What Are These Metal Shields And How Are They Attached Nexus 5X

Chosen Solution

Hey, I was doing a Nexus 5X screen replacement and it seems that I have unintentionally ruined the new LCD. A small metal part has become detached from the flex cable. I connected the LCD to check it and the image went completely haywire. Could it be from this small part? What does it do? How can I attach it back? There doesn’t seem to be any glue involved.

Maybe the connector is not seated properly, try and reseat the connector. As for the metal piece I think those are just glued on, part of shielding, use light sticky glue to reattach.
