3Turn the display off and then turn it back on.
4Connect your system to another Planar 17.4 display, if one is available. If the system functions properly with the alternate display but not with the original display, and the original display’s power LED is blinking, the output timing of the computer’s video board may be out of the display’s synchronous range. Change to an alternate mode (1280 x 1024, or less), or connect to an alternate video source and repeat steps 1 and 2.
5Ensure that the computer’s video port is enabled (DVI or VGA). This is a function of the video board in the user computer system. See your system’s video board documentation for instructions on how to enable the video port.
6If the system does not function with either display, get help from technical support at your system provider.
