My L button is always active. No liquid was spilled over it , it didn't fall downwardly and I didn't press the button as well hard. I too never opened it or modified it in any way. Plus, there are no visible signs of whatever issues, the button is not sticky or anything. At that place where never whatever problems with the push before. If anything, the feedback from information technology seems a petty weaker than the feedback from the R button, but I think it was like that from the beginning. I also still have warranty. I was playing Luigi'southward Mansion when suddenly the button wouldn't go off again and it just stayed that mode since then.

So... that seems similar somewhat of a common issue, the Nintendo Tech forums (and other places) are total of people with the same or like problems. Ane guy in that location writes:

Software problem? :/ If there'due south really a possibility that information technology could exist a software problem, I could but update to 9.2.0 and see if it does annihilation, only I'grand doubting the use of that at present.

Anyways, you lot might suggest now that I just ship it in to Nintendo for repair. But that's a N3DS on 9.0.0, and I don't desire some idiot at Nintendo to update it or even worse, replace it with a new i > FW 9.2.0. Add to that that having to uninstall all my legit CIAs and somehow backing up the saves will be bloody annoying likewise.

Sooo... any ideas?

BS that information technology's a software trouble, or else more people would experience it. It's definitely a hardware issue, about likely something is stuck, similar the jump, and isn't allowing the push to return back to its default position.

The button does spring back. Just with a fiddling less forcefulness than the R button. Equally I said, I recall it was like that from the starting time.

The push button does spring back. Just with a footling less force than the R push button. Every bit I said, I think it was like that from the outset.

The way the push works though, is there'south a minor rod on the opposite side of the button, and when you press on the button, it pushes the rod and it pushes on a pocket-sized contact that completes a circuit, which is understood past the system to be the L button. That'south probably what's stuck.

Have you taken a look inside your 3DS. If you aren't afraid and are very careful, you might be able to find the trouble if you open the 3DS. One thing to note is that if yous can't get the screws out, don't go along trying or else yous'll most likely strip the screw. If you strip the screw you're going to take a very bad day.

If you rather not affect anything, then I guess your only option is to send it in for repair. If it's nether warranty they'll encompass you.

I experienced the aforementioned trouble but with the DPAD, I opened information technology, removed the tiny stiker under the argent buttons and removed a black point caused by shock, information technology'southward and then tiny that you'll need a needle... and the problem however happened.

In the sdoulder buttons should exist the same, and check that the ribbons are correctly atached on their ports.

In order to non mess with something with wrong procedures or harmfull deportment (break apart the ribbons) see this guide here:

Merely as I said, the problem is a random ocurence, it only happens some times, mine didn't get solved by cleaning, later some days, it only was gone by itself all of a sudden... wasted money on another 3DS just to replace my old i, but on the brilliant side, I now have two 3DS, 1 to play and test so many things (hardmoded) and another justo to play gaems LEL.

CONCLUSION: Information technology'due south unknown if it is a Software problem or Hardware, and if the 2nd, cleaning the area or replacing does nothing, you just need to have patience and await for it to become normal after some fourth dimension.

go into a ds game, if its still stuck then definitely a hardware issue. the hid code is completely different for twl firm.

pretty certain it'due south hardware anyway.

Okay, cheers all!

The way the push works though, is there'due south a pocket-sized rod on the opposite side of the push, and when you press on the button, it pushes the rod and it pushes on a small contact that completes a excursion, which is understood past the arrangement to exist the L button. That's probably what's stuck.

Have you taken a look inside your 3DS. If you aren't agape and are very conscientious, you might exist able to discover the trouble if y'all open upwardly the 3DS.

If you rather not touch anything, so I judge your merely option is to send information technology in for repair. If it'southward nether warranty they'll encompass you.

I experienced the same problem only with the DPAD, I opened information technology, removed the tiny stiker under the silver buttons and removed a blackness betoken caused by shock, it's then tiny that you'll need a needle... and the problem nonetheless happened.

In the sdoulder buttons should be the same, and check that the ribbons are correctly atached on their ports.

The problem with taking it apart is, I might not be successful, and so I will have a broken L push plus no warranty anymore. The trouble with sending it in is, I expect ane of ii things to happen.... they first update information technology to ix.9.0 in an attempt to "prepare information technology", or (if the repair is expensive) I go a new one, which won't have a good FW version. N3DS's on good FW versions have become somewhat rare, so I don't want to mess that up either. Stuck between a rock and a hard place, I guess :/.

Can y'all think of whatsoever way to go it unstuck without opening it? Waiting is an option, of course, but I'd rather do something to become it fixed. I also read somewhere else that a toothbrush might help, so I'll try that later.

go into a ds game, if its withal stuck then definitely a hardware issue. the hid code is completely different for twl firm.

pretty certain it's hardware anyway.

Expert point! I don't take any DS games lying around, merely I'm pretty certain I can infringe one this afternoon.

The wise option here is to just send it in a be patient, you'll get your 3DS back in better status then when y'all had it before and your problem will be gone. If you lot choose to open up it, you're warranty will be voided (however I don't call back they'll know if you put everything back together like it was before) and y'all may even pause your 3DS if you don't know what you're doing.

become into a ds game, if its still stuck and so definitely a hardware effect. the hid code is completely unlike for twl business firm.

Yeah information technology happens besides, in my case launching DS style all the same had the button trouble, so I know information technology's the hardware the wrong part. But srsly, the problem gets fixed by itself after sometime, cleaned a lot of times and as well I was certain that none of the hardmod wires or any pin was making a short.

