If Your PC Workstation Has a Hardware Problem

If Your PC Workstation Has a Hardware Problem
This section describes what to do if you have problems with your
display, disk drives, printer, accessory boards, keyboard, or mouse.

If Your Display Does Not Work

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:
1 Check that the brightness and contrast controls are properly set.
2 Make sure that the display is plugged in and switched ON.
3 Ensure that the display video cable is correctly connected to the
display and to the PC Workstation.
4 Switch off the display, and unplug it from the power outlet. Examine
the video cable pins to see if they are bent. If they are, carefully
straighten them.
If the display image is not aligned with the screen (usually when you
change resolutions), use the display's controls to center the image.
Refer to the display manual for instructions.
If the screens generated by your software applications do not appear
correct, check the application's manual to find out which video
standard is required. Also check your display manual to find out which
refresh rate is required. Use the HP Setup program to select the
correct refresh rate.
If the display works correctly during the Power-On-Self-Test (POST),
but goes blank when the operating system starts, restart the PC
Workstation and check that the amount of video memory detected by
the POST is correct.
