SOURCE: Video settings
I think this is what you need.
Before pressing Menu make sure the picture mode button is set to User then you can change your contrast etc.
Also this is how to get to the factory settings menu but don't touch anything your not sure of or you could really mess up your tv for good. Don't change settings in here unless you know what you're doing. Don't blame me if you mess up your telly.
