3.1.3 Display Error Codes
Error codes are displayed on the left side of the LCD as shown in Figure 3-2. If an
error is detected the appropriate error code is displayed on the LCD. There are
three error codes:
E1 Power supply error (continuously checked)
E2 Signal path error (checked only during self test)
E3 NOT OK error (continuously checked).
The Maintenance and Troubleshooting section, Section 4, contains information
about how to resolve these errors.
Figure 3-2: Location of Error Indicators.
Error code E1 indicates a power supply error. The regulated power supplies inside
the 1900/27 monitor are continuously checked. If they fall outside of the
acceptable power supply range the monitor displays the E1 error code. An E1 error
could be caused by a poor power source external to the monitor, or a fault could
exist within the monitor itself.
