Start with Procedure 1 and continue with the other procedures as instructed.
Procedure 1: External Monitor Check

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.
If the external monitor works correctly, the internal LCD may be damaged. Go to Procedure 3.
If the same problem as the internal monitor appears on the external monitor, the system board
may be damaged. Go to Procedure 2.

The Display Test program is stored on the computer’s Diagnostics disk. This program checks
the display controller on the system board. Refer to Chapter 3, Tests and Diagnostics for
details. If an error is detected, go to Procedure 3.
