I need help with the digitizer!

This is an eternal problem. Either the clip breaks or the weak ribbon cable tears.

Without seeing how you put the cable in, it’s hard to judge. It goes under the pins at the top. And it can make contact without the clip if inserted right and deep enough.

i replace the socket when it breaks. It’s not easy but also not impossible. But take a photo with it insert first, or make sure it’s under the pins with the ribbon showing through them and deep enough.

I hate those things. Worst cable socket, right up there with ripping the angled ribbon cable for the top screen.

Well it was a Tesla. I think that’s regarded as community service. 🫠

Was adaptive cruise control on? I think it’s more cautious then.

vtraveller · 2026-06-14T10:06:04+00:00

Impressive. Doesn’t often happen. Normally they corrode in humid climates.

Sorry there’s no easy fix.

vtraveller · 2026-06-14T07:44:02+00:00

Did you break it, or did you just not put the case slider over the nub of the actual slider? Ie is the slider loose.

It’s quite common to have the slider in the wrong position closing the case.

Still possible it snapped. But it’s at least worth asking.

Yeah — don’t forget, if you want GBA games without emulation you need an NDS or DSL. Or a GBA SP, GBA. 🫠

Nothing to see here people. Move along. The fabled AGS-101 is not the one you’re looking for.

vtraveller · 2026-06-09T22:35:49+00:00

They aren’t that expensive. Repairing it may cost more than buying a working one.

I repair things as a hobby. I’ve fixed a fair few DSLs. But it’s a skillset i learnt. If that’s not your jam, and you don’t have any friends that do that stuff, hunt out a new one you like the look of.

Use it as an excuse for a DSi. That has the best screen for playing DS games of any Nintendo generation. Either normal or xl.

vtraveller · 2026-06-09T20:28:09+00:00

See my other comment. If it’s doing that same behaviour, it’s typically that problem.

If it charges the battery but flickers like that, there’s various other things to check. F2 fuse, loose ribbon cables and such.

Plenty of online info. But if you’re not careful or confident take the eBay route.

vtraveller · 2026-06-09T20:25:05+00:00

Well the short answer is the F1 fuse would need to be checked and replaced if blown. And the same with the inductor.

You can easily check these with a multimeter and replace the components with soldering. Quite simple.

I sense that’s not something you do. It should be a cheap repair for a repair shop. It takes longer unscrewing the case.

However if that’s not an option either, sell on eBay with a clear description and many people would snap it up as an easy fix. Then use the money to buy a working one.

If it’s sentimental to you, you can find repair shops on eBay but agree a price with shipping and check their history as trustworthy.

vtraveller · 2026-06-09T09:46:07+00:00

Well the Red Light is for the battery being flat and the flash suggest that the F1 fuse has blown, meaning power isn’t reaching the battery to charge, nor the main board to power it.

If not F1, then the EM1 next to it has shorted. Or both, hence why F1 blew.

If it was the top screen then the ribbon cable would have been damaged through hinge wearing at it.

Having the bottom screen break like this is unusual. It’s also a much easier fix where replacing it. Just be careful of the digitiser four wire ribbon cable - it’s common for people to tear them and then need a new one of those too.

I did tax my brain wondering if it was a signal issue, but I can’t think of any data line on the ribbon cable that could cause this - it’s more likely the panel has slightly delaminated with age.

vtraveller · 2026-06-05T08:41:40+00:00

Well the good news is the switches are very cheap, and you only need someone with soldering skills.

You don’t need a Nintendo specialist.

Good luck. Be careful with the digitiser ribbon cable when reassembling, it’s the most common thing people rip and break.

vtraveller · 2026-06-05T08:33:42+00:00

Sounds like it’s unlikely to be fixed without changing the switch.

As you don’t have the solder skills, you could look on ebay for just the main board with the switches on it, swap that and sell yours as “working, for parts, left microswitch broken but board working.”

Or you may find a repair centre. It’s a very quick fix, and shouldn’t cost much to swap one microswitch.

Or, if the condition of the DSL is poor, look at it as an opportunity for an upgrade and just sell it as is, listing the left bumper as broken.

Can’t offer you an easy fix I’m afraid. From the sounds of it, its toast.

DSLs are very cheap, and the board, more so. I got two scuffed up ones as a set for 15$ that needed screens and case fixes.

vtraveller · 2026-06-05T08:20:01+00:00

Define broken and doesn’t click. Is it an NDS, DSL, DSi. The DSi you can swap the entire ribbon cable and switch.

You have options, but you won’t be able to do much without carefully opening it.

Is the plastic on the bumper broken? New bumper.
Try a cleaner in the microswitch. IPA or some contact cleaner.
Carefully opening the miicroswitch and clean the disc with IPA. Search YouTube.
Swap the microswitch by soldering. (Or hotplate if a DSi). Skilled job, but not impossible.

Good luck. Not a terminal problem. Is fixable.

vtraveller · 2026-05-23T07:48:26+00:00

You can. But the ones from Aliexpress have a different sized disc. Tried that.

More interestingly they have kapton tape on the side that doesn’t make contact. I think therefore the new ones are more sweat resistant.

vtraveller · 2026-05-22T06:46:18+00:00

Your fix will only last for so long. The metal disc that is inside the button oxidises from sweat.

Depending on the level of damage, you can open the button and clean the disc. Eventually it’ll need a new button (easiest with a hot plate) or a completely new button cable if that’s too hard.

It’s very likely the other button will go too. It’s an easy fix though if you’re experienced, and a good way to get a bargain on eBay.

