if your graphics card has an advanced properties dialogue, bring it up and adjust the gamma. I ran into this problem with an old emachines monitor, I sent it back to the factory after it fried. They sent it back, still didn't work, went through this about 3 times, and finally, it turned on, but it was dark, too dark. Oh, and if your graphics card doesn't have an advanced properties dialouge, you can usually pick one up off the net. Adobe sends a good one out. GOOD LUCK!!!
