I have exactly the same problem with my D620 (with NVIDIA graphics) as described at the beginning of this thread. I am "lucky" enough to have two identical D620 so I could do some more testing. As follow I will call the working D620 as D620good, the one I am having problems: D620bad

I swapped the complete screen (including LCD, cable, inverter) with the D620good, and everything works just fine. This suggests (as the original poster) that the actual screen+cables are OK. I then mounted the screen of the D620good in the D620bad, and although I could see the backlight to power on, the screen remained completely dark. I tried all different combinations of cables+LCDs, with the same results.

So if there is a problem, I am inclined to think that problem is with the motherboard and specifically with the NVIDIA chip.

Any suggetions?
