I would first evaluate the situation. If the pins are clean on the inside, try thepin-bending technique. If that doesn't work, try FABombJoy's aforementioned technique. Then (and this is important, too), post back here so people can know how it went.Originally Posted by grimlock16
Note that I'm assuming your NES doesn't work ever--the blinking screen syndrome, yeah, you know. If it works sometimes, it may be the carts themselves.
So personally, I wouldn't ever buy a replacement MCM pin set after hearing omnedon's testimonial; it seems the better choice would be to do what he's doing now, refurbishing pin sets from other NES's.
