Format seems to be stuck

Go to menu then got to picture then go to advanced picture settings and turn off the auto format button

Check your cable box remote. You may have that stuck on stretch or zoom. Look for "ASPECT" above # on remote.

You may only need to change the format for the picture. Check your owners manual for how to change the picture format, or aspect ratio. The tv may be in the zoom mode the way you describe it. There is likely an option in the menu to allow the unit to automatically set the format based opon the signal being received. Only some of the programming you see is actually HD. The Super Bowl was broadcast in HD and has a 16:9 aspect ratio (width to height). When this set is adjusted for a correct HD display I'm confident you will be impressed. So I believe this is a matter of a customer setup with the remote. If I had the unit in front of me I could offer more detail. I hope my general opinion helps.

Run it through the different 'MODE' settings. it may really be on zoom, or just confused.

Also, try unplugging it for a minute. plug it back in and see if it's better.

Please, I need support of camera technical carl zeiss vario tessar with otptical zoom 40x

Try to put it on super macro and see if this will reset the zoom function.
Also try to switch between the settings that allow the digital zoom, as compaired to those settings that only allow optical zoom.
If these do not work, you may have a lens that has been dropped, or is stuck, and may need to be serviced. I have the S700, and have never seen this error before> good luck.

You would look for a format button on your remote.
Dish Network: bottom left the asterisk "*" button
DirecTV: top left, second from the top labelled "format"
Cable remote: look for format, zoom, or aspect ratio

Pressing this button should scroll you through the options.

The left and right arrows on the RCA remote control are the picture format buttons.....

Problems with screen size
Look out for 2 x 2.2uF electrolytics (sometimes red in color)
Vertical height oversize
The eprom was found to be faulty (nvm)
Pressing the screen format button displays wide, smart, zoom and 4:3 modes but settings have no effect on picure
Enter TT35 in the service mode to select a 4:3 CRT

In addition to the optical zoom, this camera is equipped with a super zoom and digital zoom for taking telephoto and wide-angle shots. The super zoom and digital zoom cannot be used at the same time. Super zoom is used to extend the optical zoom up to 14× magnification. However, the resolution is automatically fixed at 1600 ×1200. Digital Zoom is used to extend the maximum optical zoom to approximately 40x. However, pictures taken with the digital zoom may appear grainy. Camera shake is likely to occur at these higher magnifications, please see “camera shake” question for further details on this.
