it on.|
If the power on the unit is green and the LCD is displaying the correct text then check that the monitor output from the computer is connected at both the computer and the scaler unit.
Check that the output connector you are using from the scaler is also connected to the display equipment. Check that the target video equipment is set to the correct line input if appropriate.
Check that the device connected to the output is on and can support the resolution set in the Output image menu, ensuring that the Output image type (eg. RGBHV) is also set correctly.
If none of this works, try a firmware update.
