Monitor Problems
There is no display on the screen.
Check that the monitor’s power switch is on and that its power
light is on.
Also, the computer may be in low-power standby mode. When
you press a mouse button or a key on the keyboard, see if the
monitor displays an image.
The power
light
is on,
but you
still do not see anything on
the screen.
Press a mouse button or a key on the keyboard to see if the
computer is in low-power standby mode. Also, check the
brightness and contrast controls.
If you still do not see anything on the screen, make sure the
monitor is securely connected to the computer.
If you are running an application program, see if you need to
set up the program for the type of monitor and display adapter
you have. Also make sure you are using the appropriate
monitor and display adapter for your software.
The power switch is on but the
power tight is not on.
If the monitor is Energy Star compliant, it may be in low-power
standby mode. Press a mouse button or a key on the keyboard
to activate the monitor.
Turn off the monitor’s power, wait five seconds, and turn it
back on.
If the light still does not come on, check the electrical outlet for
power. Turn off your monitor and unplug it from the outlet.
Then plug a lamp into the wall outlet and turn it on. If the light
turns on, your monitor may be faulty.
