Hopefully I can explain the problem well enough... also hoping it's something simple I'm missing because it's a bit frustrating as of right now.
So, I've had no problems receiving OTA channels for the past 2-3 years on my 32" inch LG. It was a simple coax cable plugging into the back of my HDTV, search the channels, yadda yadda. 32-1, 2-1, 5-1, etc. those have all worked fine for me for years.
Now as of last week, I received a letter from Comcast stating that I have to get their Digital Box as they are converting all of their signals to digital. No biggie, free of cost, get On Demand now... okay.
After setting it up today, I began to wonder how I would receive my OTA channels going forward. Before I would just do 2-1 or whatever to get CBS (Channel 2)'s HD signal.
Now that I'm bogged down by this Comcast digital box, all the channels and the cable go through the box. Okay. So I switched to CBS, and then found the CBS-HD channel in Comcast's listings.
Now when I get to the CBS-D channel, I can hear audio, but I get no video. What gives? How can I continue receiving and getting to my OTA HD channels with this new Comcast Digital Box.
Also, I don't plan on getting the HD package from Comcast, I was more than happy getting the 10-11 OTA HD channels I was getting for free (CBS, NBC, Fox, PBS, etc.)
Hoping this is a simple problem... please let me know if you need any clarification or if I didn't explain properly. I await your help!
For some more detail, here's how it's connected. Out of the wall into the Cable In portion of the Comcast Digital Box. Coax cable runs from Cable Out to the TV. No other steps, pretty direct.
