Before you take the set back, it's worth trying one last test:
- Set Smart Dimming ON
- Set your Backlight somewhere around 50-75
- Set your Brightness somewhere between 47-50
- Turn Auto Brightness Control to HIGH
Auto Brightness Control will dim the overall light output based upon ambient light, but it also does a phenomenal job (in my case at least) controlling flashlighting from the edges like what you're seeing. Your setting for Backlight (set it before you turn on ABC, since it'll be greyed out) will determine the maximum light output. The ABC settings of Low, Medium and High also affect how much dynamic range to allow between dark and light by limiting the high end of the range. So you have a lot of flexibility between both settings.
It's also worth trying ABC with Smart Dimming OFF to see if you get better results. For the record, though, ABC almost eliminates flashlighting and blooming caused by SD on my set (it'll still faintly be there in the toughest scenes, but nothing like what you're seeing).
But if that doesn't work, then yes, it's probably due for a return.
