how long does it take repairs?

my gamepad screen one night glitched, and became unresponsive to touch! not broken, not frozen, not scratched, not dirty! it should be reaching nintendo tomorrow, but i'm just wondering if nintendo can quickly repair it! oh, also the only buttons that work, are the bumpers, and the X button. the rest are completely unresponsive! thank you for your help!
