I have a 32" Samsung LCD-TV. exchanged digital cable box for HD box. The picture for both HD channels and Digital channels is not full screen. how can II get full screen for both HD and Digital channelsInput is HDMI :HD STD. The picture is never full sized in Wide or Zoom mode. Panorama is not available for HDMI or HDTV. I must operate in Wide to get the full vertical picture but the picture never fills out the screen horizontally. Please let me know if there is a solution to this.

I think your cable box is old version together with weak signal caused this problem. I guess you are using coaxial cable hooked up to the TV at TV cable input jack.
At the TV there are some better quality inputs which are real digital transmission (audio and video) HDMI and components (digital video and analog audio).
The most simple and best quality is HDMI provided the box has HDMI output.
Secondly is component inputs. There are 5 cable trends in which 3 of them (red, blue, green) for video and the rest 2 are for audio (red , white). The cable box should have same color accordingly as ouput. Please note that the color must be matched otherwise you will see the screen has one color only.
Playing a DVD player to see picture good or not. If picture is good, TV has no problem at all.
Dont use the HDMI connection OR replace the main board. Its directly soldered to the main board. The back should come off IF you have removed ALL the screws and the little screws things that hold on the VGA connections etc. There are also some obscure screws holdin the back on.
Unfortunately if you chose to view the non HD channels in wide screen format, you are going to have the top and bottom of the screen cut off. Eventually this will not be a problem when everything goes to digital. However presently non HD channels are presented in 3:2 ratio where as HD is 16:9, So your choice really is to view them with the lines on either side for now.
I do not have an answer for the white flickering lines.
To get the BEST picture out of your 1080p unit I highly recommend using HDMI cables to hook it up.
First lets determine where the sound is missing. What are you using for sound. RCA jacks? HDMI cable? If you are using the HDMI cable, please make sure the correct sound is selected in the Cable box. In New York Cable Box, The HDMI sound has to be selected in order to get sound using the HDMI cable. Hoping that all other settings are ok, You may need a new signal board. Part Number BN94-00629R. Average Cost $176.14
If it does it only on HDMI, then, the problem is the Main PCB. The HDMI cables are to heavy for flat panel sets.
If the problem happens on just one input such as component and analog, then the problem is more than likely the source.
Does the problem appear on DVD, but not the cable/satelite?
If the problem appears on every input, then the problem is the main PCB.
Hope this helps.
