3 Troubleshooting Your PC Workstation
If Your PC Workstation Has a Hardware Problem
If Your Display Does Not Work Properly
If Your Display Is
Blurred or Unreadable
If you have selected the wrong display, the display screen may become
blurred or unreadable. To correct this problem:
•
Select the correct display by referring to the display options section
in the HP-provided online user setup information that came with
your PC Workstation.
•
Alternatively, select the correct display by using the procedures in
the operating system on your PC Workstation. Refer to your
PC Workstation’s operating system documentation for details.
If Nothing Is Displayed
On the Screen
If nothing is displayed on the screen, but the PC Workstation starts and
the keyboard, disk drives, and other peripheral devices seem to operate
properly:
•
Make sure that the display is plugged in and switched ON.
•
Check that the brightness and contrast controls are properly set.
•
Ensure that the display video cable is correctly connected.
•
Switch off the display, and unplug it from the power outlet.
•
Disconnect the video cable and examine the video cable connector
pins. If the pins are bent, carefully straighten them.
•
Check that the video upgrade is properly installed if you have one.
•
If the display works correctly during the Power-On-Self-Test
(POST), but goes blank when Windows starts, check that you have
enough memory for the video mode you have selected. Boot the
operating system in VGA mode (available with some systems).
•
If your screen’s refresh rate is set too high, the screen might be
blank. Check the refresh settings to ensure they are not too high.
