My aunt gave me her old nes, it was really dirty. I opened it up, cleaned it really good, cleaned the games too. I had to get a new power pack and av cables for it. I plugged everything into my TV (had to plug it into a mini av to hdmi adaptor) every game I test it with gives me the red blinking light, than when I press reset a image pops up, but there's random white bars going down the screen. I've done some research and I think it's the 72 pin connector, but I've looked at it and none of the pins are connecting. I also have trouble with the nes loading without controllers, whitch is odd because the nes has to have a controller in it to load properly.
UPDATE I put in a different 72 pin connector out of a old nes, I'm still having the same problem. I think both pins have been pushed down after games have been left to sit for too long. Would Boling fix that? Or should I just buy a new pair off amazon?
