A question about my new NES.

Hey,So yesterday my cousin gave me his old NES, but it didn't work, it had a fuzzy white screen. So I took it apart and cleaned the connectors along the motherborad the connector for the motherboard and for the cartridge. I turn it on and it worked! But, there are alternating vertical lines running down my screen. Is this a problem with the RF Switch, which is set to the correct channel, or do I have to open up my NES again.

Your thoughts? 

From my experience there isn't too much science involved with troubleshooting the NES. Since cleaning brought it back, that may still fix the problems that you are having but I have also found that simply shaking the system can also effect the picture quality. You could also try using another cable to connect the NES to the TV which you could probably get dirt cheap on ebay. Ocelotpoo

This would be a composite video cable. That always made mine look good.
