Replaced logic board. IDE was bad.
Had video first booting. Froze.
When it froze mouse (which is lit) went dark. Keyboard would not respond. Tried plugging mouse into keyboard and logic board, still dark.
Had to powerdown with powerbutton.
Now no chime and no display. I know power is on because the power led on bottom (with user panel off) is lit and i can feel the fan through the top vent holes.
Tried resetting PRAM and PMU button. Screen is black but flashes when I hold powerbutton to turn off. Checked seating of videocard, just fine.
Checked to see if I screwed up video connector pins on logic board, still straight and connector connected properly and securely.
Thanks in advance.
