Hi all,


I have recently come across a unit that seems to power up but i get no image from the LCD or an external monitor. 


I did disconect the dvd drive and the fan on the motherboard came on, which is nice, but still no image.


My questions:


Is there a way to test (DMM) to see if the data video cable or inverter are the culprits?


Are they tests points on the logic board  I can measure to see if I can pinpoint what circuit is causing this behavior?


Any help or suggestions are greatly appreaciated!
