Vertical Lines UN75NU710DFXZA

Just picked up a 75" 4K from Sam's. Plugged it up and immediate smokey white verical lines across the screen. It's not as noticable when a bright picture appears, but anything where the pictures is dim or dark it becomes very noticeable. Ive played with the puctures settings to no avail, pretty disappointed. I would love to fix it instead of returning, if anyone has ideas?

Alright, I tried the following troubleshooting steps Samsung Customer Service recommended:

While tv is on, unplug power cord for 30 seconds.

Cold boot.

Factory reset.

Turned off eco solution.

Still have the vertical lines unfortunately, so i think I'll just return it. I appreciate eveyones input/suggestions.
