I have a Samsung SyncMaster 931BF. I love the screen, but for quite awhile, the screen has been having a hard time coming on and staying on. I'll have to cycle the power multiple times to get the screen to stay on and it's getting really bad now. I have read that the problem is either capacitors, the power supply, or the backlight, with it most likely being capacitors. My problem is that I can't figure out how to get the screen's case to open to see inside! I have tried everything in the repair manual (the actual manual technicians use) and unfortunately, it doesn't just "lift off" b/c it catches on something inside. Anyone know how to open the dang thing up?!?

Remove its stand
Unscrew all the screws in the back.
It doesnt just lift off I guess you could say, there are many clamps around the edge that need to be "popped" by sliding anything thin enough to get between the front and back of the case to pop them.

I popped mine open the other night. The clamps appear to be hard to break, at least in my circumstance. None of them broke with a fair amount of pressure from pulling being applied.

Also, mine had your exact same issue until one day it no longer turned on completely. It just flashed the screen once and showed a flashing power light around the button. Replacing 3 capacitors that were just barely bulging on the top fixed the issue.
