Troubleshooting Diagnosing A Suspected Hardware Problem/Using the AppleVision
Diagnosing A Suspected Hardware Problem
After ruling out other possible cures (that is, you have already
checked cable connections, power, AppleVision software, and other
possible front-of-screen cures), use the following procedure to
help determine and resolve hardware problems. (See the
flowchart at the end of this chapter for a simplified depiction of
this process.)
1 If the problem is a completely black screen, connect another
known-good display (not an AppleVision or ColorSync
display) as follows. Use a computer that has a video card so
you can connect both displays to the computer. Connect the
known-good display to the built-in monitor port; connect the
1710(AV) display to the video card connector.
2 If the problem involves a partially visible screen (you can
see the screen desktop and read the screen icons), there is no
need to connect a second display.
3 Turn on the computer and the monitor(s). If using a second
display, confirm that the known-good display is set up as the
main startup screen (Monitors & Sound control panel).
4 Open the application called Display Service Utility (from the
Diagnostics Utilities folder on the Service Source Companion
CD).
5 Select AppleVision 1710/1710AV pattern selections.
6 Click Create File. A message appears explaining that the
process will take about 3 minutes.
