This section describes how to determine if the computer’s display is functioning properly.  
The process is outlined in Figure 2-3. Start with Procedure 1 and continue with the other 
procedures as instructed. 

Procedure 1:  External display check 

Procedure 2:  Diagnostic check 

Procedure 3:  Connector and replacement 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. 

 

The Display Test program is stored on the computer’s Diagnostics disk.  This program checks 
the display controller on the system board.  Insert the USB memory disk in the computer, 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.
