The result is uneven wear of the phosphour in the 3 picture tubes which will show up as a discoloration (most noticable in white images in b/c they appear a dingy brown color instead) either where the black bars were or inside depending on if yours shows black bars or white bars when you watch it in widescreen. I work for a television repair company and we see these all the time. It doesnt take long for this to happen b/c the tubes' emission is so intense in order to project the image.
The companies will not cover this under warranty even tho it is their fault for putting the stupid option on the tv in the first place. Most of the manufacturers are starting to tape a warning on the front of the tv to notify customers.
If this has already happened to your tv, call the manufacturer or the place you bought and raise HELL for their failure to warn you.
