Mr L33t's monitor is secure again. Somehow, over the last week or so the stand had snapped and the screen was balancing precariously on the pylon. Any light touch would send the whole thing crashing down on the keyboard. Thankfully, I have the reflexes of a 10 year-old for catching things... like measles, mumps and chicken-pox, and so I've managed to avert total disaster.
Not trusting my luck for too much longer, I brought it to the local Samsung customer service facility. It appears they don't get too much experience fixing simple mechanical problems like this one. Selling me a replacement mounting strut was easy: $5, please. The next thing was the proper procedure for helping me install it since part of the original strut was still stuck inside the housing.
After a bit of ding-dong with the retail guy, the service girl and the unseen backroom tech, they eventually decided not to charge for the extra service -- the service of removing the entire back panel in order to jiggle out the remnant piece before installing the new part.
In case you are wondering how a monitor could possibly snap off its support stand... it's a mystery to me too. It definitely has nothing to do with the time I had finally, after several frustrating attempts, delivered the killing blow to the Prime Evil on Nightmare mode, the Diablo servers went down for maintenance right at that very instant. I swear it was broken before that.
