Procedure 1
External display check
Connect an external display to the computer’s external monitor port, 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.

board may be damaged. Go to Procedure 2.

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,

details.
If an error is detected, go to Procedure 3. If an error is not detected, the display is functioning
properly.
