Well allow me to hijack this little nice thread and ask the same. I have a NES that doesn't power up, i made a mistake and a little nobrand power adaptor fryied the system or maybe i didn't power it again after i have unplugged it from the wall like the snes system to drain the power from the board, before i start to clean the inner parts of the system. Well is there any kind of fuse that i can change to make the NES fully operational. Thanks.
