Can I.....
 

Can I get my nes fixed still or do I have to buy a used one. How much about do they cost?

Whats wrong with it? I fixed my own by just taking it apart and cleaning all the dust out.

maybe you can tall nintendo and get them to work on it ^^ they will prolly tell you how to fix it, or you will have to send it in and they will hook you up

You can call nintendo and send it in for a fix (about 50$) for a working unit returned...

Just buy a new one. eBay is there for a reason.
