Display Troubleshooting
This section describes how to determine if the T2100/T2105 Series computer’s display is
functioning properly. Start with Procedure 1 and continue with the other procedures as
instructed.
Procedure 1:
Contrast Control Check (T2100/T2100CS only)
Procedure 2:
External CRT Check
Procedure 3:
Diagnostic Test Program Execution Check

Procedure 5:

Procedure 1
Contrast Control Check (T2100/T2100CS only)
Contrast is changed by the contrast dial. If the contrast does not change when you turn the
contrast dial, perform Procedure 2.
Procedure 2
External CRT Check
Connect the external CRT to the T2100/T2105 Series computer’s external monitor port, then
boot the computer. The computer automatically detects the external CRT even if Resume
mode is enabled.
If the external CRT works correctly, the internal LCD display may be damaged. Go to
Procedure 4.
If the external CRT appears to have the same problem as the internal LCD, the display
controller may be damaged. Go to Procedure 3.
Procedure 3
Diagnostic Test Program Execution Check
The Display Test program is stored on the T2100/T2105 Series computer Diagnostic Disk.
This program checks the display controller on the system board. After loading Toshiba MS-
DOS, run the Diagnostic Program. Refer to Chapter 3,
Tests and Diagnostics
, for details.
If an error is detected, go to Procedure 4. If an error is not detected, the display is function-
ing properly.
