I went to TWC Atlantic Ave. to exchange the box for another (same model) and there was no improvement at all. OTA equivalent channel 2.1 looks fine, and when I plug the cable from the wall directly to the TV's coax jack, bypassing the box, the picture, on channel 17.1, is also fine. So, problem has to be with the box. And the problem is only
on channel 702, CBS HD. Anyone else experience this, or have any ideas? And, does TWC offer any other non-DVR box other than the Samsung? Thanks.
I'm out of my depth here, but from reading the board over the years I'd offer the following idea for further exploration:
It may be that 702 is on a frequency that happens to suffering on your infrastructure (cables, connectors, splitters, etc).
As I understand it, all the cable channels are sent on particular frequencies over the physical cable - and while overall signal strength is relevant, it is also possible for something in the line to be causing a particular frequency or range to suffer, thus tripping up specific channels.
Someone more knowledgeable might be able to say whether the direct-coax frequency of CBSHD is the same as the via-cable-box CBSHD. If they're the same (which would seem likely), my theory is of course garbage since you're OK going direct-coax.
[And if all of the above is wrong or misinformed, please don't be shy about shooting me down]
