neomorphic

I just bought one of these televisions (LG42LH40) and everything was fine until I plugged in the HDMI cable. Then the lip-sync problem started to annoy me like crazy. So I googled around and found the following little snippet of advice. It seems to have solved the issue, apart from a little tweaking to get the number set correctly for my particular set. Shame this doesn't show up more frequently on the net as there seem ot be a lot of people having problems getting this working. It also seems that LG tech support doesn't know how to do this either.

LG 42LH40 42-Inch 1080p 120Hz LCD HDTV, Gloss Black 1) press and hold the menu button on the side of the TV then press and hold the menu button on the remote until the display says "Enter Password" 2) enter four zeros from the remote control to get past the password screen (you should now see an "IN START" menu with all kinds of information listed) 4) look at the lower left corner where there should be a numbered menu -- menu option 4 should say "System" 5) use the down arrow until the word "System" is highlighted (pressing the number '4' will not take you down the menu) and press the enter key (you should now be on the System menu near the middle of the screen) 6) press the down arrow to option 9 "Lip Sync Adjust" and then press the left arrow to adjust the value to zero (mine was set to 20 from the factory) 7) press the return key to get out of the menu and bingo, you're done!
