Check USB cable is fitted correctly (at both ends). Check USB cable length is not over 5m. Try a different USB lead. Ensure there is power to the screen and a picture is showing. Try a different PC. Check the IR frame is clean. Check nothing is blocking the IR frame. Ensure screen is not in direct sunlight. Ensure driver is installed correctly.

Ensure the picture fills the screen, with no black borders or parts of the picture missing. Recalibrate the screen using the calibration software.

If the base has power and is operational, there may be a problem with the power lead which connects from the top of the base unit to the screen. Please check this cable is not damaged and is plugged in properly at both ends. (Turn off the mains power supply whilst checking linking cable to avoid possible shock if damaged.)
