The computer automatically detects the external monitor.
If the external monitor works correctly, the internal LCD may be damaged. Go to Procedure

board may be damaged. Go to Procedure 2.

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,
