We had a severe cold front come through NE AR yesterday and the temperature dropped 25 degrees in an hour. The winds were 40mph with gust of 70 and upwards. Several people have lost their over the air channels using the built in tuner in the HD receivers. Has anyone else ever had this problem. It's not the station or even the ant. because other tv's are working without going through the receiver. My dealer said that about 5 to 6 people has called with the same problem. Thanks for any info. BTW, I have a 722 and 211 and no OTA on either.
