Recently I posted about having solved my cable cut challenge with an RCA ANT751R antenna in my attic pushing 4 TVs. I am ~40 miles due north of broadcast antennas. Here's signal analysis:

Using a compass app on my samsung galaxy S set to magnetic, I pointed the antenna 180deg mag. Nearly all local channels came in clear as a bell on all 4 TVs without signal amplifier, tho 8, 13, & 39 were a bit finicky on farthest reach TV. A 10dB signal amplifier solved that problem. All channels clear & constant on all TVs.
But something weird happened last night while watching "Sherlock" on PBS (8.1) on the bedroom TV, which is a ~2007/8 Emerson ~21" budget LCD flat screen DTV ready TV. About 3/4 thru the program the audio of 8.1 was replaced by the audio of 8.4 (an audio only channel), also the audio on 11.1 & 11.2 went out of sync with video. 8.2 & 8.3 were unaffected. I checked the other TVs, no problems at all.
I hope this is a TV tuner problem and not my antenna installation problem. I can swap the TV out tonite with one of the other TVs and if the problem disappears I suppose that would isolate the problem to the TV. I am posting here just to see if you experienced OTA TV members know what happened here?
Thanks,
Jim
