TV is less than 2 months old and having the exact same issue here as well but on a larger scale. Flickers much more and sometimes will go completely black to on again in a split second. This happens on EVERY channel on Cable TV. Not happening to any of our Samsung TV's in the house. Absolutely ridiculous. Someone needs to take ownership and fix this - whether it's TCL or Roku I do not care. FIX THE ISSUE.
