procedures below as instructed.

Procedure 1
External Monitor Check
Connect an external monitor to the computer’s external monitor port, and then boot the
computer. The computer automatically detects the external monitor
when “Power on Display” setting is “Auto-Selected” (Default) in BIOS Setup Menu.
If this setting is “System LCD only”, external monitor cannot be displayed.
If the external monitor works correctly, the internal LCD may be faulty. Go to Procedure 3.
If the external monitor appears to have the same problem as the internal monitor, system
board may be faulty. Go to Procedure 2.
Procedure 2
Diagnostic Test Program Execution Check
The Display Test program is stored in Diagnostics disk. This program checks the display
controller on system board. Insert the Diagnostics disk in the USB FDD, 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.
