It looks like you are saying standard definition pictures do not cover the screen like HD pictures do. Standard def is formatted 4:3 and high def is 16:9. They are not the same so your high def screen is made to display the not as tall but wider high def picture. In order to fill the screen with the taller and not as wide 4:3 aspect ratio std def picture you must tell the TV to stretch the picture or otherwise fill the screen.The TV will have controls you can exercise for this purpose and you can set it up to always show std def in a particular manner. The alternative, if you want the standard Def picture to look true to form, is to view standard def in Letter Box form. It's appearance will then include black panels on the sides of the picture. So the problem is not with the TV but in accepting older format pictures playing on newer format displays (TVs.)

Make sure your using a cable box that is compatible with a high def tv, if your tuning a high def channel and your converter does not support high def, it will only play the sound, no vidio at all.

Make sure your not trying to watch a high def channel, you will get sound but no picture if tuned to a high def channel on a non high def input or cable box. Try a vcr or dvd player connected to the unit to varify the picture tube has not gone out.

That is because you are watching the picture in the 4:3 aspect ratio. This is normal when you are watching a channel that is being broadcast in 480 or digital. But once you tune to a station that has 1080 or at least 720p which is true high def then the picture should expand to 16:9 aspect ratio. It will switch between the two automatically as it determines what type of signal it sees. You can force the resolution to change by pushing the format or aspect ratio button on the remote but you will lose picture quality.

The HD reciever shouldn't be the problem.

If you recieve an image with a 4:3 aspect ratio, the image will be displayed at that ratio on your HDTV unless you specify otherwise. To do so go to your TV's Setup screen

setup
Choose picture formats
select smooth wide as your default

***Some digital (ATSC format) stations may transmit 4:3 images in a way that will not allow expansion. You will be unable to adjust the picture format.

Hope this helps!!!

The new tv we bought has a setting for 'theater' settings. These are different settings in which to view the non high def channels and shows.

if you have a cable box then it is probably the resolution settings in the cable box, what type of cable box do you have

Define "tune" please. Tune channels, tune hi-def channels, tune picture performance, or something else altogether?

I have a Toshiba 50HP15 PLasma flat screen TV. Its been working tone for 2 years now. All of a sudden without warningm the right 1/3 of tghe picture is missing and is black, where as the other 2/3rd of the picture is great picture and in HD. When I press DISPLAY on the remote control is says FULL 720p. When I press the Picture Size button on the remote the message NOT AVAILABLE come on. Anyone with suggestions. Thanks
