    Just repaired a faulty DS lite which had a broken power switch. The unit powers on fine, but when I slide the switch up to turn it off, nothing happens!!

    Any ideas on this one?

    Is there a button combo you can use to shut down the ds?

    If you have moonshell you can shut down using it.
    it doesnt really make sense that it wont turn off using the power switch. If I had a schem of the ds I could tell you whats wrong.

    Maybe the switch is broken, or one of the contacts isn't soldered well

    Ive soldered a few power switches before.. I've checked this one out with a continuity meter and the soldering looks fine.. If it was a problem with that I'm sure it wouldn't turn on either..

    10 times out of 10 it turns on no problems, and 0 time out of 10 it turns off.

    Yeah I'd love a DS schematic.. Anyone know if such a thing is available?

    This thread is a little old... But you are justified in bumping/digging it up I guess, if your DS really is broken in the same manner. Good luck fixing it!

    Hardware solutions:
    The DSL switch is prone to breaking in this manner (on, but not off). Replacement can be found in many shops, e.g. here: http://www.console-spares.co.uk/catalog/gb...how/NDSLPS.html (including instructions)

    In schematics, the power switch is labeled "SW13" : http://i25.tinypic.com/i4fhn5.jpg - pin 2, 3, and 4 are common GND and pin 1 is high (on some boards pin 3 is not connected).

    A photoreport of some guy who did a succesfull repair of a DSL: http://www.flickr.com/photos/shalf/tags/nintendods/

    Software solutions:
    You can use the shutdownfeatures of your flashcard-system (e.g. AceKard/AKAIO);

    ÂÂÂÂPA_Shutdown();

    }A precompiled version to put on your flashcard is included in the above ZIP file.

    I have this same problem, I did change the power switch with a new one. I still get the same problem. I'm thinking it's a fuse. Has anyone found the problem?
