3.5.1 - Display Problems
If the display has some problems (such as no video, no horizontal or vertical
synchronization, raster non-linearity, etc.), remember that the video function of the
display and the touch screen installed on the display are separated systems.
Therefore, problems with the display should be treated as display problems, not
touch screen problems. Diagnostic procedures and any possible corrections for
display problems should be performed.
