Riznet,
Which inputs are you trying to adjust the settings for?
I have a LC37G4U also and have found that the 'best' (subjective) settings for most component/DVI sources are as follows:
Temperature level: Medium-Low
Backlight: Middle (Turn on OPC, to help set this automoatically)
Contrast: 0 (i.e. all the way to the left)
Brightness: 0 (i.e. middle of the bar)
Color: -9 or -10
Sharpness: -2 (for HD or DVD) and +2 for SD
On the Advanced page: Set Film Mode On; Black Enhance On
On the last menu -> set Quick Shoot On
Hope this helps
It would help to know which sources and on which inputs you are trying to configure.
