I brought my super Nintendo in last night because I thought my AV chord was not working. You guys cleaned all the games, hooked up my chords and said everything was fine. However, when I get it home, it wont work and I tried two TVs. What's wrong?

when I went into the store they didn't have a converter, they plugged the white, red and yellow cables into the back of the TV and it worked fine. I get it to my friends house last night and nothing!

Do you have the tv on the correct input? Is the AV cord plugged into AV input and not a composite input? Most flat screens no longer have AV connections since HDMI is faster and more pure, some people make the mistake of plugging it the into the composite input, which will not give a picture. There are also AV converters for HDMI you can buy via Amazon. Just search for :RCA to HDMI convertor. They run $10-$20

You should bring it back in for troubleshooting, diagnosis can't be made any other way. If you can't make it in, at least try calling the store and talking to an owner/manager.

I would bring it back in to tje store with your receipt for repairs and cleaning. The have a television to test everything on. Would be your best bet.
