Sony bravia kd-55xg8196 backlight bleed

[picard01]

I have a huge problem with the tv. Mostly in dark internet movies and dark scenes, the backlight of the panel brightens and darkens at a very disturbing rate making it impossible to watch the movie. Things became worse with the last firmware update.
