All noise and no screen

Hi I bought a wii u LCD screen for my sons Wii U to replace the old one as his screen had cracks on the inside. I followed exactly the instructions but the screen stays black i can hear all the noises when i touch anything. It lights up as if charging with the red light but it only stays on for about 1 minute then goes off. Any ideads hiw to fix ive done it 3 times now and im confident everything went back where it should. I bought the screen from amazon.
