At 1545CDT I was watching OTA channel and suddenly it went dark and the audio quite. I scrolled and selected some other OTA channels and they indicated no signal. Satellite channels however could be selected. I connected the antenna to the Plasma directly and it worked fine. Reconnected to the 622 and still no OTA. Then did the famous "E* fix" (unplugged the 622 for about 10 seconds) and service was restored. Is this yet another 622 anomaly?
