Does it mean an external monitor is still attached when you tried the 2 things you noted above? Try removing the LCD video cable from the system board/motherboard and run totally on external monitor. Observe if monitor turns black in a few minutes (use Knoppix still).

This is starting to sound like an intermittent hardware based issue to me. Any suggestions as to where to start. Inverter ? Video Chip, Memory. Does the video memory share RAM like on some desktops ? Thanks
