I feel like this is a stupid question, but I can't for the life of me figure out why this is happening on my 42PX60U. I've done some searching and looked in the Panasonic FAQ, but so far haven't found what I'm looking for.
When I go into the normal menu on my TV, I find that a good number of the options are disabled (or greyed out). I don't have the TV in front of me right now, so I don't remember the exact names of the options, but a few examples of the options that are disabled are:
The option that controls how light or dark the side bars are
The option that controls where the audio comes from on HDMI input 2
Does anyone have any idea as to why I wouldn't be able to change these options? I'm guessing it is something simple, since it doesn't really make sense to me that I can't change these options.
