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!

 

Thanks!
