The Monitor Screen Is Blank

If you are using an external color monitor and no image appears on its screen, follow these steps to solve the problem:

1.Be sure the power switches on the computer and monitor are turned on.2.Use the controls on the monitor to adjust the brightness and contrast.

3.Remove any diskette from drive A, then turn off the power switches on the monitor and the computer. Check that the monitor’s power cable is securely connected to the monitor and to an electrical outlet, and that the monitor cable is properly connected to both the monitor and the computer. Then turn both power switches back on.

4.Check that the CRT/LCD slide switch is in the CRT position. (See “Setting the Slide Switches” in Appendix A for instructions.)

5.Turn off the power switches on both the computer and the monitor. Then check the electrical outlet for power. Plug a portable lamp into the outlet and turn it on to see if the outlet supplies power.

6.If an image still does not appear on your color monitor, contact your Epson dealer.
