If Nothing Is Displayed If nothing is displayed on the screen, but the PC Workstation starts and On the Screen the keyboard, disk drives, and other peripheral devices seem to operate properly: • Check your PC Workstation's LCD screen to help you diagnose the problem. • 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.
