REALLY NEED HELP!

Ok, here's what happened.
This is totally my fault because I was being stupid but what happened was my family went on Vacation to Cuba. Stupid me, I didn't look at the outlet saying 220V so I plugged it in and played it. It played for 10 minutes then something inside went "Bang" and smoke came out of it. However the game continued to play even after the smoke. I turned it off and looked at it. Looked like nothing wrong. I opened it up and there is nothing burned inside and it looks fine. WTF? If anyone knows what this could be please tell me. Is it a fuse, IC Chip, Capacitor. Tell me if this happened to you. Please if you have any information post it, thanks!

similar thing happened to my xbox. mabey the powersupply is just barely hanging on.

I want to make sure that my system doesn't become a fire hazard because that's what happened to his Playstation 2. Long story short, it set his house on fire! But anyway please help...if you can :)
