If the lines are colored DIAGONAL lines, they are referred to as "retrace lines," which indicates either that the picture tube bias is set too high, or the brightness level is set too high.. If the blur occurs when the image is particularly bright or a particular color is bright, it is referred to as "blooming." This is caused by either a weak high voltage circuit or because the picture tube bias is set too high.

Is the picture set very bright? Try reducing the brightness control to a level where the retrace lines disappear, and reducing the contrast control below the level where the blooming occurs.

If the television is more than ten years old or has many hours of use, the picture tube may simply be deteriorating normally. By nature, they have a limited life span. Before you decide to throw the set out, if you are technically-inclined, try adjusting the bias and screen drive controls for the television as recommended by the set manufacturer (you didn't specify what make or model the set is), and you may get a few months or years of additional life out of the set.

I believe you have to have a remote to set your picture to the right size. You can get a universal remote that is recommended for your television set.

contacting Sylvania customer support with the model and serial number of your television, which can be found on the back of the set. Sylvania's toll-free support number for LCD television sets is (866) 321-3927. Call (800) 968-3429 if you have an old tube-type (Cathode Ray Tube) Sylvania television.

this is called a "collapsed" picture. it is normally a simple repair for a tv technician. simple for them but almost impossible for the average consumer. if the set is fairly new and not under warranty it might be worth your effort to take it to a tv repair place and get an estimate on the repair cost and go from there. if it is an old set it is time for a new one.

There is a button labeled "ZOOM" on your remote control, press it to cycle the ZOOM settings.

Maybe it's something with NTSC/PAL settings, or SOURCE SELECT. Check troubleshooting in your manual.
