Default Bright stripe on LCD display

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...?


It is such a terrible photograph that it looks mostly like a reflection
of something white you left on your desk off bottom right. It doesn't
look abrupt enough to be an LCD connection defect which tends to give
very sharp linear errors on bit/byte/word boundaries.

Looks to me more like a physical fault with the backlighting optics. An
impression heightened by a dark ridge to the RHS of the brighter patch.
