So, my board arrived, I was planning to just experiment with it as a media center running XBMC. I got a 5V 1.2A charger, tested the board with nothing else plugged and the red led was on. Got a 2gb SD, downloaded and installed the raspbmc image to it, plugged the network cable to my router, I wasn't in the mood to get the TV, so I used an USB video capture device and the RCA video output with the computer.
With all set I powered it on. I didn't pay attention to the leds, but I got the rainbow splash screen stuck. I realized I forgot the keyboard, powered it off, got the keyboard, plugged it, powered it back on, and the board seemed dead. The red led would turn on, but nothing else. I unplugged everything, tested the supply voltage, still on 5V, but strangely, the 5V GPIO output was down to 3.6V, and the 3.3V was down to 2.2V. I noticed the F3 fuse was very hot, unplugged power and measured it to 2.6 ohm. After about 1 hour I plugged it back on and measures the fuse voltage drop, almost 2V! Also, not even the red led turned on. After a few minutes I tried again, the red led gave a faint light and went dead again.
Any ideas on what to do, or is there any clear sign that my board is dead? From what I read around the forum, the red led shouldn't be always off even if the fuse or the 3.3V regulator is blown. Should I leave the board for a while for the fuse to reset? Power using the GPIO?
