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.
If Your Display Does Not Work
If nothing is displayed on the screen, but the PC 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.
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.
5
Make sure that an accessory board does not use the same I/O address
as the integrated video interface (03B0h to 03DFh). Refer to the
documentation supplied with the accessory for more information
about the I/O addresses used by it.
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 the 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 SETUP or the HP User Tools to select the correct
refresh rate.
