    Well, a friend of mine has a o3ds that sometimes, turns off by itself when you open it from standby mode, doing a "plop" sould.

    Any idea of what could be done? Thx in advance

    There might be some damaged cables in the hinges. This is something the dsi did if the components in the hinge got damaged.

    If I remember correctly, it's a loose ribbon cable. I can't remember which exactly but I think it's the camera cable?

    Just be careful not to damage anything when you open the 3DS. I ruined my DSi when I opened it because I wasn't gentle enough with the ribbon cables.

    In both of your cases @MAXLEMPIRA and @Arubaro it sounds like the upper LCD ribbon cable is either loose or damaged. To be specific, it's not the LCD losing contact itself that is the issue, it's the speaker ribbon that plugs into the top LCD. The speakers are one of the few things that need to be connected for the 3DS to work - it could work without the top screen, wifi antenna and camera, provided that you managed to connect the speakers directly without using the ribbon cable that plugs in the top screen.

    Mmm :/ and the ribbon should be changed with the screen, right?? The sound and the image (2D/3D) works perfect

    No, it's just loose, not broken.

    Reseat it and make sure it is all the way in.
    You don't know that. It could have gotten pinched in such a way that it has started tearing slightly so when the hinge is put in a specific position it will sometimes shut off. It shouldn't happen to a console that has never been disassembled, but nothing is perfect.

    Does that relate to a delay in possible startup? Like if you turn on the system and the screens are both black and you hear the sound of the menu then it forces itself to shift on? But the action is enough of a delay to notice.
    I have been wondering about the hidges since the system has done line random showup (literally random - no rhym or predictability) on my system and it had the hidge squeak when I first obtained (though that disappeared). Not seen on DS games though. Really need to check 3DS titles again.

    The popping-and-shutting-off problem occurs if either backlight is disconnected. If the system doesn't boot at all, then yes, as others have said there are several possibilities: 1) the lower screen backlight cable is loose or damaged 2) the upper screen backlight cable is loose or damaged (the tiny one in the top of the housing) or 3) the speaker cable is loose or damaged (connector p7 on the motherboard)

    However, if, as in your case, the system does boot and the issue occurs mainly when you open the console up from the closed position, the speaker ribbon cable is actually torn, not just loose. There will be a tear in it that just barely breaks one of the conductors on the outermost edge of the ribbon cable. When the console is fully opened the tiny tear is stressed and the connection is fully broken, causing the system to shut off. When the console is closed or opened gently it may work for a time because the tear is not being stressed and the connection would still be complete, but only tenuously. The problem will get worse over time though. If you open the system up the tear will be large enough to see easily if you remove the speaker cable and lay it out flat. Whenever I get these consoles for repair and look at the speaker cable I'm always astonished they work at all with such severe tears in them.

    As The Real Jdbye said though, it's not your LCD. The LCD wouldn't cause the system to shut off. If the upper LCD ribbon cable were bad the system would still boot, but you simply wouldn't see anything on the top screen. It wouldn't be the lower screen backlight cable either since that one is located in such a way that it would never become damaged via ordinary use.

    tl;dr version is: replace the speaker cable. It's likely torn.

    Thank you for your detailed analysis, Smile Citrus. Just side question, the cables which traverse through the hidges, have you ever found them to be tangling together or interfering to cause line distortions on the top screen? Could it also affect the speaker cable in the long run?

    Sorry for the late reply. I didn't see your message until now.

    No, I've never actually seen them become tangled on their own. All three cables are kind of rolled up into a barrel shape and forced through a small metal cylinder, so I don't think it would be possible for them to become tangled unless somebody had previously repaired the system and didn't feed them through the hinge properly when reassembling it. I don't know what would cause lines or distortions on the upper screen. I have seen that occasionally with screens that weren't cracked but in those situations I just replaced the screen without trying to figure out what was wrong originally. But I would try cleaning the connector and the tip of the ribbon cable with isopropyl alcohol just in case it's only a contact issue.
