My Inspiron is ill. I have tested the screen on a different laptop and it works fine. I resat and then replaced that video card. I can hear the machine is on and running and you can actually find the log in button and get into the desktop. But you cant see anything. The screen stays completely black the entire time. Any ideas on whats going on and how I can fix it?
When you tested the screen did you test the cable/ribbon, and the inverter, or just the screen by itself? If not it could be the cable or the inverter. If you did test these, then you might lean towards the connector on the motherboard, or a trace that leads to the connector. Also, have you tested the machine on an external monitor? I know Dell has some diagnostic tools to download from their support site. You might try this as well. The diagnostic tool and the external may reveal some clues to exactly what's going on. Try these and let me know.
It could be either of these two:

I think I would contact Dell's customer service before buying and changing any parts. I have been told Dells online live tech service is very helpfull.
