JVC AV 28 WFT TV MODE SERVICE

For any one do not forgot to write the TV settings down before changing the setting to comensate the RGB picture shift.
For use under DEF Menu, to access service mode press i and mute together.
Settings from three different sets, in various stores so I know the service setting haven't been messed with. To obtain default settings simply use an average of the values below (or try each set), most of settings are similar to with +/- 1 across the three different tv sets.
