Epson 4SLC2-50 - Manual (Page 105)

The LCD Screen Is Blank
If the computer starts up but no image appears on the LCD screen,
follow these steps to solve the problem:
1. Use the brightness and contrast controls to adjust the screen
display.
2. To save power, you may have set a time-out period for the LCD
screen in the Setup program or with the VGACONF utility.
This turns off the screen automatically after a specified period
of time has elapsed with no keyboard input. Press the shift key
to see if this restores the display. (See Chapter 5 for
information about the power management options, and
Chapter 6 for information about VGACONF.)
3. Make sure the suspend/resume switch is set to the left. The
computer may just be in Suspend mode.
4. If you have connected an external monitor to your computer
and you are using it, you should not have any problem
displaying information on both screens at the same time.
Check your VGACONF settings; see Chapter 6 for details.
The External Monitor Screen Is Blank
If you are using an external monitor and no image appears on its
screen, follow these steps to solve the problem:
1. Make sure the power switches on the computer and the monitor
are turned on.
2. Adjust the brightness and contrast of the monitor screen.
3. Make sure the monitor is set to the correct input. Some monitors
can accept input from two sources.
