NES help?

[understatement]

Does it have the original power cord or an aftermarket one? Some problems can occur with aftermarket power cords being plugged in to a surge protector they work better being plugged right into the socket.

Also if he used a cheap “new pin set” it could cause this type of problem or if they didn’t put the system back together right, the tray that holds the games has a lip that goes under the motherboard but a most of time people don’t realizes it and just slide it in on top of the motherboard causing games to not work properly or at all.

Personally if I bought it from a store I would take it back with the offending game that causes the lines and see if it does the same thing at the store if it does get them to replace it, fix it, or refund it.

It seems to be the original power cord.. I mean, it says it was made by Nintendo, has the right model number, etc..
And I tested it at his shop before I bought it, and it worked flawlessly, no lines or anything.

Try it on a different TV.

A lot of modern flat screens don't like game systems from that era. If you have a CRT somewhere try that.

Does it have lines with every game? If it does than it might be the TV like Frankie says. If it’s only some games that cause the lines I would have to say it’s cheap pins or put together wrong. That’s why if you do take it back take a game that is causing the lines with you.

Also (you probably already did but) you can try cleaning the games more, an NES and a clone are different in where the pins connect at so the pins might be clean where they connect to the clone and not so clean where they connect to the NES.

Bad filter capacitors can do this, too. They can also cause a slight hum or buzz in the audio.

If it was put together wrong or a pin problem, wouldn't it do it with every game? Worked flawlessly at the store -- I'm beginning to think the games just need more cleaning...maybe some alcohol or something.
The TV is fairly older. It's a CRT. I don't bother with flat screen TVs if I don't have to.

If all games worked flawlessly in the store, and all games have wavy lines at home, I'd bet safe money that your TV doesn't like the NES.

Cleaning the games doesn't typically help with video output issues unless you're talking about graphical "glitches" that could be the product of the 72 pin connection not completing properly to transmit data. But "wavy lines" sounds like a video output issue.

Again, try a different TV and see what happens.

I also tried with both the composite cables and an RF cable, and they were both giving this problem - though if it was a problem with the TV "liking" the NES, that would make sense, wouldn't it?




As for more games using more pins than others (like the other guy was saying), the game I tried it with in the store didn't have pins all along the bottom of the cart (DK classics) and both of mine that I tried (SMB and Elevator Action) did, so that also makes sense...

It depends what game it is and how bad the bind is on the motherboard. Not every game uses the same pins some use more some use less. If the lip is on top of the motherboard it raises the cart slot up about half an inch in the middle so the pins on top might get a good connection but the ones on bottom and edges might not connect so well resulting in glitches or not working at all. So a game that only uses the pins in the middle might work fine and a game that uses pins on the edges might glitch out.

Also when this lip is on top of the motherboard it bows the motherboard as well and that can cause problems. This is how the lip should look from the bottom of the motherboard.