Yeah, the main problem with sending it in is that I am almost sure I will get an updated 3DS dorsum. I'1000 as well using it as development arrangement, and for that utilize case, a system update effectively ways a brick (and not ameliorate condition ).

Yes it happens too, in my case launching DS fashion notwithstanding had the push problem, then I know it's the hardware the incorrect part. But srsly, the problem gets stock-still by itself afterwards sometime, cleaned a lot of times and too I was sure that none of the hardmod wires or whatever pin was making a short.

Certain, I won't blitz things. It's just annoying as hell. Tomorrow I have a long trip and I hoped that I could laissez passer some time with the 3DS. I'm also sure that there is no 'difficult' crusade to this problem.

Blow hard into the side of the button. The verbal same problem used to be pretty mutual with the DSi and that fixes it.

• #13

get some compressed air in it.

become some compressed air in it.

Already tried bravado into the side of the of the button. Also the affair with the toothbrush. Didn't help, though. Adjacent up is getting a can of compressed air, but I have my doubts wether this helps.

I have also observed that all the other shoulder buttons (R, ZR, ZL) brand a loud clicking sound, while the clicking audio from the L button is somehow 'muffled'. I doubt that this could be a software issue. If I could better sympathize how the L button works, I might come up with a solution. Any chance in that location'southward a adept picture of that somewhere?

• #fifteen

Whatever hazard in that location's a practiced movie of that somewhere?

The circuit of the buttons will vary between 3DS models, but they all work pretty much the aforementioned:

The plastic office that you printing has a tiny little nub inside which will press the black push button on the circuit. When I say 'tiny' I hateful extremely small (nearly 1mm in width). There's a lot of room for errors if you driblet your 3DS, become stuff stuck in the button, or put too much strain on the button. I dropped my New 3DS Twoscore and now the shoulder R should button didn't annals sometimes. I fixed this by putting tape betwixt the plastic function of the shoulder button and the main 3DS torso, but I doubt that'll solve your issue. It'southward hard to say what's the crusade of your issue unless y'all take a look at information technology yourself.

• #16

Give thanks yous! The black push in that excursion is also resposnible for the clicking audio, right?

On the matter of sending it in I establish this:

2) Generally when you send in a organization for "repair", you become a new refurbished panel back.

Sounds plausible. And, and then much about getting the same FW version back. Now, a used 9.0.0 N3DS, even with an unresponsive L button, is worth more more than a make new >9.2.0 N3DS at least where I alive, so I gauge sending it in is out of the question now. Still hoping that I won't have to open it, though.

• #17

Thank you! The black button in that circuit is likewise resposnible for the clicking sound, correct?

Yes the black button is what makes the button "click".

• #18

Okay, some new info (after I at present understand how these buttons work).

• The feedback from the L button is normal, but the click sound is missing (I merely hear the button snapping back).
• If I slowly tilt the N3DS and put my ear onto the L button, it sounds like a small part is moving around in there.

Judging from the two points above, it sounds like the tiny nub (that's designed to push button the tiny button inside) bankrupt from the 50 push. Can't exist the reason, though, cause then the L button would be unpressed all the time. I guess the tiny button inside somehow got stuck then. No thought most the small-scale moving part though - that may exist perfectly okay.

Likewise, with how things are with warranty repairs, I guess I don't have any option merely to open it. I'll get professional help, though. More later, but if you've nonetheless got any ideas, everything you could add together is profoundly appreciated.

Besides, with how things are with warranty repairs, I guess I don't have any choice just to open it. I'll become professional help, though. More than after, but if you lot've withal got any ideas, everything y'all could add is greatly appreciated.

Use superlative notch screwdrivers, don't become for the inexpensive packs. The screws on the 3DS are very tight, it is very easy to strip them if you are non careful or are impatient. If you practice stop upward stripping the screw even the slightest, yous probably should cease. If you attempt to forcefulness it, you'll end up stripping the screw completely and you'll have to drill a hole to destroy the screw (very dangerous and will void your warranty guaranteed). Seeking professional will make it less likely you lot'll screw up your 3DS.

A Nintendo representative told me there is some kind of special seal that gets cleaved when yous open upward your 3DS, simply I think that's a bunch of BS afterward I have looked inside myself.

Judging from the two points in a higher place, it sounds like the tiny nub (that'south designed to push the tiny button inside) broke from the L button. Can't be the reason, though, cause so the Fifty button would exist unpressed all the time. I guess the tiny push button within somehow got stuck then. No thought about the small moving part though - that may be perfectly okay.

I don't have an N3DS, but the shoulder buttons on the N3DSXL are more or less the same as on the old 3DS. On the old 3DS they can become stuck if the connector is not seated properly or if, as you described, the piffling nub is stuck. On old 3DS consoles either issue tin usually be fixed by cleaning the button (or connector if necessary) with a toothbrush and a flake of isopropyl alcohol. Although I haven't yet come across an N3DS with this problem, I'm sure the solution is more or less the same.

I'g not sure if the N3DS is the aforementioned as the Forty, merely opening the N3DSXL is slightly counter-intuitive since you must begin lifting the back part of the housing off starting from the rear (the side where the shoulder buttons are) and then that you tin can detach the shoulder buttons from their connectors using a fingernail before lifting the back part of the housing off completely.

I would beginning try cleaning the shoulder button with a toothbrush and testing. If that doesn't aid you can try to actually pull the little nub out of the shoulder button to clean beneath, only this is a bit risky since you could damage it while prying it out. Though the ribbon cables are different, the buttons themselves look to be exactly the same every bit the old 3DS, so I suppose if the little safety nub were to get damaged you lot could perchance have one from the shoulder button of an o3DS.
