The 68T90 is not an HDTV, and does not have an "Aspect" button on the remote. This is a normal SDTV (standard def) TV, seemingly made for European markets. Owners Manual
In the TV menu, there is this:
Picture format selection.
Select picture format between :
- 4/3: normal size
- 16/9: 16/9 size
- Zoom : expanded picture
In "Normal size" mode, with standard 4:3 video source images, you will always lose some of all edges of the image, due to what's called "overscan". This is an ancient process that causes a small amount of the original picture (typ. 2-3%) to be lost. In the early days of analog TV's, this was good, as it prevented the edge of the scan lines from being seen, which would look bad.
With the advent of HDTV, all signals are broadcast and received in digital, and is therefore totally predictable as to what will be seen... you will rarely lose even 0.5% of the image on a good HDTV.
However, having said all of that, if you are losing a significant portion of the left/right sides of the image, your horizontal deflection circuits may have gone bad. Watch for a commercial with a large circle, if it's significantly "out of round", then yes, you have "hardware" problems.

Try the aspect button on your remote, or if you have this hooked up to a cable or satellite converter, there are screen resolution preferences, you can change the screen resolution here, go the the menu portion and look for video/audio field
