Well think of it this way:
You either keep it and have a semi functional screen that cost you like $200, that will die soon because it seems like it was going in the first place,
OR
You did what you did and RMA'd it for a brand spanking new one still in shrink wrap, and the fresh smell of Hong Kong. Even though it will take a little bit of time and cost like $20 in shipping, you will like the end!
It may hurt now, but you made the right choice!
by the way, great way of using video to diagnose problem. I love technology!
