Hello, I replaced broken display on my i7, everything works properly instead of display, it looks it’s dead, i tried another display the same result, i also see him in iTunes and it’s vibrating...

Can I assume you performed the replacement procedure yourself? If so, find a screen replacement guide from a reputable website and follow the instructions exactly how their written. It’s possible you may have missed a step or something isn’t fully connected.

If you’re certain you’ve done everything correctly, consider taking it to an authorized Apple repair place to have them fix it for you.

I replaced about 12 displays so i don’t think i did something wrong...

UPDATE: everything works properly instead of display, it looks it’s dead, i tried another display the same result, i also see him in iTunes and it’s vibrating...

The iPhone was turned off, that’s the reason why it doesn’t vibrate and so on...

Unless you’re absolutely certain both displays aren’t defective then I don’t know what to tell you, especially being that the device still powers on.

Never assume. I've been a systems/network admin my entire adult life and I always think I did everything right until someone else proves me wrong. :-)
