TouchWare for Windows NT User's Guide104
Any time you disassemble a monitor to install a touchscreen or to
repair another monitor component, use these commands to test that
the video output is still functioning properly. If the video does not
function properly, there is a problem with the monitor hardware.
Possible explanations are as follows:
You forgot to connect all wires or failed to connect the wires
properly.
You bent one or more pins on the CRT.
You did not install the video board correctly.
The video board is bad.
Your initial test verifies that the video functioned properly before you
did any work on the monitor. You can also compare your results with
the results you get after you install the touchscreen.
Note:
The Color Bars and Color Purity options test the video output
of the monitor. These options do not test the touchscreen.
Color Bars
When you select the Color Bars option, Microcal displays 16 bars that
span the color spectrum from black to white.
When examining the colors, check the following items:
Look at each color. Check that each color matches the description
below the bar.
Look at the edges of each color bar. Check that a color does not
bleed at the edge or spread into other colors.
Use the left and right arrow keys to change the color of the border
around the edge of the screen.
