Call it in, make the warranty claim and if no action, move to returning the set as a defective product.
I have a Samsung TV model # un65fh6001 and updated the firmware to 1004 from 1011. The result is I lost the Auto-motion feature resulting in a permanent soap opera effect. I also lost the ability to adjust the backlight. Subsequently I had to install a new mainboard to correct the issue with the old firmware. However as previous to the update the picture quality in dark scenes is poor due to "crawling moss" or dynamic false contouring. Any suggestions would be appreciated..
