Did I fry my system?

[sbd_pker]

I accidentally plugged the wrong power cord into my Sega Master System. It was 12v instead of 9v. I just cleaned it out, and it worked fine after that, but after checking a cleaned game, I plugged the wrong power supply in, and now it won't turn on. Is there anything I can do? Thanks.

Might want to check this out.

I would take a multi-meter and narow down the power break. Might just be this fuse.

Thanks for the help. Unofortunately, I do not know enough about electronics, nor do I have the necessary equipment for that.

Where are you located? If you're in the Dallas area you can stop by with it and I can check the fuse.

I am in Oregon . I appreciate the offer though.

You probably blew the voltage regulator. It will likely need to be removed, and a new one popped in.
