In that case, looks like the LCD is broken/dead. Did it just happen??? Was it banged, sat on???

What is the resolution that you have on the erxternal? It could be out of range from what the LCD can support, thus no screen.

cheers ...

I tried everything to test the resolution of graphics cards: from 800x600 to 1280x1024 pixels, without change.

could be a failure with the north bridge. on other models I have seen the same symptom. after I repaired the north bridge, internal video worked again.

I never seen the north bridge fail on a 5100, usually its the ati ixp 450 south bridge that fails on these models...
