*Here's a THX Picture Unlock tip;
Purchase a regular LG remote control like (AKB72914050) as pictured above (eBay).
Press Menu > Picture > And Highlight THX Cinema or THX Bright Room in Red > Now press code 8741 from the remote controls keypad.
THX has to be highlighted in Red while already selected and sitting in the Picture menu, not while in the picture mode selection drop down box.
This will unlock the locked out THX picture settings so you can tweak them if needed. I found this very useful in tweaking "Tint" when watching Comcast Movies channels that were not broadcasting the original color correctly. Same for DVD & Blu Rays. Just zero the "Tint" etc, other tweaked settings back out to where they were when your done watching.
