Im trying to fix the 72 pin connection on one of my toaster nes's. I bought a broken nes "that needs a new 72 pin" on ebay. Upon plugging it in i could not get any of my games to work - randomly colored screens and power-cycling (and yes, the games are clean. I have another nes that works great).
So i bought a new 72 pin, and that solved the power cycling BUT the screen would just be a random blue/green/pink color. However, MarioBros/Duck HUnt works fine... its the only game that works.
I thought it might be the motherboard connection. I tried everything. Eraser... rubbing alcohol, electrical contact cleaner. Doesn't do shit.
Any ideas? Please god don't tell me to clean my games. They are clean. Here are the key facts:
1. A new 72 pin made a difference (suggesting that there is in fact at least a problem with the connection)
2. The motherboard contacts are SHINY. I've seen dirty nes mobos and this is just as clean as my other nes that works.
3. One game works. My other two (shitty golf game and powerpak do NOT)
thanks...
UPDATE : Tried disabling the lock out chip. Didn't do anything...
