My problem is related to this thread, but it's over a year old, and my problem is slightly different.
I have the same type of monitor (Samsung SyncMaster 2493HM) with the same basic problem: When I turn it on, I get no picture, but the LED remains a solid blue, which is supposed to mean that the logic board and power supply are working. I, however, don't hear a persistent clicking sound; I only hear one quick "click" when I touch the power button.
I received the monitor as a gift from a friend who knew I liked to repair electronics. When I first attempted to repair it about a month ago, I heard something come loose inside the case as I was about to open it. Rather than continuing to pry the monitor apart, I decided to plug it back in, and it worked! It continued to work without any issues until I went on vacation last week.
I was gone for about a week and a half, and the monitor was left sitting in my apartment (without air conditioning in Florida). Upon attempting to use it again, I have found that it is having the same exact problem it had when I first received it. I have now actually opened it only to find that all of the capacitors appear to be fine (no bulging whatsoever).
One thing I was expecting to find once I opened it was whatever had come loose originally; I found nothing. I removed the logic board and found that some component on it rattles when I shake it. I have no idea if this is the problem since it appeared to be present when the monitor was working.
I do not think that the capacitors are the problem, and I am hesitant to replace them because my current soldering iron is awful for desoldering (it can't seem to heat any solder through the desoldering braid).
I love this monitor... is it wrong to love a monitor? When it works, it is simply beautiful. My backup monitor is from ~2004 and is ugly by comparison, but at the very least it is reliable. I very much want to fix this, so if anyone has any suggestions, they will be greatly appreciated.

It may be that you just uncovered the problem rather than caused it, either way,damage is done and those transformers seem hard to get hold of. If you can get the rest of the glue off without causing any more damage it may be repairable- we would need close up pics to inspect.
