Turned on my Sony Bravia XBR-43X800H this morning, only to find that there was no sound on any channels (antenna). TV is NOT on mute, and was working fine last night before I went to bed. I know my way around electronics, menus, and remotes. I also noticed that 9 of my OTA channels (Scripps/ION) were now completely missing. I rescanned those and did not get anything. Not even a flicker. They had been perfect - with next to zero interference for the whole last year. AND one of those channels, QVC, showed CBS Mornings (?!!) as the current program on the now otherwise blank channel. Completely weird. Also, the channel Guide still shows all the programming for the (lost) 9 channels. Is the complete lack of sound on any channel, PLUS the loss of nine Scripps/ION channels (at the same exact time) a coincidence? I can't believe it to be. Anyhow, a restart cleared the volume issue. But a rescan did not find any new channels OR get back the 9 that I lost.
