We have the SVA VR20 hooked up to our Comcast cable and it only shows 12 channels and we have the full through channel 72. What do we do to get all the channels? We just connected the unit directly to our cable tv line.

Cocast may have only transmitting NTSC Ch 2~13 only for your area, to get more channel you may have to use Comcast cable box, I am in bay area, I can get 2~35 for basic plus service, I can get 2~13 for the most simple service for less money. What is your serivce level you are paying for?
Your TV also anly has NTSC tuner, there is no QAM or ATSC turner.

You may have to call Comcast.

You need to upgrade to the high definition
cable box---but first try this. Hook the cable from the wall directly to the tv
and autoprogram it. If Comcast is anything like charter they transmit the local
Hd channels in a format that digital tuner will pick them up. Just channel
up/down and check out the channels with -1 and -2's behind them. Depending on
where you are----your local channels will usually show up wherever they
normally do but with a -1 behind it.
EX: local Fox channel on 47---autoprogram and check 47-1
If this is enough HD for you then get a two way spitter and hook your box back
up and keep using the RCA (composite) cables for the best it can produce.
When you say the remote doesn't get the channels I have to assume the channel entry behavior changed. I am not to familiar with this brand but these are the basics for most tv's. If you have not removed the cable input to the tv or unhooked anything before the problem started here are a few thing you could try. Push the menu or setup button on the remote and under the channel or setup option on the tv make sure it is set to Cable and not Air or Antenna. Run the tv through the auto channel search to reprogram the cable channels. This process can take close to 1 hour on some tv's since it has to scan through the digital and analogue tuners. This will allow your tv to add the correct cable channels and remove the unwanted ones. You should be able to enter the channel number or move up and down with the channel buttons on your remote.
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.
