How difficult is it to replace a Samsung monitor power supply?

I have a nice 22” Samsung monitor...well, it WAS nice, when it worked properly. I am pretty certain it is the power supply (turns on, then turns off after a few seconds), but I haven’t confirmed that yet. How hard is it to replace a power supply, and is it worth it? Mine is out of warranty, so it’s up to me. I don’t want to spend too much time or effort; a new 24” Samsung monitor can be picked up for less than $300.

Your best bet is to contact Samsung and see if you can get a replacement, for free or for however much it costs. If it's too expensive, go with the new monitor.
It may not be your power supply, but it does sound likely. Power supply issues are most commonly caused by the cheap-o capacitors that they use to save a few pennies on each unit. You should be able to take it apart pretty easily. Look for bulging capacitors (they don’t always bulge when they fail, but often they do). You can buy new capacitors and replace them yourself for just a few dollars, so yeah, I would say that it is worth it if that is the problem and you have the skills. If not, it may not be worth the cost. To really test it, you need an ESR tester, which would negate the savings. I would probably take a chance and just replace all of the capacitors on the power supply. One thing to remember though is capacitors hold a charge and can shock the hell out of you even with the unit unplugged!
