Missing 2 Comcast HD Channels

I am missing USA HD and Discovery HD Channels. Rest of the channels come in. I have called Comcast numerous times they have reset the box -sent signal- and still nothing.

Had a Tech come out and replace the box to a 3416 and still not getting the channels.

When looking at the hidden menu the 2 channels have no signal or frequency...everything is N/A.

Anyone have any input?

I had the same thing happen with a new TV and cable box. I couldn't get 3 of the HD channels. I had the cable splitting to another room. When I eliminated the splitter, all the channels came in. I guess the split signal was too weak. If you don't have a splitter, you should probably have Comcast come out and test the signal strength.

I had the same problem-- three channels would not come in on one STB . . . I switched cable boxes-- same problem. Called my cable company and they reset the box-- same problem obviously. They sent out a tech and he put a powered amp on the line going to the third floor-- no more problem. It was just a long run and the signal needed a bit of a boost. Comcast will fix this.
