Question about HP w1907 LCD Monitor
I'm working on exactly this board right now, same problem. Two of the capacitors (c822 and c824, right at the top edge center of the board) are bulged and blown, causing my power-fail situation. They're available for about thirty cents a capacitor from any specialty electronic place. Piece of cake to solder in with the right tools and a bit of care. Hope it might be another clue to your problem. Good luck.
