    Hi all,

    I have been spending my lock-down months trying to fix some old consoles and handhelds for fun and have found the New 2DS XL to be a nice console to work on, and have managed to get a few of them up and running again now.

    However, I have two consoles that are not happy for seemingly the same reasons, so I am hoping there is someone out here with a bit more knowledge that might be able to make some suggestions.

    Console 1)
    This was bought with already having the "popping fault" where the blue light comes on for a few seconds, and then goes off with a pop from the speakers. Opening it up, the tops screen ribbon was in bad shape, so I got that swapped out, but it did not fix it. On closer inspection, the bottom screen back light connector had been "opened" at some point so was not making a good connection. Holding it in place I was able to get it to boot. Given that the I was unable to keep it in place, I thought I would try reinforcing the connector with a little solder. During this, I had clearly managed to bridge across the pins, it still booted but there was no backlight. I managed to unbridge the connections, but annoyingly I still couldn't seem to get a good connection, and now holding it down didn't allow it to boot. This is, I think the point where it stopped working. Since this point, I have removed the connector completely, soldered a screen on, re-bridged the pins, fitted a replacement socket and connected it to a different backlight. None of these made any difference. I can only assume at this point that something has failed such as a capacitor or fuse.

    Console 2)
    This motherboard had a slight bend on it near the battery side, and with both the backlight and NFC connectors completely missing. Given that I already had some of these connectors for console 1, I went ahead and fitted new connectors and hooked it back up. I gave it a test while still opened up, and it turned on. I still hadn't put all the screws back in, so wile testing it out I had a few cases of it turning off. So, I started screwing it all together properly so everything was on apart from the back casing which was connected but not clipped in. Still working. I then tried to fit the back case on, while it was on. (urgh) and it didn't seem to want to go on. I was carefully trying to get it all lined up when it turned off again. So I took the back cover off again, checked all the connections and still nothing. Since that point it has failed to boot each time.

    So that is where we are, 2 consoles, both that had issues around the backlight connector that now wont boot even though all things are connected.

    I have another console arriving soon that is supposed to just have a broken top screen (cracked, so still electrically sound), so my next step is probably to start comparing readings between all 3 boards to see if anything shows up.

    If anyone has any suggestions that would be great! But if not, I will update this thread with anything I do find out in the hope that others may be able to fix this issue too.

    Sorry that nobody posted anything in response for all of these months. If you ended up doing any work on this further and got results, I would love to see it. I'm working on a similar problem with a 2DS (original bread slice, not XL) and since I've seen this on other 3DS models, I suspect there is overlap between the different variants. If you have any insights, I'd be welcome to read them.
