Long time lurker, first time poster. I just noticed today that I can't make any adjustment to my picture settings, all the sliders seem to be locked. I spent over an hour on the phone with Vizio customer service but they were not able to help me. We did a factory reset and they said they pushed a firmware update (which I know they did not because I checked my version before the reset), FW is at 2.0.45. Another thing I noticed is that I no longer have a tab for Parental Controls. My unit is actually a E701i-A3E if that matters, but I came across this thread while Googling for a solution and thought I might have better luck in asking the community here.
If anyone has any ideas on what the problem may be, I would sure appreciate the help. Thanks in advance and Happy Holidays!
