This section lists some basic checks you can do for most monitors. Check the docu-
mentation that came with the monitor for fault indications and troubleshooting
procedures specific to your monitor. If you purchased the monitor from Dell, you can
also find troubleshooting information on Dell’s World Wide Web site
(
http://support.dell.com ).
If you have no picture, try the following checks:
Make sure the power button is completely depressed (a click is heard when the
button is pressed).
If the power indicator is lit, turn contrast and brightness to their maximum
settings.
Turn off the computer system, and reseat the power cable to the monitor and
electrical outlet. Verify that the video-interface cable connector is firmly attached
to the video card connector and secured with the captive screws. Then reboot
the computer system.
Diskette-drive access
indicator The diskette-drive access indicator should quickly flash on
and off when you access data on the diskette drive. You
can test the drive by inserting a diskette in the drive,
double-clicking
My Computer , and then double-clicking
the icon for drive A. If the diskette-drive access indicator
does not light up, refer to “Drives” found later in this
chapter.
Hard-disk drive
access indicator The hard-disk drive access indicator should quickly flash
on and off when you access data on the hard-disk drive.
You can test the drive by double-clicking
My Computer
and then double-clicking the icon for drive C. If the hard-
disk drive access indicator does not light up, refer to
“Drives” found later in this chapter.
Series of beeps Refer to “POST Beep Codes” in Appendix C.
Diagnostic code Refer to “Diagnostic Codes” in Appendix C.
Unfamiliar constant
scraping or grinding
sound when you
access a drive Make sure the sound is not caused by the application pro-
gram you are running. The sound could be caused by a
hardware malfunction. See Chapter 7, “Getting Help,” for
instructions on obtaining technical assistance from Dell.
Absence of a familiar
sound When you turn on your system, you can hear the hard-
disk drive spin up, and the system tries to access the boot
files from the hard-disk drive or the diskette drive. If the
system boots, refer to “Running the Dell Diagnostics”
found later in this chapter. If your system does not boot,
refer to Chapter 7, “Getting Help.”
