When power up the TV, I only hear the sound with no picture. To set it back to B550_FBE, I need to use the service menu navigation without being able to see it and set it back to B550_FBE. Can some one please post the navigation in the service menu (Info, Menu, Mute and Stand By). Thanks a lot. bisonih Home Entertainment Tue, 08 Sep 2009 15:44:21 +0800
