No Way!

I wanted to get two of the "Free" adapters.

They said I can get them free now, but they'll start billing me $6.50 + tax  (or the prevailing rate) each month for the "Free" adapters beginning October 7, 2017.

I guess they are kinda free...

:bang:

Yes, I agree the cable box is not connected properly and when I put it in it's proper configuration it works fine. I've just been a Tech for so long that things like this bug me. When something like a power cord from a disconnected cable box is uplugged from a power strip it caused the TV conected to the same power strip to lose it's signal.

The power strip seems to play a role in this. If I plug the cable box into another AC outlet in the room I get no signal.

It seems as though there is some kind of communication traveling from the cable box power cord through the power strip and through the power cord of the TV.

Or could the cable box be generating (or leaking) an RF signal that the TV picks up?

Anyway, I'll take some photos and get some model numbers when I get home tonight. Maybe I'll monitor the line with a scope to see if anything shows up.

Noticed I'm getting nice HD reception directly from cable modem. HD cable box is not part of the circuit except for power cord being plugged in (nothing attached to input or output connectors). If I unplug cable box power cord my Samsung HDTV loses signal. Strange....unless some kind of communication being sent via power cord....
See attached diagram.
