This is a ~ 4 year old HP Pavilion laptop with LCD display.

There is a bright vertical area on the left end of the display that is
incongruous with the rest of the display. It is only on the left end.

This image also shows the lighter central area of the display which is an
artifact of just viewing it on-center (or nearly). This phenomenon can be
ignored.

Is the stripe due to LCD problem? Or...?

Thanks.
