If the Nintendo 2DS’s top screen does not light up when the device’s power is switched “on”, the display or motherboard might be faulty.
You must determine if the screen remains black due to a problem with the display. Make sure that the “power on” LED on the side of the console is lit up, to signify that the screen should indeed be on. If the LED is on, and the screen is blank, the display itself may be broken. Follow this guide to replace the display screen.
You must determine if the screen remains black due to a problem with the motherboard. Make sure that the “power on” LED on the side of the console is lit up, to signify that the screen should indeed be on. If the LED is on, and the screen is blank, the screen’s connection to the motherboard may be faulty. Follow this guide to access and replace the motherboard.
If the Nintendo 2DS’s lower touchscreen does not respond to touch from fingers, the touchscreen or motherboard might be broken.
You must determine if the touchscreen is unresponsive due to a problem with the touchscreen itself. If the touch screen is displaying imagery as expected, but using an object that is expected to trigger a response from the screen, such as a finger or a touchscreen stylus, does not cause a response, follow this guide to replace the touchscreen.
You must determine if the touchscreen is unresponsive due to a problem with the motherboard. If the touch screen does not turn on at all, even when the power on LED is lit, then the connection to the motherboard may be faulty. Follow this guide to access and replace the motherboard.
If the Nintendo 2DS’s trigger buttons (the “L” and “R” buttons on the upper left and right of the console) are stuck in the pressed position, there might be matter underneath the buttons or faulty springs.
If either trigger button is stuck or unresponsive, there may be something underneath them preventing them from activating correctly. Follow this guide to access the buttons and look for anything that does not belong. Remove anything that might be blocking the buttons.
If the L or R trigger button is stuck or unresponsive, the springs that hold the buttons in the standby ‘up’ position may be damaged or missing. Follow this guide to access the buttons, and look for a small spring underneath each. If there is no spring, or it is inoperable, it must be replaced.
If switching the Nintendo 2DS’s power ‘on’ does not cause the device to be powered on, the battery or power connection might be faulty.
The device may fail to power on due to a faulty battery. First, ensure that the device is charged and the power switch is in the ‘on’ position. If these actions do not cause the ‘device on LED’ to light up, the battery may be faulty. Follow this guide to remove the battery. Test the battery with a voltmeter; if there is no voltage, the battery is dead and must be replaced.
The device may fail to power on due to a faulty power connection. First ensure the battery is not dead, the device is charged, and the power switch is set to the ‘on’ position. If these actions do not cause the ‘device on LED’ to light up, then the power connection may be faulty. Follow the trigger button replacement guide to remove the back panel to access the main internal power cable. If the cable is not plugged in, it will have to be replaced.
The device may also fail to fully power on, with the blue LED flashing on then off quickly, within 1 or 2 seconds. Try removing the SD card and see if the console boots correctly. If it does, it might be that the contacts to the SD card are dirty, on the SD card or on the reader, that the SD to micro SD card adapter is not secured (if you are using one), or that the filesystem on the SD card is corrupted. Plugging the SD card into a computer should show whether any filesystem problems exist, and usually offer you to fix them, depending on the OS.
If the Nintendo 2DS’s charging port does not grip the charging cable tightly, the cable or charging port could either fail to charge the device or cause damage to it.
The cable may be why the charging cable and charging port aren’t interfacing properly. If the 2DS’s charging port does not properly hold the charging cable, first check the head of the cable. If the metal contacts on the head are loose or covered with any sort of grime, attempt to tighten them or clean them, as appropriate.
The port may be why the cable and port aren’t interfacing properly. If the cable is in working order, but the Nintendo 2DS still won’t charge, follow this guide to access the charging port internally. It must be replaced.
