Hardware My 3DS died?

[Sliter]

well just updating again .. not sure if I have any hope here :v
I got a new screen and tried it , I'm still with the new speaker ribbon, but one of the cables get out the robbon, it need soldering... I tested the new screen anyway, now no *POC*(maybe because that one cable?) and now the botton screen flashes before turning off...

There's any hope for me?

Hmm, that's puzzling. I would have thought that replacing the speaker cable would fix the issue. I'm mostly speculating here at this point, but maybe it could still help you troubleshoot.

Typically three main things can cause the issue you're having: 1) bad speaker cable 2) bad or disconnected upper screen backlight or 3) damaged P7 connector on the motherboard

Since you replaced the speaker cable and the upper LCD it's probably not #1 or #2. However, you said that now one of the ribbon cables is disconnected. If that cable is the one for the upper screen backlight, then it could be the cause of the problem.

There are two small connectors on the speaker cable assembly. The lower one is for the upper screen backlight. It must be connected for the system to power on. If it's damaged or disconnected, the blue light will come on briefly, you'll hear that clicking or popping sound and the system will shut down. The same thing will happen if the little ribbon cable for the backlight is bad.



The system will still boot if the top connector is disconnected. It's for the parallax barrier. If it's damaged or disconnected the system will still work normally but the 3D effect won't work. So you can probably rule it out.

First, thank you so much for coming to the rescue!

The one thing that disconnected is actually the red wire from the speaker of this side in the photo, I expressed badly sorry ( and whats great? I think someone messed on the things here, the other speaker are totally out ... well triple soldering work here now :B)
anyway, when I tested the new screen it was already out, maybe this is why it didn't made the sound? Or this should work without the speakers there?
These two cables looked well conected, I don't think I inverted them or something.
Also the P7 don't visually look damaged on the board

So now what happens on the tries to turn on is > power led on for a time, lower screen flashes and then turn off

Oh, I'm sorry, I misunderstood. If it's just the red wire that came disconnected it's fine. The speaker won't produce any sound until you re-solder it, but the red wire being disconnected won't stop the system from booting.

I've got to admit though that I don't know what else could be causing the problem. Sadly, I'm pretty much out of ideas. The only other possibilities that I can think of are a bit unlikely, but it's possible that the replacement speaker cable you bought is also bad. Some of the third-party speaker cables are a bit thinner than the originals, so even when you lower the latch on the P7 connector they don't fully make contact with the pins. I once bought from a seller on Aliexpress a lot of 10 3DS speaker cables and 5 of them were bad, so I know for sure that some sellers don't test them before shipping. Sometimes you can get the console to boot for a brief time by pressing down on the P7 connector with your finger while you try to power the system on. If it works while you hold the connector and turns off when you stop pressing down on it, then the cable is probably bad.

The other possibility is that the P7 connector is damaged in some way that's not visible. Moisture can cause the pins inside to become corroded, which can cause these symptoms. But usually you can actually see the corrosion, so if it looks okay then the connector is probably fine. If you have some isopropyl alcohol though it might be worth trying to clean it using a toothbrush.

Sorry I can't be of more help. Good luck!

 

[Sliter]

well thanks for all this info! I'm still trying here ...
One thing is that the original cable(that comes in the console) don't look bad, I can't see any efect on the trails and even pressing the connector with the old or the new cables, nothing sifferent happened.
I don't have isopropyl alcohol but I used one "contact cleaner" product here , but no visible effect :B
I took some ohotos but i'm with a bit of dificult to get them here
The connector:

New ribbon:

Old Ribbon:

well I was playing and closed it, but it fellt on the floor :v I opened again and it gave the " removed cart" message , I turned off , but when I try to turn on again, only thepower light goes for a second, it makes an " poc" sound and the go off again ...
It's something possible to repair?it's an o3DS

Mine did this and I waited a few minutes and it worked again.

 

[mgrev]

well it all makes sense xD I'm able at least to open a DSlite and change hosing/replace top screen (did two actually), I'm just not good at soldering so I think I could give a it try ... I Will look for assebling/disasembling videos and try it them ... wish me luck :x

you probably won't need to solder anything. you hardly ever have to do. if you've replaced a ds screen this should be fairly easy

I waited like 2-3 days but it didn't revived :v then I started opening and stuffs :/ maybe I'm much unlucky lol

the problem is I wasn't sure it was the screen, the first I tried changing was the speaker cable

if u end up giving up, pls dont kill the mobo, as i am interested in buying the 3ds(if u just wanna get a new o3ds or something) or heck i'll but the mobo only!

--------------------- MERGED ---------------------------

btw this is old 3ds original size right?

hahah man, I can't "hurt" eletronics (at leats not propositally :v ), even if it not woking I can't destroy that xD well let see what happens here ... I really hope I can save that :x
(I know for much getting a new one is easy and chep, but it's not hete where I live lol)
Yep is an origional 3DS "lite" xD

the only time i hurt electronics whas when i had to nand mod my 3ds, my soldering iron tip was WAYYYY 2 thick so i managed to melt off2 microcomponents

wow D:
well this wasn't intentional XD I'm too bad at soldering , I can even trust myself to sold the speackers, even more a nand mod (and I wanted an controller mod here >w>)

and it was my first time inside a 3ds too lol

btw i'm going to make a gameboy macro soon too

If i open something to fix, it wont work anymore. Lesson learned for me and rip my 200€ laptop.
Sorry going lil off topic op, good luck.

it's very relative for me .. I worked with PC and printers ... and most of cases, if it's mine the chances of working is better ... x3x

and thanks .A.

oh yes .. but you need to open less to get to the nand, right?
macro? xD

i also removed the cartridge slot and broke that too i somehow was to scared to take the whole mobo out lol

keep in mind that this was a while ago, when the Palantine CFW was relevant, and i've done a lot more hardware since then.

I see xD wel messing in the hardwhare is a thing =3=

and not yet:/ if I can i wil post a photo of it alive here XD

also, the *POC* souund means there is a ribbon cable loose, i remeber when i got a new semi broken mobo for my 3ds i had to completely disasemble/reasemble the whole thing 6 times to get it to work
