2.If the power switch is on but the power light is not, turn off the monitor’s power, wait five seconds, and turn the power back on. Wait a few seconds to see if the screen displays any text.

3.If the monitor’s power light still does not come on, check the electrical outlet for power. Turn off your monitor and unplug it from the wall outlet. Plug a lamp into the wall outlet, and turn it on to see if the outlet supplies power.

4.If you still do not see anything on the screen, make sure your monitor is connected to the computer properly. See “Connecting the Monitor” in Chapter 1 for more details. Also check the monitor manual for directions on connecting it to the computer.

5.If you are using the MGA card in your computer, make sure the color/mono switch on the back of the card is set correctly for your monitor. See “Connecting the Monitor” in Chapter 1 for instructions. Also check DIP switches 1-5 and 1-6 on the front panel of the computer to make sure they are set correctly. See Appendix A for instructions on setting the DIP switches.

Note

Many monitors display in only one color (such as green

or amber), but they are not necessarily monochrome

monitors. If your monitor is not specifically a

monochrome monitor, set the color/mono switch to

color. Check the documentation that came with your

monitor to verify which type it is.

6.If you are running an application program, check to make sure the program is set up for the type of monitor you have. Occasionally, programs need to be set up specifically for the type of monitor you are using.
