3DS turns off randomly

[Raygron]

My 3ds capture card was working fine until yesterday. The problem is that it will only turn on when it is charging and it will automatically turn off after being on for a minute or so making a pop sound sometimes. Any solutions? I hope this is only a battery problem.

Did you drop it? Bang into it? Those are similar symptoms when that happens and the cables get somehow slightly knocked out just enough. I've taken them apart and put them back together and that same thing happens and it fixes itself when I reseat the flex cables. The turning off and pop sound is happening when the 3ds detects something is wrong such as the flex cables not properly connected and and it shuts itself off to prevent further damage. A light drop can do that.

Also sounds like it could be a bad battery.
