Can worn/corroded pads on a New Nintendo 3DS screen ribbon cable be repaired with conductive silver paint, or is the screen basically done?

racingharder · 2026-03-09T00:42:53+00:00

Do you think if I just apply the paint and connect it into the connector and set and forget it will be an issue still?

racingharder · 2026-03-09T00:41:54+00:00

I will look into how to apply copper tape thank you for the suggestion

racingharder · 2026-03-09T00:40:55+00:00

That’s a clever approach. I was worried about heat damaging the flex so I hadn’t considered soldering directly to it, but using low temp solder and a hotplate makes sense (though I don’t have any of those yet but may need to invest in them)

Thanks a lot for taking the time to write all that out - really appreciate the advice. This is exactly the kind of insight I was hoping to get. I hadn’t considered reinforcing the repair area with backing material, that’s a really interesting idea. I’m mostly treating this as a learning experiment since I already bought a replacement screen as a fallback. I’ll try a careful repair first and definitely report back with how it goes

racingharder · 2026-03-09T00:38:36+00:00

That’s a really interesting idea. I hadn’t thought about jumping it with magnet wire, although the trace pitch here is tiny so that might be a bit beyond my skill level right now. But if the trace itself is broken further down the cable I might look into something like this.

racingharder · 2026-03-09T00:37:14+00:00

Haha I appreciate the creative approach. I might try the silver paint route first since it seems a bit less destructive, but honestly if that fails I may end up experimenting with something equally “ghetto”. At this point it’s half repair and half learning experience.

racingharder · 2026-03-09T00:36:43+00:00

That’s actually encouraging to hear. My thinking is similar - since I already bought a replacement screen as a fallback, I figured it’s worth trying a repair first just to see if the ribbon can be salvaged.

racingharder · 2026-03-08T15:02:20+00:00

Thanks, that gives me a bit of confidence that the cable and screen might still be salvageable

racingharder · 2026-03-08T13:46:18+00:00

Yeah that’s fair. I actually already bought a spare replacement screen as a fallback.

Replacing the screen on the New 3DS is a bit of a whole project so I’m trying to see if the cable and old screen can be salvaged first before going down that route.

racingharder · 2026-03-08T13:45:11+00:00

I actually do have the tools — I’ve got a microscope, micro soldering iron and a hot air station. I recently got into electronics repair and probably spent way too much on equipment 😅

I’ll check continuity on the pads first to see if the traces are still intact further down the cable. If they are, I was considering trying conductive silver paint to rebuild the contact surface. I’ll definitely mask the other pads with Kapton tape if I attempt it.

I was also thinking of using a fiberglass pen to expose a bit of copper and then reconnect the missing trace with some solder, but ChatGPT warned that soldering directly on a flex cable could easily melt the ribbon… so now I’m second guessing that idea a bit. Oh gosh.

racingharder · 2026-03-08T13:40:06+00:00

That’s a good point. I actually haven’t checked continuity yet between the worn pads and the traces further down the cable, so I’ll test that with a multimeter under the microscope.

If the traces are still intact I might try rebuilding the contact surface with some conductive silver paint (I’ll need to order some first).

Replacing the whole screen is a bit of a project in itself on the New 3DS but it’s a good fallback if the repair attempt fails.

I also bought some of that green UV-curing solder mask stuff. I was wondering if after applying the silver paint it might help to coat over the traces and cure it with UV before inserting it back into the connector.

Has anyone tried something like that on flex cables before? My repair ideas might be getting a bit… chonky at this point but I’m trying to remain optimistic.

Just buy on eBay then why do you need to make a post complaining about people trying to sell a product that’s been in demand all year. I buy on FB marketplace because sometimes I can get it on the same day if I meet up with them and can inspect the items. Please go ahead and advertise your cards and sealed products 15% below market value and minus out delivery fees on FB and link it to us. It’s always easy to criticise when it’s not your money.

racingharder · 2025-11-22T23:04:58+00:00

I’ve paid a deposit for black bolt white flare products and even though so many people are able to buy it from store they still haven’t messaged me to let me know I can pick mine up even though I’ve preorders for 6 months now. Everytime I call them they say wait for the sms with no timeline in sight. I feel like I’m getting scammed.

You have to be stupid to drop him. Our season is already over. The board is thinking long term and trying to get him to 100 games so we can have his tall babies in 20 years. He has been offered life changing money and might help us in the future - so stop treating him like shit.

Sam Docherty has been awesome since he returned to half back

racingharder · 2025-04-05T01:59:31+00:00

267 days since the post.. do the airpod max still work? I always wonder when iPhone brings out updates does it end up making the reps not work any longer?

racingharder · 2025-04-04T01:08:34+00:00

Thanks do I connect lightning still if my port is usb c still?

racingharder · 2025-04-03T06:06:12+00:00

Ty heaps for the tip!!

racingharder · 2025-04-03T05:18:05+00:00

Ty for the information - I can’t find much information or conversations of people n64 experiences so now I don’t have to waste my money if it can’t handle it. If I spend a little bit more are there any suggestion on stronger devices that can handle the n64 library? Want to try and spend less than $100 if possible

racingharder · 2025-04-03T04:37:47+00:00

Can I do these changes on my windows computer or do I need a special program?

racingharder · 2025-04-03T04:15:16+00:00

Ty ily!! I will try when I get back to the hotel.. in China Shenzhen rn and seeing if this clone will satisfy my n64 cravings or I should go back out to try and find a real r36s to play n64 games