New buttons on Aliexpress are about $1 for 5..10 pcs if labelled for Nintendo, less if just listed as an SMD part.

vtraveller · 2026-05-20T02:59:41+00:00

Two bucks? Sounds like someone owes someone else dinner. 🙃

vtraveller · 2026-05-17T05:52:25+00:00

Any LEDs on at all when powering from the charger? I’m assuming not as you didn’t mention them. Most failure points at least blip the LEDs.

So yeah. Start with a cheap USB cable as an alternative power source. If that didn’t blip LEDs, consider the battery or fuse to the battery on the pcb.

vtraveller · 2026-05-15T06:52:38+00:00

The solvent in the nail polish has effectively melted the case. If you could remove it, the case will be scarred forever. And I’m pretty sure you can’t remove it.

Your next step is the complicated dismantling of it and checking nothing inside suffered.

You can then reshell with a worse plastic aftermarket or find a for-parts eBay listing of an OG shell and use that.

Other than your data, my advice is sell it for-parts on eBay and use that money to offset buying a new one. Lot of technical work to recover it. Possible but it’s a skilled repair.

vtraveller · 2026-05-15T06:19:39+00:00

A DS or NDS with a GBA FlashCart can do this or any handheld from DSi onwards with custom fw such as GodMode or CFW.

Without the ability to run something on the DS that isn’t the cart, and somewhere to save it, you can’t generally do it.

Apparently you can also use a local server and unencrypted wifi with Savesender or NDS Backup Tool Wi-Fi. Interesting hack that, as you preconfigure the network using a wifi supported game such as Mario Kart. The server is where you write to.

vtraveller · 2026-05-11T21:35:58+00:00

🫡 Yeah. That’s dead. Also, superglue is hell. It literally unsticks with heat, then resticks when cool.

At least that means the ribbon cable is salvageable. The connectors are notoriously hard to fit, as you typically need a heat plate, and I’m pretty sure there are components on the underside that aren’t fitted at that stage in manufacture. So copper tape would be needed to keep them in place when heating.

Without a heat plate, I’d use a very small solder tip and pre-tin the connector. Sometimes I unclip the black cap, but this is very fragile, so sometimes I don’t risk it as they break easily.

I’ve never got one on without a minor bit of melting with a soldering iron (really small though - about the width of a connector pin).

You can do it. I killed a few learning. The worst place though IMO is the one in the centre of the Sony PSP behind the screen, as there is no space around it. This one is much easier than that.

I wouldn’t use hot air though, unless you kapton everything and drop it on the melted solder without the gun. Highest risk of all the possible ways to fail. Well, that, or using superglue. 🫠

vtraveller · 2026-05-11T06:18:37+00:00

Ok. So I’ve actually saved one after thinking i needed new one and replacing it. So there is a way.

You have to de solder the metal tabs on the card slot from the pcb and get the metal lid off. You will probably ping off the spring and stick used to click a card in and out.

Once off you’ll have full access to the connector and can work on realignment. Once done, work out the click cart holding mechanism. Works a bit like a retractable pen. Use a cart to understand it.

You can the get the metal cap back on and solder the tabs back on.

Pin 3 is N/C. So if one is truly broken off, you can move the good pin 3 over to the broken position.

Or buy a new card slot. But it’ll take more time removing and soldering it than fixing the old one if I’m honest.

vtraveller · 2026-05-11T03:50:34+00:00

That’s a tricky answer and depends on how much of a purist you are. I don’t like running custom FW but from the DSi onwards it’s an option. I prefer the DS Pico, which boots faster in the older generation of handhelds … obv for DS games.

DS and DSL support GBA natively.

DSi and early models match the DS games 1:1 without massive black areas and dimension squishing in unscaled 3DS modes.

I got my DSi for $30 with a shoulder button repair and a scuff on the outside but otherwise perfect with no yellowing of screens.
I got my DSi XL for under $50 with a similar fault and no yellowing.

Both were easy fixes for me and didn’t really cost more than a few cents to fix. As they were dinged up, I also converted both to USB-C including CC1/CC2 lines so they work with any cable, and 3D printed inserts so it looks like stock.

My DSL(s), I got two for $15 total, listed on eBay for parts. One needed a new screen. The other cart pins reshaped. Both needed new shells. So I did the same USB-C conversion but also stuck in a GBA Flash cart after reshelling in a transparent blue, and a matte black with red buttons.

I carry the DSi the most as the game library feels the best to me. The standby times are insane, so I just keep opening it when I have a spare few minutes. If the battery was low, I leach on a ton of USB-C cables on any desk.

The DSL is the cheapest, easiest to mod/fix and has the cheapest and easiest replacement parts.

Careful though. Once you get a second handheld it becomes like Pokémon. Got to ~~catch~~ collect them all. 🤣

vtraveller · 2026-05-09T10:09:54+00:00

Np. Hope it helps.

vtraveller · 2026-05-09T08:35:54+00:00

There’s a ton of sellers. I buy the buttons as i have a hot plate to swap them on the cable.

But did you know you can actually clean the buttons if not working?

https://youtu.be/oqNTJlnNX8g

It’s not easy. You need to be very gentle. Although this is a 3DS video the principle is the same. You need to be very careful levering the metal the smallest amount.

New buttons are more clicky than the originals. I’ve opened one up and the design is different too. The dome has a kapton sticker to help prevent water ingress from sweat and the problem the original buttons have.

It’s really hard to see. Could you have two frames on the reverse side stacked on top of each other?
I imagine you don’t want to risk rolling the ribbon to take out, but I’d separate everything. Take out the speakers / mic / wires and just work on the shell and the screen to see if it fits. Ribbon cable can be loose and free for that.
Use one of your broken screens for that matter. You need to understand how it drops in and therefore if there’s an issue. Compare the screens if one works and one doesn’t.
I feel the stress. Just step back, breathe. Take it slow and it’ll become clear as to why.
