US SNES Jr with the wrong/too much UK voltage :(
Hello everyone,
I don't know if anyone can help but I thought I'd give it a try - I have an American NTSC Super Nintendo Jr, the redesigned unit released in the US only. It runs on 850ma DC10v on an AC adapter and I've put 800ma 12v into it. Ordinarily that would work fine as a previous power adapter ran it without problems. However that adapter busted a while ago and I recently obtained a new one - however I think I've put the wrong polarity into it and now it won't boot up under any circumstances. I'm not very technically minded and can't even begin to fix it. It's a fairly rare and expensive machine and although I've been able to open it up, I don't know what to repair or replace. Does anyone have any suggestions at all how I could fix it or where I could take it to be fixed? Any help at all appreciated, Schnide |

I don't know games at all, but... Is it possible that when the adapter you were using "busted" that it took the game itself with it? And why would you use 12 volts when you know the game wants 10? Isn't that kind of begging for trouble? Ken |

If it's like the 8 bit NES, it has an internal 7805 regulator (though the NES also had a bridge rectifier so polarity is not an issue), it's very possible that you simply cooked the 7805, look for a 3 pin TO-220 device near where the power comes in. |
