Any current owners or anyone who's viewed/read about Samsung having a Purple banding issue with the series Samsung listed above. Mine has started to exhibit this Purple band when the picture transitions to a white or very very light grey colour, almost like old TV black/white noise we see when a channel is not tuned in. I changed out the cables, tried all different sources I have and have narrowed it down to the "dynamic contrast" feature set to low or medium......which I never use I just has it on low for some strange reason, can't figure out why I had done that as I always have it set to off. I'm curious if this is a hardware issue that needs addressing before it bleeds into all other settings on the TV and has a dump inside itself. I am going to call Samsung Monday for a service call as My Warranty is up in a few weeks....figures the timing eh.
