Help needed - Samsung Plasma picture problem

[FilmFanSam]

Hi guys

I got a brand new Samsung PS51F8500 on Saturday, and when watching Blu-rays, there appears to be a short 'pause' of sorts appearing in the picture (like if i was to pause the picture for a second)- only for a split second, and usually appears right after a black screen (watching modern family where the black screen appears after each segment in the show)

I have tried all the different settings, but nothing is helping.

I am wondering if its just a faulty panel, and maybe I should return it for a replacement?

or is there an easy fix I'm not seeing?

This TV got universal praise on review sites and cost me €2000 so I definitely know this problem shouldn't be happening.

Any help much appreciated!

Thanks
Sam.
