Has anyone else replaced the 72 pin connectors of their NES with a new one?

I've replaced the connector on 6 Nintendos, they all originally worked better, but still have problems. The four I had wouldn't even work before I replaced them. Of the replacements, two quit working entirely, two work sometimes, and two work fine. Four of these were completely refurbished. I took two back and they got the second set of pin connectors, and they worked good for awhile. On the other hand, I've had three Nintendos, with the original pins that worked fine. It's hit and miss. I didn't play a lot of Nintendo back in the day (I went from Atari To Genesis) so I didn't realize the enormous rate of malfunctions the Nintendo had. My brother's original Nintendo from 1990 quit working last January, and has had two sets of new connectors. It still doesn't function properly. My ex-wifes Nintendo from 1988, quit working about the same time, and it too has issues, but works better than his.
For example, today I was playing a non-alterted Nintendo, some games worked, some didn't, but when I was playing Ninja-GAiden, after about fifteen minutes, the screen rebooted, and started blinking. I have never seen that before.

I also have a retron, and sometimes games won't run on that, so I don't always know if its the game, the system or both.

On the other hand, I haven't had any problems with my other systems.

Yeah, NES systems can be hit or miss in working properly. If the game library wasn't so strong, most folks probably wouldn't bother with it because it can sometimes be a hassle.

I would reiterate that if you're going to replace a pin connector make absolutely sure that it's one marked "Made In Taiwan". I replaced 23 pin connectors last year when I was creating and selling custom NES systems. Tried the cheap ones are first and it was a total toss up as to weather they worked or not. The "Made In Taiwan" ones were solid. Of the 23 I replaced, I only receive one that gave me any issues after being replaced and I suspect that was more corrosion on the motherboard itself than it was the pin connector.

Also make sure to clean the contacts on your games. Frankly, that's probably the most important aspect of getting a NES game to play and the first thing that should be checked if a game isn't working. There's various methods that work well. Isopropyl Alcohol, Q-Tips, and a pink eraser worked best for me.

I changed my 72 pin connector and it worked like a charm, the games seem to "click" in much more snugly and they work properly. If a game doesn't work for me it's 100% because of dirty connectors on the cart.

I switched mine out, and for some reason the cart no longer pushes down - like it's stuck in the up postition. need to open it back up and see what's jamming it, but not got around to it.
