Suggestion(s)
Check that the video cable and power connectors are properly
connected as described in Chapter 2.
Make sure the pins of the connectors are not crooked or
broken.
Check that power switch of the touchmonitor has been pressed
and LED on the front of touchmonitor is lit.
Test the power supply by trying different cables, or a different
wall outlet or plug another appliance into the outlet.
Make certain the video cable is properly connected and that it
is not damaged. Check for bent pins on the cable connectors.
Ensure that your computer and video card are properly
configured (consult video card documentation) and the video
card is firmly seated in the card slot of the computer
motherboard.
Check the resolution and the frequency on the video port of
your computer.
Compare these values with the data in the Preset Timing Table.
The video signal from the computer does not comply with
VESA DPMS standard. Either the computer or the graphics
adapter is not using the VESA DPMS power management
function.
Check that the signal cable connector is properly connected
and that the connection pins are not bent or damaged.
If the connector is loose, tighten the connector screws. Check
that the computer is switched on.
