Why is the display not working on the Phone 5?

Question

iPhone

Actually change the display module for iphone 5. It was tested before replacement. Plugged in with the battery off. At the moment when the module itself was inserted into the case, the device was already turned on (it was very tight into the case and it was necessary to somehow take care not to press hard and not damage the module), at a certain moment a gray background and several multi-colored stripes appeared instead of the image on the right side. After that, the battery was pulled out and the module turned off. The module is no longer active. Actually the question is: is there a chance to revive it?

Answer 1

Damage to the touchscreen cable or its connector. The next thing to look for is the components at the connector.

Answer 2

No, you overdid it and passed it on.
