does the disc drive start moving with a disc in it? If it stays powered with the fan on I doubt its anything to do with the power supply. It could be a loose LCD flex cable laptops tend to have LCD connection problems after years of use. Try connecting it to another monitor with a VGA cable if it has a VGA output to project to another screen. If that works then its the LCD. If not then it could be a fatal motherboard issue.

It could be a loose LCD flex cable, laptops tend to have LCD connection problems after years of use. Try connecting it to another monitor with a VGA cable if it has a VGA output to project to another screen. If that works then its the LCD or the flex connection. If not then it could be a fatal motherboard issue.
