Advertisements First off, the channel (4-1 in the Charleston SC area) is listed twice in the Channel List. Regardless of which is checked or even if both are checked, I get no picture when attempting to watch the channel on TV. When I do a Signal Strength test, They both show strength of 72. During the signal strength screens, I get a picture and sound on the second 4-1. They both show the same frequency - 34. When I am on the second 4-1 on the tuner, I get the error, "Problem with the signal on this channel. Trying again. V53" This has been occurring for a few months. Channel 4-2 plays with no issues.
