I live in South Jersey near Philadelphia so we've got the Big three
networks on channels 3, 6 , and 10. All 3 have poor reception. Channel
7 which is Fox and has Pro Football is perfect just like the higher
channels. The HBO channels 14, 15, and 16 are inbetween reception wise.
I tried find a similar problem using google but I didn't have any luck.
Anyone know what's what with this?

What does this have to do with cable modems? If you have a problem with TV
reception, complain to your cable company.

Remember that the lower channels are being broadcast from the local
analog stations. Cable has appropriated the frequencies for their cable
channels.
What is probably happening is that your TV is picking up the local
signal over the air at the same time the cable is sending in their
signal. As a result, you may be getting interference.
Your TV may not have enough shielding to combat this, but if it is a
current model, the likely cause may be that your coax cables are
deficient. Be sure you have Comcast come out and provide their cables
with the proper connectors. The Radio Shack/Walmart quality push-on
cables will not work too well. You may also see the effect on the higher
frequency channels.

Years ago, when I could see the CN Tower (where most of the Toronto TV & FM
stations are located) from my apartment, I had a similar problem, even with
good quality cables. I was able to resolve it, by placing ferrite chokes
over the cables, near the connectors. This prevented signals that were
being carried over the shield, from entering my TV & VCR.

You'll often see similar chokes on computer monitor cables and others, where
they're used to keep a device from causing interference.

I had a push on coax cable, and saw the symptoms. I fixed this problem by
replacing with a cable that has lock nut. Occasionally the nut works loose,
and I'll see the same symptom as the OP. So, check all the connections.

I had problems just like you with comcast, I got a dish setup and now no
more problems. The BS about the dish going out is exactly that, BS. In the
last year I have lost reception for about 10 minutes.

Man oh man! You guys are great! Thanks for all the info. I let you know
how I resolve the problem.

I looked on my TV remote's menu and I didn't see a setting for catv/ant
on it. I have seen the setting on remotes for other tvs.

I have had Comcast come out for other TVs and they've always blame the
set.
This is a new TV so I figured I'd look on my own. I am in Runnemede.

If your reception via antenna is better than via cable, push the CATV
button!

(Ok, my cable guy had to tell me that!)
