Sony Bravia KD65x8500D - Random light sheen in dark scenes

[Brands]

Hey guys,

I have been trying to figure out why i get some sort of white sheen popping in and out over the entire picture during dark scenes on my 65x8500D. It constantly flicks to bright and dark depending on how dark the scene is. It also seems to do it when people talk. I just want a crisp well saturated picture. It looks sort of like backlighting coming to the very front of my picture, covering the entire screen

Does anyone know why this would be happening?

Regards,

Brand

I had a similar thing when using subtitles, each time they changed the screen would for split second flicker bright.

Was you using subtitles when this happens ?.
