Motorola Droid :: BLACK SCREEN / Screen Not Turning On?

So I recently have been having problems with my phone and its screen not turning on. Its the original droid and I guess alot have people have had this problem. But I am at a fork in the road:(this is the thrid time the screen has done this)Last night I went to check my phone and it appeared to be off, my power button does not work so I have to plug it in to turn it on. But the charger light was on so that meant the phone was already on. the buttons lit up still as well. Being this is not the first time I took the battery out for about an hour and put it back in, plugged it in, and still nothing. The M sign that comes up when you first turn it on doesen't appear and neither does anything else on the screen. But when i recieved a call I could answer the call like the screen was working but still was not on. I left the battery out all night from 8pm-6am and still nothing but i can still answer the calls. Left it out until 2 this afternoon and still nothing. I have no idea what to do.
