I'm having a problem setting a password on the LG 42LH30 picture settings. For some reason every time I try to setup a password the tv gives me a msg: "Wrong Password". I don't understand that. The tv is brand new, we just got it so obviously no password was ever set. This is the first time i'm trying to set a password. Anyone with a 42LH30 can shed some light on this issue? thx for any help.
