This is where the confusion began: normally, any display I've worked on would turn on and stay on without any complaints after bypassing its protection (even if something started getting hotter than it should), but this one no longer came on AT ALL after pulling pin 1 to ground (not even briefly like it did without the strap to ground). When faced with faulty backlights, the first thing I usually do is bypass the protection of the driver IC (a SEM2005 in this case) by shorting the appropriate pin to ground (in this case pin 1). I immediately knew what was going on and went straight to the backlight portion. The chap brought it in saying that it would only stay on for a few seconds then go dark again. I've got this Samsung p2770hd with a strange backlight problem.
