Hi idesignstuff,
Thank you for your interest in TweakTV. We don't offer up Service Menu codes here. All of us have solid relationships with all of the manufacturers in this business, and I can tell you that they don't appreciate people publishing service menus info on public forums.
While we don’t have your exact model in our data base, we do have the settings for a model that is similar to yours, the LC-32LX85. Try them at the link below, and let us know if you see any improvement.
