История для "iPad 6 LCD Compatibility"

Hi! im having some problems with one iPad 6th Gen.

I broke the LCD and i bought this one

But when i try to turn on the ipad, they shows light but no image. What can be the problem? Seems like a loop

Pd: If i use the old LCD i see image, so i think the ipad its ok.

Sorry for my bad english, i hope anyone can help me, thanks.
