Epson LT-286 - Manual (Page 116)

WARNING
When you turn off the computer, always wait at least five
seconds before turning it back on.. You can damage your
computer if you turn it off and on rapidly.
2. If the Power/Speed light still does not come on, turn off the
power switch. Check to see that the AC adapter is securely
connected to both the computer and an electrical outlet. Make
sure the green LED on the AC adapter is illuminated. Then
turn the power back on.
3. If the computer still does not start up, check that your electrical
outlet is working by plugging a lamp into the outlet and turning
it on.
4. If the electrical outlet is working and all the connections are
secure but your computer still won’t start, contact your Epson
dealer.
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 contrast switch and the brightness switch to adjust the
screen display.
2. To save power, the LCD screen turns off automatically after a
specified period of time. If this happens, press any key to restore
the display. To change the time limit or turn off the light-off
feature, see “Backlight Period” in Chapter 2.
3. If you still don’t get an image on the screen, check to see that
DIP switch 4 above the keyboard is in the on position to select
the LCD screen as the display device. Also be sure that DIP
switch 5 on the back panel is on. (See “Setting the DIP
Switches” in Chapter 1 for instructions.)
