Tips for a great answer:
Shine a flashlight on the dark screen to see if you barely
see the icons on the desktop. If so, then the LCD Inverter is bad.
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 so that proves your video card is ok. 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.
If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

The Intelli-Check™ Filter Monitors will indicate replacement of the pre-filter and the
HEPA filter. Depending upon your individual usage (environment and hours used),
you may need to check and replace the filters more or less frequently.
To check Expected Filter Life Usage
When the unit is turned on, quickly press the appropriate filter monitor button. The
pre-filter light will flash up to 3 times and the HEPA filter light will flash up to 4 times,
depending upon how much expected filter life has been used.
1 flash = from new, up to 1/3 expected life used up
2 flashes = between 1/3 and 2/3 expected life used up
3 flashes = between 2/3 and all of expected life used up
Remains on = time to check/replace pre-filter
1 flash = from new, up to 1/4 expected life used up
2 flashes = between 1/4 and 1/2 expected life used up
3 flashes = between 1/2 and 3/4 expected life used up
4 flashes = between 3/4 and all of expected life used up
Remains on = time to check/replace HEPA filter
To RESET Filter Monitor
When the filter monitor light remains on, it is time to check/replace the filter and reset
the filter monitor, if needed. With the unit powered on, press and hold the appropriate
filter monitor button down for approximately 5 seconds until the light turns off.
