Alright, I think I know what the problem might be. I opened up the unit and I checked out the monitor connector and saw that some of the solder joints had over heated and melted together. Needless to say, this would more than likely generate problems for signal propogation; my exact problem. So, those of you with strange no signal problems despite the fact that you have a source; check out your LCD monitor jack, its probably messed up. Get a power regulator too! Hopefully I won't have any other problems.
