Refurbished 65" TV - first time plugin, 30% of the screen is dead!

Hello, a couple weeks ago I got one of those TCL 6 series 65" screens, and I just got around to trying it out yesterday. To my surprise and dismay, while the physical screen looked undamaged, it was clearly dropped during the refurbishing/restocking process at some point. The Microcenter return policy doesn't say much about refurbished units like this, so I'd love some clarity before I try to head in for a return:

1. The "original packaging" was a nondescript, blank cardboard box that had to be cut open to get the TV out safely. Do I need to return the TV in that box taped-up? How best should I do that?
2. For the same reason, the materials for the TV/stand cannot be put back into the original baggies they were in. Should I take apart the stand and place the screws in a ziplock bag or something?
3. If there are no more of the 65" TCL series 6 units available at my location, are there any other options other than just getting a refund for this minor league pain in the ass?
