If your Nintend DSi touch screen is not responsive, it may need to be calibrated. What happens if you can’t get to the menu to recalibrate it though? You might have to start the DSi at the calibration screen by using these steps:
1. Press and hold the L Button, R Button and Start.
2. Continue to hold these buttons while pressing Power.
3. Keep holding the L, R and Start buttons until the calibration screen appears.
4. Follow the on screen directions to calibrate.
