Probably the infamous logic board problem. To confirm if possible hook up a external monitor. If you have video then the problem is most likely the LCD. No video you are most likely looking at a bad logic board. Sometimes you can get some use by putting a spacer under the video chip but it doesn't usually last for long. Ralph
