This section describes how to determine if the computer’s display is functioning properly.
Start with Procedure 1 and continue with the other procedures as instructed.

Procedure 1:  Diagnostic Test Program Execution Check
Procedure 2:  Connector and Cable Check
Procedure 3:  Fuse Conduction Check
Procedure 4:  Replacement Check

Procedure 1

Diagnostic Test Program Execution Check

The Display Test program is stored on the Diagnostics disk. Insert the Diagnostics disk in the
computer’s floppy disk drive, turn on the computer and run the test. Refer to Chapter 3,

Tests

and Diagnostics

for details.

This program checks the display controller on the main board. If an error is detected, go to
