However, there is a problem with channel 40 with the 2160A that the Visio TV handles fine. Channel 40 has 4 sub-channels: 40-1, 40-2, 40-3, and 40-4. A scan using the Visio TV finds these channels and using its channel up/down works fine in that I can go from 40-1, to 40-2, to 40-3, to 40-4, and then to 45-1.
The 2160A also finds these channels, but when I use its channel up/down it skips over 40-3 and 40-4. So I can go from 40-1, to 40-2, and then it goes to 45-1. I can enter either 40-3 or 40-4 directly on the 2160A and it tunes into them correctly, but when I use the channel up/down it skips them. For example, I can enter 40-3 directly, use channel down to get to 40-2, but when I use channel up I get 45-1 instead of 40-3.
Does anybody know why this is happening, and is there a solution?
