Audio but scrambled picture with coax cable on lcd tv

I have comcast cable and i am using the coax cable because i do not use a converter box. my tv is a westinghouse 32" lcd. i have the tv do an automatic scan of all available channels. it finds 65 analog and 350 digital.
problem 1-i can hear audio from all channels but see video on only a few channels, the others habe a green and white pattern flashing at high speed.
problem 2- w/ digital i get some channels but not all 350, i get about 20.

all i would really like to get is channels 2-65 if possible.

Hookup the comcast hd box to my new lcd tv?

You can use either component (Red/Green/Blue video and red/white audio) or HDMI cables to connect the Comcast HD box to your TV. Most times you can get these cables for free at the Comcast front counter.

I am trying to hook up my tv through a onkyo receiver with polk audio speakers what is the best way to hook this up my cable system is from comcast with their hd converter box.

Use either an optical cable to your reciever or a digital coax, which ever you can or do use will give you dolby digital. Unless your onkyo has hdmi swithching. In that case you will need 2 cables, those are the best for picture and sound all in one cable.

How to Hook up HDMI from Comcast Motarola Cable Box

Connect the HDMI outputs on your various components to the HDMI inputs on your receiver. Connect the HDMI output on the receiver to the input on your TV. HDMI incorporates digital audio, so no need to buy optical audio cables. If your receiver does not have HDMI inputs for all your components, you will need to make a choice. HDMI = Best, component video + optical audio = second best, S-video+ optical audio = third best

No sound on NON HD channels

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

Magnavox 15" LCD TV

If the LCD only has coax, it will never display a HD picture quality. However, the Comcast HD Box will still display a picture using the coax connection. So, you could watch any HD channel, but the picture quality will not be high definition.

Female coax connector in tv bad?

If your cable converter box has audio/video connections on the back of it,you don't need to worry about using that RF coax connector. Just hook it up the same way your DVD is hooked to the TV input jack. Get a 3-wire cable (yellow-red-white)hook it to the same colors on the back of the cable box and hook the other end to an unused input on the back of the TV. Then select that input with your remote and watch TV.
