I was just wondering if anyone has replaced the 72 Pin Connectors on their NES? I want to replace mine (I have 2 Nintendo Entertainment Systems that are broken, got one off a friend for free ^.^) and was just wondering if it was easy. I haven't really done any mods on anything before, though I did fix my Starfox game for SNES. ^.^

I solved my problems cleaning connector using WD40.

I dont reccomend doing this, because that will just make things all oily. I reccomend using keyboard cleaner. (Aerosol Canned Air)

Yeah, I've used Canned air... Can't say that I have used the WD 40, but I'm a bit skeptical about doing that. Anyway, Its gotten to a point that the Canned Air really doesn't help much now.

I'm more interested in the Pin Connector.

Yes, I have.  Don't know if you've seen it yet or not, but I wrote an article about it here:

http://www.vintagecomputing.com/index.php/archives/13

I'd also advise staying away from WD-40, as yes, it is quite messy and it is not made for use with electrically conductive contacts.  I've heard about a better (and somewhat exotic) lubricant called 'Stabilant-22" for such a purpose, but aside from the name, I know nothing about it.

There is also supposedly a way you can "fix" the pins in your existing 72-pin connector by re-bending them by hand (with pliers).  Although I suspect that's only a temporary fix.

I replaced my 72-pin connector a few weeks ago, actually. Piece of cake. Just remember to put all the screws back.  :lol:
Like RedWolf's article says, the new connector will grab on to your games and will NOT want to let go. But over time, I suspect it will loosen up.

Question...I get the power light blinking on my broken NES, but I don't get any video out either. If I buy a new connector, will it fix that, or is my NES fried?

Is the TV completely blank, or does it blink white/black/white/black?

That's what I was about to ask.  Is there really no video, as in no signal whatsoever (there should be no difference on the TV between the NES plugged in or not, turned on or not), or do you just have a solid color displayed only or a blinking problem?

If you truly have "no video" then try the other video connector.  That is, if you're using an RF connection, try the composite video RCA connector.  If you're using the composite video connector, try the RF.  Also try a different cable.  Wiggle the connectors.  Let us know what happens.  Also, is this a toaster or a top-loading NES?

VCR style NES, and no video (black screen) on any connector...

Well, The original NES is the 'Toaster.'
Looks like this...


And the Top Loading one was a remake in the early '90s (92-93? not sure..)
Looks like this...

Hmm, doesn't sound good. Have you tried all the tricks of moving the cart while it's in the NES? i.e. sliding it to one side or the other, or re-seating it so the cart is inside the NES JUST ENOUGH to clear the door when you press it down?

(flashes back to my days of ISP tech support and asks the obvious question)
Is the TV turned on?

TV's on, I did everything you said, and it still doesn't work... Ehhh...

I'm going to rip out the 2A03, attach it to some sort of NES-on-a-Chip clone, embed MIDINES into it, and have a self-contained NES synth...

Yeah, I think the toaster is hosed. Replacing the 72-pin connector will do nothing.
Though your synth project sounds cool  Cheesy
