This section describes what to do if you have problems with your display, mass
storage devices, printer, accessory boards, keyboard, or mouse.

Display Does Not Work

NOTE
If the HP NetServer has a large amount of memory installed, it
may take one minute for the first screen to display.
1. If nothing is displayed on the screen, but the HP NetServer starts and the
keyboard, flexible disk drive, other disk drives, and other peripheral
devices seem to operate properly, do the following:
Verify the monitor is plugged in and power is turned on.
Verify the brightness and contrast controls of the display are properly
set.
Verify the display video cable is securely connected to the NetServer.
Turn off the display and NetServer, and unplug each power cord from
the power outlet.
Disconnect the video cable from the NetServer and examine the video
cable connector pins to see if any are bent.
If you find bent pins, carefully straighten each one.
Reconnect the video cable and all power cords and turn on the display
and NetServer.
If you have manually configured any accessories, verify none use the
same I/O address as the integrated video interface (03B0h to 03DFh).
Refer to the documentation supplied with the accessories you
configured for more information.
2. If the display image does not align with the screen (usually after you have
changed the resolution), use the display's controls to center the image.
Refer to the display's manual for information about the controls.
3. If the screens generated by the applications do not look right, check the
application manual to find out which video standard is required.
4. If the screen goes blank after the HP NetServer has booted, contact your
HP support organization.
5. If the screen is blank, video blanking may be enabled.
