The lcd screen or video card inside the computer is going bad. To
isolate the problem connect an external monitor to the laptop. Borrow a
monitor from a neighbor, friend, relative or co-worker to connect to
the laptop.
Plug in an external monitor and see if
the
display shows up on it. It can be any kind of monitor even the old big
fat crt
monitors as long as it has a vga cable to connect to your computer's vga
port. If the external monitor displays without a probem that proves
your video card is ok and your lcd screen is going bad. If the external
monitor displays by fading in and out like your lcd screen, then your
video card inside the computer is going bad.
The video will show
on most systems when you reboot without you having to do anything. Some systems
will require you to hit the FN (Function key) + F1 thru F12. Hold down
the FN key then hit the correct key for displaying on the monitor (F1 thru
F12). The correct key will normally have CRT/LCD on it or it will have
the icon of a display.
