I have an LG 42LB1DR LCD TV. This system has a built in DVR which I love to use. However, at certain times of the day (5:43pm and 10:29pm among others) the TV will "click" and go from standby mode to off. The only way to get the TV back on is to wait anywhere from 10 minutes to an hour or unplug the TV. I can't use the remote or hit the "on" button the TV to get it back on. If I take the cable card out of the system, the TV will still click at those times, but doesn't go from standby to off. If the TV happens to be on, then there is no adverse affect. Two different LG reps have worked on the TV a total of four times, replacing the logic board and updating the firmware with no apparent improvement. They are now telling me it's the cable card, although it's been replaced three times. Does ANYONE ANYWHERE have any advice? HELP!!!!!
