Does the original screen flicker if you re-install it?

Screen flicker is usually caused by improperly seated or dirty connectors. Take a closer look, under magnification to see if there is any debris impeding a good electrical contact. You can also clean both sides (flex & logic board) of the connector with IPA (>90%). Sometimes, the retaining bracket has to be installed completely before flicker goes away.

That looks like a defective screen. Do the IP7 and IP6S do exactly the same thing? If so, you may want to consider changing suppliers.

Along with the flickering, it turns colors sometimes. It seems like certain colors triggers it. What do you think it would be? Maybe a cheap screen that was used?
