LCD blinks for "a couple of minutes" after turning it on.
I had this screen for about three years and its suddenly gone mad ;).
When i turn it on it just blinks, showing a black screen and my desktop. After a couple of minutes it works like a charm.
Same problem on DVI/VGA and on three different machines.
I guess it's kinda obvious what's going on -- just not to me :<.
Is there anything simple to fix it?
It's a well known problem and 3 years is about the time it starts on certain Samsung models (or even all models within a certain timeframe). The issue is the capacitors, they are from a sub par batch. Check out the youtube vids: http://www.youtube.com/watch?v=0hp1xF6eP... ...On the right hand side of the page and it will become clear, even how you can fix it!
Mine was a SyncMaster 226CW me thinks.
I fixed two Samsung 225bw lcds with this problem, by replacing three capacitors each (about $5 value total).
You can do the same, if you have a soldering iron, though it is not a difficult job. I found helpful information at: http://www.badcaps.net/forum/
