If Your PC Has a Hardware Problem
This section describes what to do if you have problems with your
display, disk drives, printer, accessory board, keyboard, or mouse.
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, try:
•
Select the correct display by referring to the display options section
in the HP-provided online user setup information that came with
your PC.
•
Select the correct display by using the procedures in the operating
system on your PC. Refer to your PC’s operating system
documentation for details.
•
In the HP Setup Program disable Display Plug and Play and set the
refresh rate of video modes to values supported by the display
connected to your PC.
If Nothing is Displayed on the Screen
If nothing is displayed on the screen, but the PC 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.
