 off. It has four switchesd below the screen, labeled 1, 2, an up arrow,

 When I plug it in, it flashes Red, Blue, Green, White at about one-
 second intervals. Pushing the buttons doesn't affect it.
 I haven't attached a VGA or DMI to it.
 Is it irreparably broken? 
Short answer--no, it's not irreparable if it's showing life.
This sounds like a power supply issue, but that's just a guess.
