Hey Jacobo . From what I'm seeing here, you have blown the metal-oxide varistor (MOS) (the light brown ceramic capacitor looking thing), which could be your savior. It's designed to protect against excessive over voltages. To fix it, you'll need to buy a new one and replace it. I'd also replace the EMI suppression capacitor (the big yellow capacitor behind the MOS), as its physically damaged. This guide shows you how to solder and desolder; [guide|750]

Just as a precaution, I'd test the big brown ceramic capacitor behind the EMI suppression capacitor, the 47 ohm resistor and the voltage regulator at the least. As for if you can convert it to accept 240VAC, no. The board is built to only take 120VAC and as its power supply is only a linear one. You'll need to buy a 120VAC - 240VAC converter.

This guide covers testing capacitors; http://www.electricaltechnology.org/2013/06/how-to-check-capacitor-with-digital.html#

This one covers resistors; https://www.google.com.au/webhp?sourceid=chrome-instant&rlz=1C1AFAB_enAU495AU496&ion=1&espv=2&ie=UTF-8#q=test%20a%20resistor

and this one (though harder) covers the regulator; http://www.learningaboutelectronics.com/Articles/How-to-test-a-voltage-regulator

I hope this helps you out or at least sets you in the right direction. If you have any questions, please feel free to ask.
