LED light flashing- Monitor Blank but eventually comes on

I have a 3 year old 19 inch Medion flat panel monitor MD7319 which started acting up around two months ago. The first symptoms were annoying, but I could live with them. After turning on the computer, and then the monitor, the monitor's LED next to the power switch would begin to pulse, and the monitor would remain completely blank. Oddly, the little MS tune which plays on "bootup" would play, but only when the LED would pulse on. When the LED turns off, no music is heard. After less than two minutes, the monitor would finally just come on.
As the weeks have gone by, the monitor has taken more and more time to come on. I now have a replacement CRT monitor, but I'd like to try and fix my flat panel monitor.
Currently, I can let the flat panel warm up for around 10 min, and then if I punch the On/Off button quickly about 10 times, it will come up. I have taken the faulty monitor to another CPU and plugged it in. It behaves the same on the other computer as it does on my CPU. Unless I punch the on/off switch, the monitor will not now come on at all.
Here is a link to a tantalizing web page where people appear to have the same approximate problem as I do, and they appear to be solving it by installing capacitors. Unfortunately, they don't provide any pictures, so I can't figure out what they are doing.

Speaking of which, I have two pictures of the power supply board (correct term?) of my computer, which I can't figure out how to post here. One of the photos will show that there is a somewhat large capacitor with a white top which is wrapped in copper which appears to be leaning. Might that be a hint as to what the problem is? I'd appreciate any thoughts on how to proceed.
