I had a similar problem- my power LED would just continue blinking when connected to a 5V power source. This meant there was something wrong. First, I checked if my BBB was still alive. To find that, I connected my board to a computer via USB. Surprisingly, this time power LED turned on normally. Then to make sure that everything was properly, I ran some program as given in the BB website http://beagleboard.org/getting-started. I was happy to see, the programs on the website worked just fine on my board. Thus, I was able to conclude that strangely, my BBB board didn't like 5V external power source!
