Procedure 1 External display check
Connect an external display to the computer’s external monitor port, and then boot the
computer. The computer automatically detects the external display.
If the external display works correctly, the internal LCD may be damaged. Go to Procedure 3.
If the external monitor appears to have the same problem as the internal monitor, the system
board may be damaged. Go to Procedure 2.
Procedure 2 Diagnostic check
The Display Test program is stored on the computer’s Diagnostics disk. This program checks
the display controller on the system board. Insert the Diagnostics disk in the computer’s
floppy disk drive, turn on the computer and run the test. Refer to Chapter 3, Tests and
Diagnostics for details.
If an error is detected, go to Procedure 3. If an error is not detected, the display is functioning
properly.
