G. Troubleshooting
There is no image on the “head” display (the unit that initially receives source input)
1. Make sure that the VGA input has been selected on the display.
2. Double-check the local connection: Is the VGA Local on the LT card properly connected to
the VGA input on the display?
3. If there is still no image check the PC output by directly connecting the PC’s VGA cable to the
display’s VGA input. If there is an image on the screen this may indicate a defective card.
4. If after Step 3 there is still no image then swap the display with another display that has been
proven to function properly and re-install the LT card.
5. If after Step 4 there is still no image, swap the LT card with a card that has been proven to
function properly.
6. If there is still no image after following the preceding steps, the LT card is probably defective.
Please consult the product’s Warranty Card for service instructions.
