Strange screen issue with iPhone 4

[CycloneHooah]

Hey guys,
I am having a strange issue with my iPhone 4 screen (just replaced the screen, have repaired many other iPhones and they've had no problem). This issue is one I've never seen before.. When the iPhone is turned on, horizontal lines fade across the screen and it appears to "warm-up" as old CRT tvs did. Could this be a faulty lcd display? Could a connector be jacked? (I cleaned the screen connectors on both the board and the screen side with isopropyl alcohol and dried).

Here's a video of the issue :
