Had my set for three weeks just for a cinema in my loft so only watching blurays. Have an issue in darker scenes (randomly) where the picture will flicker brighter and darker, this can happen quite a bit when watching a movie (happened last night watching 'Drive'). It has happened on every movie I have watched. Have tampered with the settings, tried a different hdmi cable, to no avail. Maybe the set needs to bed in a bit. Bit worried as it's doing my head in. (using a 3d bluray 500 player). Any ideas anyone. This is my first plama by the way.
