I have replaced the screen , the inverter board and disconnected the "screen close" sensor . I have also replaced the cables connecting the lcd to the board .
I still have the same dark screen .
If I connect an external monitor - everything works perfectly .
Somebody has told me about an "sm" cap that is next to a fuse and that we need to bridge the cap .

Anybody heard of this or have any other suggestions ?
