My Olevia Flat Screen tv made a loud snapping sound and now the color/contrast/sound, etc. is messed up. I got the colors to acceptable level, but now all the shows I watch say V-chip locked rating PG13 or something similiar. I never set up parental controls, so I don't have a password to unlock it. I have tried so many combinations suggested, but nothing works. What can I do to unlock this feature? Thanks for reading this. bj
