I love the LG Tv's this year. The plasma 42's i would rate as one of the best out there for it's excellent picture quality, their excellent warranty's (2 years) reliabilty, XD engine, and clear filters. All the other sets are extremely good but the 42's stick out since they have this clear filters this year(LG larger sets will have them next year) ANYWAY...
If you are a tweaker.. (and you probably are since you're on these forums) LG included an EXPERT MODE inside it's flat panel TV's for techs, and sales people mainly. THIS IS NOT IN YOUR MANUAL. The Expert preset can be selected in the normal menu but the settings that make up the preset cannot be changed, unless you know the secret sequence followed by the password.
The Tv will count how many times expert mode has been entered for whatever reason but you should know that. Expert mode lets you adjust EVERYTHING on the set better than that of a great computer monitor.
THIS IS NOT IN THE MANUAL
Here's how you do it:
HOLD the MENU BUTTON. The normal menu will pop up but if you continue holding the menu button for about 5 seconds a 4 digit lock code box will show up.
THE PASSWORD: in the shape of a L (how cute for Lg) enter 8741
Bam.. now you can tweak to your hearts content. It has a default mode so if you really mess up the picture you can default it to factory settings.
Have fun
