Computer monitor doesnt show anything?

My computer turns on but shows nothing on the monitor… Not even the no signal… Ive changed the video card, motherboard but still the same problem…

my motherboard is Asus P5Q Pro Turbo
Video Card : 8800 GTS EVGA
Processor: Pentium D Core 2 Duo ( dont remember the exact specs)
Ram : Muskin 4 GB

any things that i could try to solve this problem?
i tried hooking my tv up to it and still didnt work

the back light may have burned out…
